TFS Mapping lost local code - tfs

I have a solution on TFS "Project One".
"Project One" was copied via external to another device of mine and i needed to map the solution on the new device to source control. Once i mapped the project, it replaced all the source that was local with whatever was last on TFS for the project. Any way i can get my local source back or is it gone forever?
I had not done any backups on the local code as i didn't think it would delete my current source. In fact i thought it would as me to do a merge.
I had a look at this link after my code had been replaced

Unfortunately you've lost the changes as TFS has overwritten the local files. You set up the workspace after making the changes so TFS didn't know anything about them in order to merge.
If you created any additional files that weren't under source control then they should still exist locally, so maybe you haven't lost everything
In future, if you setup the workspace first then you can obviously make changes to the files and TFS will know about it.
Alternatively, map the workspace to a different local folder and then copy in your changes. If you are using a local workspace then TFS will generate the pending changes for you.

re-map local TFS copy

I am not sure how this can be done. I searched internet to find a solution but did not fine any.
I had a copy mapped to my local folder of a TFS project. But, somehow the mapping is removed (I do not know why), and right now showing "Not Mapped" in Server Control Explorer.
I see that I still have local physical copy. But, I have pending changes in that copy.
Anybody can help how can I re-map to the same local copy folder and then check in my pending changes?
First of all, backup your pending changes to another folder.
Then, click on the "Not Mapped" and map again the local folder with the files.
When VS will ask you if download the files, press "Yes".
Now, VS will say that you have a conflicts (because your previous changes), so resolve the conflicts the choose "Keep Local File Contents".
Now you can check-in the changes to TFS (those changes are your "Pending Changes").

TFS ? - check in is not showing any changes

i initially downloaded code from TFS to a directory and then made a copy of that directory and made changes to the code in the copied directory, but when i copy the copy back to the original download directory, the check in is not showing any changes, so please let me know how i can get the new code back up to TFS?
thanks very much!
If you're using a server workspace, then changes made outside the context of Visual Studio are not tracked -- you will have to check out the files you changed in order for it to pick up changes.
If you're using a local workspace (which are recommended and were introduced in TFS 2012), it should Just Work.
You are probably using a server workspace. You can change a server workspace to a local workspace in your workspace management view.

How to identify files updated outside of TFS

We have a nopCommerce website of a client's that one of their IT guys was modifying views directly on the web server. They now want to do more extensive changes so we want to put the baseline NopCom code in TFS.
Then, ideally, we'd like to be able to identify all the views that were changed directly on the web server and have those changed views be recognize as changes in TFS source control to check-in.
Is there anyway to do this in Visual Studio/TFS in batch? i.e. it would be great to do a check-in locally so all the base code of NopCom was checked in to TFS, then download the website files and overwrite them in the local workspace and have TFS recursively do a diff and determine if any new files were added or existing ones changed and mark those for check-in.... I know...I'm probably dreaming, but any other smart workarounds appreciated as well, assuming this won't work.
TFS does what you want. To set up Team Foundation Version Control (TFVC) on your dev machine, you just need to create a workspace and then add your code. Check link: https://www.visualstudio.com/en-us/docs/tfvc/set-up-team-foundation-version-control-your-dev-machine
When your codebase is under version control, you can develop your app, create and open files in Solution Explorer and write your code, while version control does other work for you. When you check files in and out, it keeps track of your changes and creates a history of your project.
You can use the Diff window to clearly see the difference by comparing folders or files. You can compare server folders and local folders to each other, and view the differences between the contents of each folder. You can compare two server files, two local files, or a server file against a local file and view the differences between the files.
You can get more details about TFVC from website below: https://www.visualstudio.com/en-us/docs/tfvc/overview

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.

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.
