So in a typical workflow of a developer, it goes something like this:
You sync your workspace to some changeset, do some work, shelve changes you've made.
My question is, internally, when you create a shelveset, does TFS keep track of which changeset the changes are based on? If so, is there a way to look this up?
My rudimentary understanding is that, yes, this changeset information must be somehow recorded because shelvesets are stored internally as delta's, as opposed to full copies of files and without a record of which changeset the delta is based on, a delta is basically useless.
That may be a typical workflow for your team, but I'd say that it's not a typical workflow in general.
Shelvesets are intended for short-term suspension of work in progress that's not quite ready to be committed to a dev branch, generally in the case of something exceptional occurring that requires immediately switching contexts (e.g. troubleshooting or fixing a bug).
Internally, TFS actually stores most files as reverse deltas. Why? Probably because the most frequently accessed state of a file is the current version, and having to "build" the current version by playing forward a series of changes to the originally file is going to be a lot more expensive. Basically, when you go to look at an old version of a file, it takes the current version of the file and "peels off" the intervening changes until it's back at the old version.
Your specific question is actually directly addressed:
Shelvesets also use the same mechanism for storing their content. However, with shelvesets, no deltafication happens. Each shelveset gets a new copy of its file(s). (except in the case of a merge). When a shelveset is checked-in, a shallow copy occurs and the committed version of a file uses the same content as the shelveset copy of the file referenced. Deltafication will be started on the previous version of the file(s).
So, long story short, shelvesets are not based on changesets.
I concur with Daniel's answer that the files of a Shelveset are copies of new files. However, I'm not sure when this was incorporated but currently in VS2017 the Changeset is actually stored. When looking at the Shelveset Details if you hover your curser over a file among the details displayed for the file is the "Version" it is based off of.

I don't know how useful this will be for the typical user as I have found one of the best features of Shelvesets is the modularity and separation from the version control but it never hurts to have that context.
Cheers!
In TFS, if you want to create a personal branch to try out an idea you
have, you will have to create a branch on the TFS server – even if no
one else needs access to your code. And when you create this branch,
every single file in your project will be duplicated – even if your
branch has very few changes compared to the original one. Now you’re
using twice the amount of disk space both on the server and locally!
Is this true, and one of the downsides of a non-distributed VCS?
Both statements are wrong. (Where did you read this?)
In TFS, if you want to create a personal branch to try out an idea you have, you will have to create a branch on the TFS server
No you don't always need a branch if you're just "trying out an idea". Of course it depends on what you want to do. Saving your work on the server to secure it against drive crashes is what shelvesets are for in TFS (other VCSs may not provide anything similar, which is why you need to create a branch for every idea there). You can even share your code with others without actually checking it in using shelvesets. Even a simple kind of versioning can be done by including the timestamp in the names of the shelvesets, but this is tedious, probably more so than creating a branch ;) Building your code on the server is another thing you can do with shelvesets.
You should read up on when to use shelvesets over changesets on MSDN (there is an article somewhere) to decide whether you need a new branch.
Now you’re using twice the amount of disk space both on the server and locally!
The copying of the code only happens virtually. The SQL Server behind the TFS Server will not use up twice the space, unless every file actually changes on either one of these branches. Until then, both files on the two branches will "point" to the exact same memory on the SQL Server. If you need to work on both branches simultaneously and map them into your workspace, then of course you need twice the amount of space locally. Both is true for any VCS I am aware of, so this is not a TFS-specific issue.

What is a version control system? How is Git useful?
I am new to Ruby on Rails platform, and so this may sound a little naive.
Why and when do we store our work in a version control system like git?
I mean what is the advantage of it ! Can't we just keep it in our local machine ?
Advantages for using git/source control:
For yourself
Remembering what you have coded and when you did it
Being able to compare what you did to previous work
Allow you to work on something experimental, and if it doesn't work switch it back to where it was before
Working with a team
It makes working with others easier - you can work on the same file at the same time and really easily combine your changes.
It will allow you to work in multiple locations and easily have the most recent code
It will help in deploying your code to a server
Git workflow for teams
Git branching model
When to store or commit your work:
You want to do this each time you finish on a particular "idea" or piece of work you are working on. This means you can have a useful commit message and can go back im time to that feature you just wrote or that bug that you just fixed.
How often and when to commit
Reasons for using Git over other source control
Its fast (switching branches is really fast and you have a local copy, so you dont have to communicate to a server for a lot of things unless you want to push or pull changes to the server)
Yes, this seems quite naive, but every question is worth asking!
