TFS: "Get This Version" vs "Rollback Entire Changeset" - tfs

I find myself needing to remote debug some deployed code, I have a clear changeset defined in tfs that is the code that was deployed.
My question is: What is the standard procedure in TFS to ensure my local code matches what has been deployed to live.
"Get This Version": I seem to recall that operation only checks out the changeset in question, leaving all other files in place, some of which have have been changed by another later changeset
"Rollback Entire Changeset": This one appears most promising, but I'm confused if it means 'Roll back TO this changeset', or if it means 'Roll back this changeset' effectively leaving the code in a state BEFORE that changeset was checked it.
Any clarification would be greatly appreciated.

According to your description, you shouldn't use rollback entire changeset feature. This will influence your source control in TFS. If you roll back a file to an earlier version, tfs will eliminating the effect of all changesets that occurred after that version. More details please take a look at this tutorial: Roll back changesets
Actually you just want to get an older version in history include all files for a branch or root project folder.
In TFS, you could Get Specific Version instead of get latest version of the branch. Details please refer this question: TFS Get Specific Version into separate folder
How to do this in VS: right click the branch-Advance-Get Specific Version. Have a look at my answer in this similar question: TFS source code explorer: browse specific revision

How to get the files that were changed in a changeset in tfs

I was looking through a changeset in tfs and it has more than 6000 files in changeset but when I check the files individually almost each file included in changeset was indentical to the previous version. Is there a way I can find what files were really changed through the changeset in tfs?
this is an old one, see this post. you have to be a little bit brave, so try it somewhere safe first.
specifically:
Another option is to “Undo Checkout” all the changes, and clicking “No to All” when asked to confirm for undo checkout. This way Visual Studio will “undo checkout” all the files that are not changed, and all the changed files will remain checked out. I always use this method.

check out TFS at a specific change set

I'm using TFS and VS 2012 and my project is in a broken state and I can't figure out why. I'd like to go back to a previous version of my solution when I know it worked and make changes on that working version. However, when I choose to check out a specific changeset, it seems to me like it's only changing the files that were changed in that changeset. When I use git and check out a revision, my code looks exactly like it did at that revision. Files that didn't yet exist at that revision are removed, files that did exist have contents as they were at that revision, etc. But I can't seem to do the same in TFS. I can't figure out how to get all of the files (and only the files) in the state that they existed when a particular changeset was checked in. Am I missing something? Any help REALLY appreciated.
Try using the Advanced option when you right click on a solution or folder in Source Control:
Then when the dialog appears, check both check boxes so the version you have is overwritten with the specific version you want by selecting Changeset from the ddl and entering the changeset you are after...
This should overwrite the existing solution files with the specific version.
If you have trouble doing it over top of existing files, delete the source on your local machine first and get the specific version after that.
A changeset is just the files checked in at one time, not a snapshot of the whole system. You want to use labels for that. A label will mark all the files in their present state, just as you describe Git doing.
Find the changeset you want and "Get This Version" to only get the changed files.
Manually check out each file for edit in Source Control Explorer to match the changeset.
Now the previous changeset's edits can be checked in.
NOTE: This is MUCH quicker than getting the entire repo using "Get Specific Version."

