I have TFS Server 2012 SP1. Eclipse 3.6.2 (Helios Service Release 2). TEE 11.0.0.201211191425
I see a complete team menu, I can check-out and check-in files manually. However if I just start editing a file it will not be checked out automatically :( as it did with 2010 before updates.
I have tried to change settings to "Display progress while checking out" and "Prompt before checking out" - no effect.
"Detect changes..." functionality does not work either.
Only if I close the project and then open it again, the modified file will be checked out automatically (only once).
wtf???
UPDATE: The modified file will be checked out automatically also if I manually check-out/check-in another file in the same project.
Not sure about your specific TFS or Visual Studio version, however in VS2010 you have:
File > Source Control > Change Source Control
If your Solution/Project is listed like above with no Server Name, Binding etc., select it and click Bind. That may get things going again
Problem found
If Visual Studio 2012 is opened on the same PC and connected to the same TFS server, the TEE behaves as described above :(
@Edward Thomson, I think it is a bug. TEE should at least have displayed an error messages.
