Why is TFS asking to resolve conflict after get specific version - tfs

I am downloading a specific version of a branch but keep getting prompted to resolve conflicts after the download is complete.
Before I call get specific version, the state of the branch is "not downloaded", I confirmed this with file explorer, the folder does not exit locally .
I have also checked Overwrite writable files that are not checked out and Overwrite all files even if that local version matches the specific version in the get specific version Get dialog.
If no local files existed before the call to get specific version what is the server version conflicting with?
Surly any conflicts would have been resolved when that change set was initially commit-ed, the change set cannot be in a conflicted state on the server?

Removing the mapping from the root directory and then adding it back again solved this. There must have been a conflict between the actual files and what VS thought was there.
Still don't know why it would try to merge in that situation though. Surly the state of the actual folder should take prescience over whatever VS thought was in there.

What do all the options on GetOptions mean?

The MSDN documentation lists four options, with limited explanation:
Overwrite "Overwrite existing writable files if they conflict with the downloaded files." Does this apply to all files, or just ones we've told TFS we've edited?
GetAll "Gets all files." What files does TFS not normally get?
Preview "Executes a get without modifying the disk." This one seems pretty clear.
Remap "Remaps existing items on the disk to the server items where the content and disk location are not changing." I have no idea what this means.
Overwrite: will blindly overwrite writable files that you have not pended for edit. If you have marked a file as 'writable' then you have violated the contract with TFS and it assumes that you have done this for a good reason (eg, modifying the file without taking a checkout, because you were working offline). This will generally produce a writable conflict on the file, but if you specify this flag, then the writable file will be overwritten.
This only applies to server workspaces (local workspaces are always writable). This has no effect on files that you have pended for edit. Get will always produce conflicts for files that are edited locally and updated on the server; if you want to update files that are checked out, you must undo the checkout (or resolve the conflict with TakeTheirs).
Get All: will download every file and update it, even if TFS believes that the local version is the same as the remote version and that downloading a new version would be a noop. TFS tracks every version that you have locally, as well as remotely, so this is only useful if you edit files locally without checking them out.
If you have kept them writable, then then - as mentioned above - this will be a writable conflict. If you have then marked them read-only then TFS assumes that you have not made any changes and will not bother updating them when you do a get (because it knows the file contents haven't changed). If you have manually changed the file contents, then marking this will update those files to the server version.
Preview: will just fire events and provide results that indicate what would be downloaded with the given parameters.
Remap: is a clever option that allows you to perform an in-place branch switching (which is very common with some version control systems that branch at the repository level - like Git - but somewhat complicated in TFVC.)
Consider that you have mapped $/Foo/main to C:\Foo, and done a get latest. If you update your working folder mappings so that $/Foo/branches/feature now points to C:\Foo, then issue a get with Remap, then the server will download only the changed files between main and branches/feature, so it's an inexpensive way to update your local workspace to a feature branch.
(If you're looking for an example, this functionality exists in the command-line interface and in Team Explorer Everywhere but not in Visual Studio.)

TFS check in replaces files

tfsI get my some of my local files replaced with another version when I check in a new version of my project.
We use TFS 2010.
Here's the situation in more detail:
A colleague made significant and incomplete changes to the project leaving it nonfunctional, checked in that code and went on a two week vacation. Since these changes were not even required the obvious course of action is tho get the previous version and work from there.
The problem happens when I check in the new working version of the project: instead of just delivering files to the server I get files replaced on my machine with the server version. I never would have thought checking in would get files from the server!
When you check in your changes, Visual Studio will always try to merge them with the latest version on the server. It must, because the version history of each file is linear, unless you manually branch files.
If the changes on the server are incompatible with your local changes, the checkin will be blocked and you will have to resolve any conflicts locally before you can check in again.
What you're seeing is expected behavior and it cannot be different due to the way TFVC works. Your colleague should not check in a version that doesn't work. In such cases he should create a shelveset (which will store the files seperately from standard history).
In your case I'd select the checkin from your colleague, select Roll back and check in the result of that. It essentially removes his changes, but they are not lost. By re-applying the rolled back changeset (roll back the roll back changeset) or by getting the specific version with the changes he can continue working on them.