Team Foundation Server - TF Get with changeset number

I'm trying to write a very lightweight "build" script which will basically just get a few files from TF (based on a Changeset number). Then I'll run those files in SQLCMD.
I'm using this:
tf.exe get c:\tfs\ /version:c2681 /force /recursive
However, this appears to get EVERYTHING, not just the files in changeset #2681. I'd like to be able to point it to the root of my tfs workspace, give it a changeset number, and have it just update those few specific files. Also, it appears to be getting older versions (perhaps what was current when changeset #2681 was checked in)?
Is there a way to get just those specific files, WITHOUT needing to call them out specifically in the tf get itemspec?
EDIT: I actually had to add the /force option in order for it to do anything at all. Without force, it doesn't appear to even retrieve from the server a file I deleted locally, that's definitely in the changeset.
thanks,
Sylvia
Everything mentioned in Jason's and Richard's posts above is correct but I would like to add one thing that may help you. The TFS team ships a set of useful tools separate from VS known as the "Team Foundation Power Tools". One of the Power Tools is an additional command line utility known as tfpt.exe. tfpt.exe contains a "getcs" command which is equivalent to "get changeset" which seems to be exactly what you are looking for.
If you have VS 2010, then you can download the tools here. If you have an older version, a bing :) search should help you find the correct version of the tools. If you want to read more about the getcs command, check out Buck Hodges's post here.
The TFS server keeps track of what each workspace contains1. Any changes made locally with non-TFS client commands (whether tf.exe, Team Explorer or another client) will lead to differences between the TFS Server's view and what actually exist.
The force options on the various clients just gets everything removing such inconsistencies (effectively resetting both what is on the client and what the server thinks is there).
When you perform a get against a specified version (whether date, changeset or label) you get everything up to and including that point in time, whether on not specifically changed at that point. So getting
tf get /version:D2012-03-30
will get changes made on or before that date.
To get only the items included in a changeset you'll have to do some work yourself, using a command to get a listing of the content of a changeset and parse that to perform the right actions (a changeset can include more than just updates and adds of files2).
It seems to me that if you want to perform a build at each changeset affecting a particular TFS folder you would be better off looking at using TFS Build which is all about doing exactly that – avoid reinventing the wheel – and focus on the build part (other continuous build solutions are available).
1 This will change with TFS11 local workspaces.
2 Eg. handing the rename of a folder will take some non-trivial work.
The command will get all the sources for the given changeset. By default it will only get the files that it thinks are different between your workspace and the server. However, by using the /force option you are asking it to get everything regardless of the state it thinks your workspace is in (which is much slower but has the benefit of ensuring your workspace is fully in sync with the server).
So just removing /force will probably achieve what you want.
edit
As I said above, tfs will get all files that it thinks are different from the server. If you manually delete a file from your local workspace, TFS won't know that it is missing from your local version, so it won't think it needs to update the file. There are three solutions to this:
Use /force to make sure things are in sync, and put up with it being very slow.
Don't modify files in your workspace with anything other than TFS tools (tf.exe, Visual Studio, TFS power tool for the explorer shell). You shouldn't just delete files on your local hard drive - if they really need to be deleted, then delete them in source control.
Go offline in TFS before you make changes manually. Then when you go online, TFS will search for all the changes you have made and add them to your pending changes so that TFS is aware of them.

Lost at least one changeset in TFS - Now won't check in changes to file involved, what to do?

We've lost at least one changeset in TFS (we don't know yet if there's more, could be none). We noticed a changeset that was at the top of the list is now gone. We think there might be two at least because the symptoms below also exists for at least one other file we've discovered. Additionally, we can see a hole in the changeset numbering sequence, and we don't believe the changeset with the file described below is that one.
The single file involved had one line changed, and the version in TFS has the file before the change.
Doing a get latest or get specific version gives me the old file, before the change.
After doing the "Get specific version", in Source Explorer, in the column that shows workspace status, it says "No" indicating that the file is outdated. Nothing I've tried so far gives me the file with the change that was checked in.
If I try to view the file from the Source Explorer, it says my file is out of date and asks if I want to view the server version or the workspace version. Selecting the workspace version gives me the file before the change (probably because I did the get specific version above), selecting the server version gives me nothing, dialog just goes away.
If I check out the file, and redo the change, and try to check in, it says that a newer version exists on the server and asks me how to resolve. I can pick discard local changes or discard server changes. Since I want to check in my changes, I select to discard the server changes, but when I try to check in again (conflicts in TFS stops the checkin process), it just repeats the conflict and asks what to do.
Basically:
Changeset is gone, verified with the developer that checked it in
File does not have the change on the server
Server is confused regarding version of this file, complains about outdated version if I try to view it
Won't let me check in changes, just repeats a conflict with a newer version, presumably the file the developer checked in that for some reason is no longer available through a changeset
So... anyone had this problem? This is TFS 2008 with everything I know of updates applied, including all service packs on the developer machines, running Visual Studio 2008 Professional with Team Explorer 2008.
What do I do? Is my only recourse reverting to the nightly backup?
Edit: Things I'm trying after posting the question:
Checking disk space on server hosting the SQL Server (same as the TFS server): Plenty, 6GB free on one disk and 9GB free on another. Perhaps not plenty enough for the future, but easy to increase (virtual machines), but should not have anything to do with our current problem.
No change: Recreating a fresh workspace in a different folder on disk (I deleted them all before adding a new one), doing a "Get specific" version on root folder of project and checking the bottom two checkboxes (overwrite writeable and overwrite all), afterwards says that I have the latest file (Yes in that column I mentioned above). Viewing the file shows me file before the change. Doing a "Get specific" version on that particular file makes it turn to "No", same problem with checkin.
Solved??
I did another checkin on a totally different file, not including the file we had trouble with above, but that file was "attached" to that changeset, even though it was definitely not checked in by me when I tried this.
In other words, it looks like the part of the changeset that related to the file was still in TFS, with the right changeset id, so when another changeset appeared with the same id, that file became a part of it.
Has anyone experienced anything like this? It doesn't really improve my trust towards TFS if things like this can happen.
We still have another file that misbehaves, I will have to see if it has all of the same problems or not and what, if anything, we can do with that. If that file is related to the other changeset we seem to be missing, I don't think we can get that changeset into the database unless we fire up a SQL tool (which I'm really not going to do.)