First of all, using a SCM (software configuration manager) will greatly help you in a number of scenarios:
trying out experimental features without touching the main code
developing several independent ideas at the same time
recovering from failed changes, whenever they are complex and include changes in multiple files.
tracking the exact code used in a specific release, to fix a reported bug.
This doesn't even start to touch the infinite amount of work you'd have if working in a team without SCM.
And using a SCM doesn't involve network, git and any other distributed SCM is equally valid for local development, as the repository is all in your computer. You just don't pull and push.
The choice is not whether to store code in version control versus storing it on your local machine. In fact, unlike other version control systems (like Subversion, known also as svn), Git does not need a server to run.
Version control makes it easy to understand what changes were made, view and restore older versions of files, and even import changes from one version to another.
RETRIEVAL: Imagine you are working on a project on your own. You delete an old file you don't think you need anymore. A week later, you realize that the file was very important. If you use version control, you can see what the file looked like just before you deleted it, and restore it as if it were never deleted. Also, most changes committed to version control contain messages; if you join a team and the previous developer used version control (with good commit messages) you can get an easier context for when changes were made and why.
MULTIPLE RELEASES (BRANCHES): Now imagine that your software is version 1.0. You're busy working on version 2.0, but someone files a bug. What can you do? With version control, you can zoom back to version 1.0, make some changes, and then create version 1.0.1. Most version control platforms even let you apply the changes made in version 1.0.1 onto the work you're doing in version 2.0.
MULTIPLE FEATURES: Your software is so successful, you start releasing it weekly. However, not every feature is ready for release. First you start working on the widget feature, than you start working on the doodad feature. If you work on both of these at the same time, you may have two half-coded features in development at the same time, and nothing is working well enough to release. With version control, once one of the features is done, you can merge it into the "main" release as if you wrote it in one day.
COLLABORATION: Finally, now imagine that you're in a team of five or six developers all working on the same code. Naturally, you don't want to email zip files of code back and forth, especially when every developer is working on a separate feature. With version control, you can have a single history, to which all of your developers write and read.
Naturally, some of the above can be done by keeping multiple copies of the same files in different adjacent directories. The benefit of version control software is that it can handle much of the work for you while avoiding duplicating the same file over and over on your disk.
Long winded--sorry--but hope that helps!
Advantages of using git:
Code will be safe in remote repo, even if the local project crashes
You can try out new things without worrying about previous works as they can retrieved
The code can accessed from anywhere in the world
When working in team, all the work will be stored in a single place so that it will be accessible to everybody in your team
Each and every change can be tracked easily, who did it and when they did it
Deployment of application will more easier
You can have multiple versions/branches so that it will be easy for you to identify the new features added to the application in every version

I'm finding that a number of my changes are being 'lost' when our contractor performs a check-in.
The general process is as follows:
I perform some bug analysis and implement a fix.
I then check-in my code.
The contractor performs a check-out/check-in at a later date.
The changes from the previous changeset (my changes) are lost.
In my view, this is pretty unacceptable, particularly when I'm dealing with application-breaking regressions introduced since the last build.
This has happened at least twice now, and the only thing I can think of is that the contractor is failing to ensure that he has the latest changeset at check-out. Our repo does not allow multiple check-out, and forces get latest on checkout, which makes things so weird (seeing as we both should be working with Server workspaces).
Could there be any other cause of this problem? I don't want to take my concerns to my line manager without being sure I've covered all bases.
Get Latest item on check out is set in the client and not in the repo, which means that your contractor may still be able to checkout the wrong version. They should get merge conflicts upon doing so, but that depends on where they edit (and how they manage such conflicts).
I've seen TFS lose changes this way. I have yesterday gone to a client site, made changes, checked in, today come back to my office, got the changes (assuming it will merge with my local changes like it usually does), gone to check in just now and I can see in the diff that it's wiped out the client-site changes (obviously ignoring the merge locally). I checked in just to confirm what I was seeing and yes there was no resolve conflict needed, TFS thought everything was ok, but my modified local file just blatantly overwrote the modified version in TFS effectively discarding the whole client-site change (just like if I'd chosen resolve conflict keep mine - however it never asked me about the conflict or suggested that there was one, just silently lost it)
If you eye-ball the changes before committing you can see that the changes you are making are more than you thought - i.e. the client site changes are effectively being removed and will show as differences - however it's easy to miss this when you are doing it a lot.
