Cannot use TFService from VS 2012: HTTP code 400 Bad Request


  • Hi all!

    I signed up for TFService and created a project, then I connected to TFService using VS 2012 and created some empty folders and empty branch for the project. Everything was good. The next day I wasn't able to use Source Control Explorer or Pending Changes and I couldn't check anything in. VS 2012 connects to TFService but then gives me this when I try to use Source Control Explorer:

  • Hi Vladislav,

    Thank you for your post.

    Can you use other TFService features in VS?

    Can you log on your TFService site via IE browser?

  • Hi Lily,

    I can establish a connection to TFService in VS, but it gives me three error messages (HTTP code 400) in a row when I open a Team Explorer. It doesn't allow me to check files in or shelve them showing the same error. Web Access only seems to be working fine.

    I can log on to my TFService site via IE and Firefox without any problem.

  • I've resolved the issue by creating a new workspace and removing the old one.

  • Hi William,

    Did you try to create a new workspace? (go to Source Control Explorer and choose "Workspaces..." from the Workspace list on the tool bar)