Why doesn't TFS get latest get the latest?

Why Why WHY doesn't TFS's get latest work consistently?
You would have thought that feature would have been tested thoroughly.
What I have to do is, get specific version, then check both overwrite writetable files + overwrite all files.
Is my local setup messed up or you do this also?
TFS redefined what "Get Latest" does. In TFS terms, Get Latest means get the latest version of the files, but ignore the ones that the server thinks is already in your workspace. Which to me and just about everyone else on the planet is wrong.
See this link: http://blogs.microsoft.co.il/blogs/srlteam/archive/2009/04/13/how-get-latest-version-really-works.aspx
The only way to get it to do what you want is to Get Specific Version, then check both of the "Overwrite ..." boxes.
Sometimes Get specific version even checking both checkboxes won't get you the latest file. You've probably made a change to a file, and want to undo those changes by re-getting the latest version. Well... that's what Undo pending changes is for and not the purpose of Get specific version.
If in doubt:
undo pending check in on the file(s)
do a compare afterwards to make sure your file matches the expected version
run a recursive 'compare' on your whole project afterwards to see what else is different
keep an eye on pending changes window and sometimes you may need to check 'take server version' to resolve an incompatible pending change
And this one's my favorite that I just discovered :
keep an eye out in the the Output window for messages such as this :
Warning - Unable to refresh R:\TFS-PROJECTS\www.example.com\ExampleMVC\Example MVC\Example MVC.csproj because you have a pending edit.
This critical message appears in the output window. No other notifications!
Nothing in pending changes and no other dialog message telling you that the file you just requested explicitly was not retrieved! And yes - you resolve this by just running Undo pending changes and getting the file.
TFS, like some other source control providers, such as Perforce, do this, as the system knows what the last version you successfully got was, so get latest turns into "get changes since x". If you play by its rules and actually check things out before editing them, you don't confuse matters, and "get latest" really does as it says.
As you've seen, you can force it to reassess everything, which has a much greater bandwidth usage, but behaves closer to how SourceSafe used to.
It's hard to respond to a statement without examples of how it's not working, but it's crucial to understand that TFVC (in "Server Workspace" mode, which was the mechanism prior to TFS 2012) does not examine the state of your local filesystem. TFVC Server Workspaces are a "checkout-edit-checkin" type of system where this is by-design, an intentional decision made to massively reduce the amount of file I/O required to determine the state of your workspace. Instead, the workspace information is saved on the server.
This allows TFVC Server Workspaces to scale to very large codebases very efficiently. If you are in a multi-gigabyte code base (like Visual Studio or the Windows source tree) then your client does not need to scan your local filesystem, looking for files that may have changed, because the contract you have with TFS is that you will explicitly check a file out when you want to edit it.
You are expected to not mark a file as write-only and change it without explicitly checking it out first. If you go down this route, then the server does not know that you have made changes to your file, and performing a "Get Latest" operation will not update your local workspace, because you haven't told the server that you've made changes.
If you do subvert this mechanism then you can use the tfpt reconcile command to examine your local workspace for changes that you have made locally.
If you find yourself using "Get Specific Version" and selecting the "force" and "overwrite" options, then it is very likely that you are in the habit of bypassing all of the enforcements that TFS has implemented to keep you from hurting yourself, and you should probably consider TFVC Local Workspaces.
TFVC Local Workspaces provide an "edit-merge-commit" type of version control system, which means that you do not need to explicitly check files out before editing them and they are not read-only on-disk. Instead, you simply need to edit the file, and your client will scan the filesystem, notice the change, and present this as a pending change.
TFVC Local Workspaces are recommended for small projects that do not require fine-grained permissions control, since they present a much nicer workflow. You are not required to be online, and you do not have to explicitly check files out before editing them.