I had previously thought to blame coworkers when they skip out my changes this way, but now I've actually seen myself do this to myself I realise the tool is deficient. Hard to believe but there is obviously something wrong with the way it merges your locally changed file against the 'get latest'. I'm using a cloud TFS with a flaky network connection sometimes - I'm told this contributes to the issue.
I've used TFS for about 18 months now and I'm really not excited about it. It seems like the worst of the current versions of SCMs on the market.
I think this thread will help people decide if TFS is for them vs. other source control systems. While TFS does a lot more than that, I think that source control is so critical to software development that any system (or combination thereof) that you pick needs to consider source control first.
What are the good things about TFS vs. other source controls -- what does it do well that no one else does?
What are the things that TFS is bad at that everyone else seems to do just fine?
Pros
Fundamentally it's a sound system. Robust and reliable.
Integrated with work items, reporting, etc.
The power tools are really good.
[edit] It is improving, and has taken good jumps forwards with 2010, 2012, 2013
TFS is highly accessible for custom tools. There's a rich API that makes it so easy to write dashboards and other tools to get at the data in TFS. And as all the data is stored in SQL, you can browse it and query it directly if need be. I've worked with many different SCMs over the years and have never found one that is so open and accessible - everything (user stories, tasks, bugs, issues, test plans, iterations, source code control & branches, builds, unit testing, continuous integration) is just there at your fingertips. This is an awesome feature of TFS. A lot of the UI failings of TFS have been addressed in a few afternoons writing tools and a dashboard for my team to use. And let's face it, if you write your own, it does exactly what you need.
Cons
There is one area where the robustness fails miserably: If you apply several changes to a file (add, rename, edit) in "one go" it gets horribly confused. If you don't check in these actions separately, both TFS2005 and TFS2008 crash when you go to merge those changes across branches. In 2010 onwards it no longer crashes, but it often doesn't correctly check in the changes, so you have to go in and clean up a mess of missing and incorrectly named files.
There is no standalone source control browser. It's integrated into VS, which is really annoying when you want to just work on source control items without needing to run up another copy of VS. Of course, you can give your artist a Team Explorer, but let's ask ourselves if an artist who only ever wants to view the files, check out, check in, and GLV really needs a fully blown complicated VSTS instance running to achieve it? In addition, the integration is so poor that you can't realistically use TFS from the Solution explorer (it simply lies about what you have checked out, and is so unreliable when you apply actions from that window that you soon learn to open the source control window and work in there, which defeats the point of it being integrated in the first place) [edit: The file explorer extension is excellent - close to a standalone browser - and is simple and easy to use. The main drawback of it is lack of proper integration with file commands - to rename or delete files you must remember to use the TFS submenu, or you will rename/delete locally and this screws up source control completely as TFS knows nothing of the changes you have made. This unfortunately means that only 'advanced' TFS users can be trusted to use it. So, essentially, it's still a case of "no stand alone browser" for most users]
The user interface sucks (but is improving, at least on the web-access side). Sure, it works, but there is so much that could be done to make it efficient, pleasant, and more foolproof to use. e.g. [prior to 2012] When you click "check in" it ticks all remaining un-checked-in items so that if you accidentally click Check in again in future, it checks in a load of stuff you didn't want to. And after this, it would be so easy to supply an "undo last checkin" option to quickly roll it back - but there isn't one. [Edit: The UI is improved, but these specific problems are still present in VS2010, although it does now have a check-in confirmation dialog that reduces the risk of accidental checkins][edit: in 2012 it's much better, but they've gone mad and rolled all the separate TFS dialogs into a single window, which was a serious step backwards. The pending changes window doesn't work nearly as well as in 2010 - it is harder to find things, it takes more clicks to achieve the same things, and if you check in a file from anywhere all the currently 'included' files get chucked into 'excluded' so if you have several things on the go they all get mixed together]
Workspaces. In most cases, every team member has to have essentially the same workspace mapping, slaved off a local root folder. We need 7 mappings defined, which takes about 5 minutes to set up. There is no way to push the workspace definition from the server. There is no [edit]easy[/edit] way to duplicate a workspace so you can use an existing one (or another users one) as a starting point. No, you have to manually re-enter all the bindings over and over and over and over. If you change your active workspace in the source control explorer, it doesn't get synced to your pending changes window, so you spend 15 minutes wondering why the file you merged from your other branch just isn't listed. [edit: This is getting better with 2010/2012, as you can see workspaces on other PCs and copy and paste them more easily, but it's still a pretty clumsy UI]
It has changesets, but you can't bundle items into separate changesets in your pending checkins list as you can in Perforce, you can only associate them with a changeset by actually checking them in. You can really only work on one changeset at a time, or you have to separate the files out manually in your pending list as you go to check in. [still very poor in 2012]