Computer renamed - TFS Workspace doesn't work now

Had to change my computername and domain. Now I can't access team foundation. I tried this statement to fix it.
tf workspaces /updateComputerName:MyOldComputerName /s:"http://MyServer/MyCollection"
It didn't work. I get the following error "Key not valid for use in specified state."
Not sure what to do now.
It sounds like you may have a problem that will prevent remapping the workspace. However, it's possible that the command isn't quite correctly formed, so try checking the collection URL (I'd expect it to include MyServer:8080), and in versions of TFS 2010 onwards the documentation refers to /collection: rather than /s:
If that fails, then one approach to rescue things is to create a new workspace and delete the old one. You can transfer any edited files you had checked out to the new workspace as follows:
Rename your old source code folder, so you keep a backup
Create a new workspace that maps the (old) source code folder location, and Get the latest version of the code.
If you think you deleted or added files, use a folder-diff utility to find them, and manually re-do those changes.
Now check out everything (right click on the root folder and check it out)
Copy your backed up source code over your workspace folder
Undo checkout on everything. Visual Studio will ask if you want to discard your changes. Carefully choose the "No to all" option. This means it will only discard locks on unchanged files.
You will now have all changed files listed in your pending changes.
Once you're absolutely sure this has all worked, you can delete your backup of the source.
(You can achieve a similar thing by unplugging your network cable to force Visual Studio to go offline, moving your old source code back in place of your new workspace folder, then plug the net cable back in and using File > Source Control > Go Online. This should diff your code to the server and work out what changed. I don't trust this as much as the above approach though)
Once you have the code in your new workspace, you can use the tf command to delete the old workspace to clean everything up.

TFS can't check in changes after replacing file

I'm re-writing an Asp.Net project that a colleague had done a prototype version of. I deleted the Default.aspx and created and new one and now I'm trying to check that new version in.
When I try to check in pending changes I get the standard:
Check In, No files checked in due to conflicting changes. Please use
Conflicts Channel to resolve conflicts and try again.
I'm re-directed to the Pending Changes - Conflicts tab, where I'm presented with the options: 'Take Server Version' or 'Keep Local Version'.
If I click 'Keep Local Version', I get the following error:
Error, The following exception was encountered. The item
$/ProjectName/Default.aspx already has pending changes.
How can I get it to accept my new version of the file?
Sounds like there's a newer version of that file on the server side. Copy your local file somewhere, then discard your changes and get latest. Then check out and overwrite the checked-out version with your local file. Perhaps there's a more elegant way to do it, but it should work - and of course it will also overwrite any changes made to the server-side version.
We've just spent 30 minutes fighting with TFS due to this problem.
A colleague had checked in a file, and we wanted to rollback to a previous version. TFS would let us check-out that file, use History, and get the older version, but as soon as we hit Save, VS2015 would immediately "un-check-out" the file, revert back to the latest version of the file in TFS and we lost our changes. No warnings, no possibilities to prevent it.
Other times, we'd do a Check-in, but TFS would complain "No files checked in due to conflicting changes", and, again, revert us back to the latest version from TFS, with no options to prevent this.
What finally worked for us was to
check out the file
set it's contents to the older version (which is what we wanted)
open the folder where it was stored and set the file to Read-Only
check in the file
By doing this, TFS didn't automatically overwrite our file with the latest code from TFS, and we were able to check in the version we wanted to.
I need a beer...
The edited files are no longer with read-only status.
So this is the solution:
Close the project. (Or use TfsGoOffline, I love this, you can skip 2, 3, 4)
Disconnect internet.
Open the project and it will now in offline mode.
Reconnect to the Internet.
Right-click the solution and select "Online".
VS will checks all files that are not "read-only" and treats them as "changed" and mark as check out.
Now all files that have been replaced are successfully checked out.

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.