TFVC Local Workspaces are the default in TFS 2012, and if they are not enabled for you, then you should ask your server administrator. (Organizations with very large codebases or strict auditing requirements may disable TFVC Local Workspaces.)
Eric Sink's excellent book Version Control By Example outlines the differences between checkout-edit-checkin and edit-merge-commit systems and when one is more appropriate than the other.
The Professional Team Foundation Server 2013 book also provides excellent information about the differences between TFVC Server Workspaces and TFVC Local Workspaces. The MSDN documentation and blogs also provide detailed information:
Decide between using a local or a server workspace
Server workspaces vs. local workspaces
Team Foundation Server – Trying to understand Server versus Local Workspaces
Team Foundation Server (TFS) keeps track of its local copy in a hidden directory called $TF.When you issue the "get Latest Version", TFS looks into this folder and see weather I have the latest copy or not. If it does it will not download the latest copy. It does not matter if you have the original file or not. In fact you might have deleted the entire folder (as in my case) and TFS won't fetch the latest copy because it does not look into the actual file but the hidden directory where it records changes. The flaw with this design is, anything done outside the system will not be recorded in TFS. For example, you may go into Windows explorer, delete a folder or file and TFS wont recognize it. It will be totally blind. At least I would expect there Windows would not let you delete this file but it does!
One way to enforce the latest copy is to delete the hidden $TF folder manually. To do that, go to command prompt and navigate to the root folder where you project was checked out and issue this command
rd/s $tf // remove $TF folder and everything inside it
If you want to just check the hidden folder, you can do it using
dir /ah // display hidden files and folders
Note: If you do it, the tf will think you do not have any local copy even though you have it in files and it will sync up everything again.
Caution: Use this method at your own risk. Please do not use it on critical work.
"Get latest version" by default will only download the files that have changed on the server since the last time you ran "Get latest version". TFS keeps track of the files you download so it doesn't spend time downloading the same version of the files again. If you are modifying the files outside of Visual Studio, this can cause the consistency problems it sounds like you are seeing.
Unfortunately, there has to be one or more bugs in TFS 2008, since this problem regularly crop up on developer machines and build servers where I work as well.
I can do Get Latest, I can see in the history list of the project that there have been commits after I last did a Get Latest, I have not touched the files on disk in any way, but after the "Get Latest" function has completed, when I check the TFS tab, some of the files still says that they're not the latest version.
Obviously TFS is able to determine that I have old files locally, since the list says so. Yet, Get Latest fails to do that, get the latest version. If I do what you did, use the Get Specific version, and check the two checkboxes at the bottom of the dialog, then the files are retrieved.
We changed our build servers to always use the Get Specific version type of function instead, so this part now works, but since our build server (TeamCity) also relies on checking if there have been changes to the files in order to kick off a build, sometimes it lapses into a "nothing changed, nothing to see here, move along" mode and does nothing until we forcibly run the build configuration.
Note that I have experienced this problem on a machine that is never touched, except for get latest + build, both manually, so there's nothing tampering with the files. It's just TFS getting confused.
One time this cropped up I verified that the files on disk was indeed binary identical to the version previously retrieved, so no manual tampering had been done with the files.
Also, I fail to see how TFS can "know" whether files have changed on disk or not without actually looking at the contents. If one part of TFS can see that the files are indeed not the latest version, then the Get Latest version should absolutely be able to get the latest version. This in reference to comments to other answers here.
It might because you are login TFS as the same user, and the workspace name (based on machine name by default) is also the same, so TFS thinks your are on the same machine and same workspace, thus you already have the latest version of the files, so it wont get them for you.
try rename your machine, and create a new workspace as a new machine.