The merge tools are terrible. As in: they simply don't work, and unnecessarily introduce bugs into your code if you rely on the automatic merge. These tools are just as bad as they were when I first used SourceSafe in 1994. So the first thing you have to do after buying a very costly VSTS licence is replace the merge tools with something that actually works. And that means that every time you get a merge conflict, you must select each file. Choose to resolve the conflict and ok. Choose to use your 3rd party merge tool and ok. Then merge. Then save. Then choose to accept your merged changes. (You should be able to choose "automatic merge" and have it simply use the third party merge tool that actually works without hitting you with a barrage of pointless and annoying dialogs that always default to the wrong option) [Edit: InVS2010 the merge tools are still awful. But the front-end UI is much improved (merging a conflict now takes a single click rather than 4 or 5 clicks - a massive improvement when you have to merge many files][In 2012 there have been further improvements, but they are still 'ok' rather than good]
It doesn't sync between running instances of VS. So if you check in a file in one VS, another one will still list that file in your pending checkins. (it's clearly easy to sync it because any changes made by the power tools windows-explorer extension are reflected in VS instantly). [Edit: In 2012 they have fixed this problem. Now every time you switch to the pending changes view it spends 15 seconds refreshing (in 2010 it cached it and showed it instantly but it was occasionally out of date)]
Branching is the standard way of working these days. So you'd expect the branch/merge tools to make this quick and easy. But no. [edit: Big improvements were made in 2010 and 2012, but merging is terribly supported - it is really labour intensive. Just little things like only being able to merge a contiguous set of changes, so if you want to merge 5 changes that are not contiguous you have to do them one by one, but each time you open the dialog it starts from scratch instead of remembering where you were, what you last merged, the list of availablke changesets, etc. You should be able to select any changesets you want and it should automate the rest]
If you GLV (get latest version of) a solution, and some of the projects in it have been changed, VS repeatedly asks if you wish to reload each changed project. It is about 10x faster to close your solution, then GLV, then open the solution again than to GLV with it open. If I'm GLV'ing then of course I want to reload the projects! When I buy my food at the supermarket they don't ask me for every item "do you wish to take this item home with you?". [Edit: Still broken in VS2010][Fixed in 2012. Hurrah!]
[edit] If two team members add a new project to a solution, then when the second person goes to check in, they must (obviously) resolve a merge conflict. However, TFS treats the .sln as a text file, and corrupts it (it adds the two project entries but the project count is effectively only incremented once). It would be so easy to fix the sln format to make the files mergeable.
[edit] I don't do any source control operations from within the Solution Explorer window, as it has been rather unreliable ever since "integration" first came along. Even in 2008 it usually has random "checked out" icons on files that are not checked out, and recursive operations sometimes do weird things. Almost every source control 'glitch' we have is a result of someone starting an operation from the Solution Explorer. Luckily, I prefer to work in a Source Control window anyway.[2012: Sorry, can't tell you if this is fixed, as I haven't used this feature since 2008]
[edit] Where to start with the Source Control Bindings window? VS could say "Your Source Control settings have been corrupted again for no obvious reason. I never could get the hang of Thursdays. Shall I fix this for you? [YES]", but instead, it shows a complicated, confusing dialog full of information that makes no sense to anybody, resulting in a UI so scary that it makes junior programmers soil themselves. The trick is to ignore the whole window, hide behind your desk and click the "fix it" button, and it fixes it.
[edit - added 12/2010] When you Get source code, especially when resolving merge conflicts, other windows are often brought to the front (either the Solution Explorer jumps in front of my Pending Changes view, which I have docked in the same tabbed area, or the Source Control window vanishes behind another document window. This is really annoying when you have another file to merge or another folder to Get, as you have to keep "finding" the Source Control/Pending Changes windows. Getting code should not constantly reorder my document/tool windows.[2012: Still broken]
[edit - added 1/2014] With TFS 2012/2013, there is a choice of Server or Local workspaces. Server is the name for the old system where you must be online with the server to check files out. Local is the new default and makes a copy of the entire source repository on your computer, allowing you to make edits to any files without needing to check them out first. TFS then diffs your files against its local copy to work out what you changed. This sounds good, and for many people it probably is good, but it has some serious drawbacks that you should be aware of:
As you no longer check out files, they do not get locked when you edit them, and thus several people can edit any given file simultaneously, requiring a merge operation when they check in. This is fine for text-based source code files, but results in difficult situations or lost work when the files are unmergeable. Unmergeable or non-automatically mergeable files include Solution, Project, Resource (resx), XAML and any other XML files - so this causes a lot of problems in a development environment. If (like us) you also want to store Word and Excel documents and binary files under source control, local workspaces are positively dangerous. We have lost several days of work because someone unwittingly used a local workspace and then it was not practicable to merge their changes. You can reconfigure the TFS server to make Server workspaces the default to defend against this.
