TFS API: GetLocalWorkspaceInfo always returns null

Question

On one of my machines, I get a return value of null from any GetLocalWorkspaceInfo call. I have isolated to problem to where it even fails for this simple progr

Answer 1

In my case, this issue occurred because of VersionControl.config file put under TFS cache (C:\Users\DeepakR\AppData\Local\Microsoft\Team Foundation\5.0\Cache\Volatile\0cb76a25-2556-4bd6-adaa-5e755ac07355_http)folder goes for a toss i.e. the configured workspace information weren't available as expected.

So, It basically needs a refresh of VersionControl.config file. Auto Refersh happens when Visual Studio gets loaded again i.e. it pulls the configured workspace information from Server and updates the config file or even if we execute tf command utility (tf.exe workspaces /collection:TFSURL)

Microsoft.TeamFoundation.VersionControl.Client's(v12.0.0.0) Workstation class has a function EnsureUpdateWorkspaceInfoCache which will do the same trick

VersionControlServer vcs = (VersionControlServer)tpc.GetService(typeof(VersionControlServer)); Workstation.Current.EnsureUpdateWorkspaceInfoCache(vcs, Environment.UserName);

Hope the suggestion helps to resolve the issue.

This is how to find workspace when you have server path:

  Workspace[] workspaces = _versionControl.QueryWorkspaces(null, Environment.UserName, Environment.MachineName);
  return workspaces.FirstOrDefault(w => !string.IsNullOrEmpty(w.TryGetLocalItemForServerItem(ConstDefaultFlowsTfsPath)));

Where ConstDefaultFlowsTfsPath is server path with "$" for instance : "$/MyCompany/Services/DiagnosticsFlows"

You could also replace the last line to:

return workspaces.FirstOrDefault(w => !string.IsNullOrEmpty(w.GetServerItemForLocalItem(myLocalPath)));

and that should work for you too.