Go with right click: Advanced > Get Specific Version. Select "Letest Version" and now, important, mark two checks:
The checks are:
Overwrite writeable files that are not checked
Overwrite all files even if the local version matches the specified version
WHen I run into this problem with it not getting latest and version mismatches I first do a "Get Specific Version" set it to changeset and put in 1. This will then remove all the files from your local workspace (for that project, folder, file, etc) and it will also have TFS update so that it knows you now have NO VERSION DOWNLOADED. You can then do a "Get Latest" and viola, you will actually have the latest
I had the same issue with Visual Studio 2012. No matter what I did, it didn't get the code from TFS source control.
In my case, the cause was mappings a folder + subfolder from the source control separately but to the same tree in my local HD.
The solution was removing the subfolder mapping using the "manage workspaces" window.
Most of the issues I've seen with developers complaining that Get Latest doesn't do what they expect stem from the fact that they're performing a Get Latest from Solution Explorer rather than from Source Control Explorer. Solution Explorer only gets the files that are part of the solution and ignores anything that may be required by files within the solution, and therefore part of source control, whereas Source Control explorer compares your local workspace against the repository on the server to determine which files are needed.
It could happen when you use TFS from two different machines with the same account, if so you should compare to see changed files and check out them then get latest then undo pending changes to remove checkout
This worked for me:
1. Exit Visual Studio
2. Open a command window and navigate to the folder: "%localappdata%\Local\Microsoft\Team Foundation\"
3. Navigate to the sub folders for every version and delete the sub folder "cache" and its contents
4. Restart Visual Studio and connect to TFS.
5. Test the Get Latest Version.
In my case, Get specific version, even checking both check boxes and undoing all pending changes didn't work.
Checked the work spaces. Edit current workspace. Check all paths.
The solution path was incorrect and was pointing to a deleted folder.
Fixed the path and get latest worked fine.
Every time this happens to me (so far) is because I have local edits pending on the .csproj project file. That file seems to keep a list of all the files included in the project. Any new files added by somebody else are "not downloaded" because they are not in my locally edited (now stale) project file. To get all the files I first have to undo pending changes to the .csproj file first then "get all". I do not have to undo other changes I have made, but I may have to go back and include my new files again (and then the next guy gets the same problem when he tries to "get all"...)
It seems to me there is some fundamental kludginess when multiple people are adding new files at the same time.
(this is in .Net Framework projects, maybe the other frameworks like Core behave differently)
just want to add TFS MSBuild does not support special characters on folders i.e. "#"
i had experienced in the past where one of our project folders named as External#Project1
we created a TFS Build definition to run a custom msbuild file then the workspace folder is not getting any contents at the External#Project1 folder during workspace get latest. It seems that tfs get is failing but does not show any error.
after some trial and error and renaming the folder to _Project1. voila we got files on the the folder (_Project1).
Tool:
TFS Power Tools
Source:
http://dennymichael.net/2013/03/19/tfs-scorch/
Command:
tfpt scorch /recursive /deletes C:\LocationOfWorkspaceOrFolder
This will bring up a dialog box that will ask you to Delete or Download a list of files. Select or Unselect the files accordingly and press ok. Appearance in Grid (CheckBox, FileName, FileAction, FilePath)
Cause:
TFS will only compare against items in the workspace. If alterations were made outside of the workspace TFS will be unaware of them.
Hopefully someone finds this useful. I found this post after deleting a handful of folders in varying locations. Not remembering which folders I deleted excluded the usual Force Get/Replace option I would have used.
I encountered the same problem:
My development server was corrupted and restored, but the information restored was from a few days ago.
TFS was updated that all the files are up to date, but in practice my files were correct a few days ago!
Nothing I did helped. get latest did not get the latest version.
At the end I got specific varision from a month ago. my files were updated accordingly, and then I did get latest.
And it worked. the files have been updated.