With Local workspaces you have to keep two copies of everything on your computer. When we upgraded TFS we suddenly found everyone lost 25GB of disk space, and it took several weeks to work out where the disk space had gone! This was a major problem for us because we all use SSDs and it is only now (2014) that SSDs are getting large/cheap enough that we can afford to be so inefficient with our disk space.
In the few weeks that we used local workspaces we had several incidents where TFS corrupted files or lost changes, presumably due to bugs in the implementation. Quite simply, we cannot accept anything less than 100% reliability for our source control system.
TFS is getting much easier to manage; these days if you don't want to customise anything too much you can set up a server in a very short time (hours) and setting up continuous integration builds and backups etc is extremely easy. On the flip side, while I found it very easy to set up backups of a TFS database, restoring that database and getting up and running after our server bricked itself was another matter - it took 4 days to work through all the unnecessary blocking problems (e.g. you have to restore the backup form a network drive, the data can't be local. When I tried to restore the image to the rebuilt server, TFS kept telling me there were no databases that could be restored. When I got past that, TFS wouldn't use the databases because they didn't match the host server (because that server was gone, the OS had been reinstalled). It took a lot of searching and fettling to get the backup to restore. Restoring should "just work"!
As you can see, most of the above are just trivial UI gripes. There is such a lot that could be improved about the UI. But the actual underlying product is good. I prefer TFS to pretty much every other SCM I've used over the last 28 years.
I wouldn't even mind the poor UI so much, except that it is one of the core UIs developers have to use on an hour-by hour basis, and they have to pay such a lot to get it. If the subscription money from a single developer was invested on improving the UI it would make a massive difference to the usability of TFS! It's painful to think that TFS is merely good or ok when it could so easily be excellent with a bit of nice UI.
Hates
Doesn't track changes to files unless you've checked them out, so if you edit a file in Notepad++ TFS is unaware that anything changed.
It's very easy for someone to check out a fille and lock it so that nobody else can make changes. TFS shouldn't drop this ability, but it certainly should make it much harder to do than it is currently.
The methods to undo a commit or two is very unclear, so much so that I'm never quite sure if it worked or not.
The way that TFS makes files read only unless you check them out is obnoxious, though it does help me remember to check files out before I save the edits I've made.
Loves
I suppose built-in integration with visual studio is nice, if you like that kind of thing (I don't)
I am a member of the Team Foundation Server team at Microsoft. There are a lot of very valid issues raised here. Some of them are addressed in the 2010 release. Others remain as issues, but we do recognize them and are working to improve the developer experience with the next release. Discussions like this are great for helping us make sure we're solving the right problems.
Here is some info on issues that are at least partially addressed today in the 2010 version:
Stand alone client
For non-developer customers that want to use the product outside of VS, they can use the Windows Shell extension powertool.
If you have users (developers or not) that need to access TFS from non-Window machines, they can use Team Explorer Everywhere. This is supported on platforms including Mac & Linux.
Copy workspace
There are two ways to copy a workspace today. The 1st is by using the workspace template command at the cmd line. Ex.
Tf /workspace /new /template[workspace name/owner to copy from]
Alternatively, you can open a workspace in the UI, select all of the mappings, copy them, & then paste them into a file/email. Someone else can than paste those same mappings into their workspace.
It would definetly be great if you could simply specify a default workspace that clients automatically pick up, but we don't have this today.
Merging robustness
The scenario described where you do an add, rename, add & then have problems when you merge has been addressed in TFS 2010.
Branch/Merge as a 1st class experience
In TFS 2010, branches are now 1st class objects in TFS. You can visualize your branches & even track changes as they move through the branch. Branching is also now a fast server based operation.
Get Latest Version of multiple projects
You can do this today by choosing the TFS instance node in source control explorer & then selecting get latest. This is the equivalent of the root folder ($).
