Please help me out for above error. i already spend 2 days on it.

Answer 1

You can only edit the BuildProcessTemplate from the version of Visual Studio that matches the TFS version. So even when you do development from Visual Studio 2012, you need to edit the BuildPorcessTemplate.xaml from Visual Studio 2010.

Since VS2012 uses the 2012 client object model binaries, it generates xaml that is not compatible with TFS2010. Due to all the binding redirects in the devenv.exe.config it is not possible to force Visual Studio 2012 to load the 2010 binaries.

As such you must use VS2010 to edit the 2010 build process templates. You can install VS2010 and VS2012 side by side if needed.

Alterantively, edit the files by hand, they're just XML.