File locking
By default TFS never locks files when users checks them out. This is the way we use TFS at Microsoft & how we see the majority of our customers using TFS. It is possible to enable users to explicitly lock files. Some customers find this desirable, but it is not the default path experience.
Con: Checkout model. Many applications do not deal well with files that are marked as read-only then change to writable (Word 2007, Notepad). So you open a file, edit the file, try to save then you're told that you can't save because it's read-only. Great, now you have to Save As..., delete the original and renamed the new one to the old name. If there's an upside to having local files be read-only I don't see it. I really prefer Subversion's approach to this.
The one upside to making files read-only is that it reminds you to check them out. However that's really just a symptom of the check-out model.
I think that TFS is the single best ALM product on the market today. Looking at it from only a source control platform is slanted. I have used many products in my career to date: VSS, SVN, Git, StarTeam, CC/Harvest, and ClearCase - apart from TFS. Personally, I cringe at the thought of going back to anything other than TFS.
TFS is an extremely powerful platform. My biggest problem with it is often related to people not knowing how to use it or using it incorrectly. It is not meant to be an application that "just works". Sure, you can use it for basic source control without learning much about it - but if that is all you use it for, then you really are better off using one of the less robust tools out there. In reality, what TFS does not give you is the way to interpret features how you want to. It is specifically built from the ground up to support process and not just be a repository.
Con: Timestamps. There's no way to set TFS to use the remote last-modified timestamp as the local last-modified timestamp. The local file's timestamp only tells me when I got the file. If I get a file that's 2 years old, there's no way to know that based on the local timestamp.
Other source controls that I have used have this ability.
Cons:
workspace version: You can't identify the version of a workspace without doing a recursive search.
terrible offline experience. attrib -r + tfpt online shouldn't be the way to work offline. Give me something like git that allows me to track status, undo and make changes. I'm even fine if it only stores the difference between the workspace version and current.
Merging robustness: a changed file on the server + a local edit on different lines is not a conflict. a writeable file should not be an automatic conflict. The automerge button should NOT exist, because it should never be a scenario.
Workspaces: the idea of being able to rearrange the source structure is just odd, and causes issues. the requirement of having both branches mapped in order to merge is odd. The requirement of having to do an operation multiple times, because my workspace mapping doesn't have a true root folder is wrong.
Full reliance on remote server: There are some nice things about having all these things stored on the server, but really, you could store information locally and then upload it when needed. Keep pending changes, workspace mappings, basic undo history locally, etc.
Pros
Shelvesets: I love these, and wish support for them was brought to the local disk as well (think git stash)
Source control view in VS: It's pretty cool to be able to view the entire repository without downloading it. There are some usability issues, but the overall idea is cool.
Workspaces: yep, both places. While re-arranging a repo is odd, the ability to only download what you need is pretty awesome. I often wish I could choose a root folder and then check box the paths I need, but oh well.
Dislikes:
Using the history to figure out what has been done is cumbersome to say the least. You have to click on every single history entry to see what files were changed, and then you need to go through a context menu to get a diff.
Working while disconnected from the network is a big no-no. Ever heard of working on an airplane?
No Windows Explorer integration for when you work with files outside of VS (think TortoiseSVN).
Process methodologists (configuration managers) love to not allow shared check-outs. This is absolutely horrible for example for config files that you need to modify for testing.
SC gets confused with complex move/delete operations.
SC does not recognize when a checked out file has not changed. For example, service reference updates check out all related files and often regenerate the exact same content. These files should implicitly be removed from check-ins because they just add noise when you look at your changeset later.

Shelving.
Anybody guessed which is my favorite SCM system? SVN + TortoiseSVN + VisualSVN :-)
Search functionality is not implemented in TFS 2010 ?
VSS we have search in file; TFS 2008 we have search file ...
Con: If you want to move multiple files to a subfolder of the existing location, you have to do that one at a time. Wow, that's horrible.
The lack of rollback has been my biggest pain point.
The lack of true rollback support and the inability to rename a TFS Project are my two main pet peeves with TFS. Other than that, I've been very happy with it for 2-3 years.
The fact that certain applications do not support in-edit changes from read-only to writable (forcing you to reopen the file in question) is annoying but is really a problem with those specific applications. The fact that a file is read-only while not checked out has certain uses, one of which being that it reminds you to check out the file. It does occasionally, however, lead to confusion when trying to get specific revisions of files. Writable files are not re-downloaded unless you enable a flag, because they're considered local edits.
