TFS BUILD : The tools version "12.0" is unrecognized. Available tools versions are "2.0", "3.5", "4.0"..

Hi All

During the TFS Build you can face the error “The tools version "12.0" is unrecognized. Available tools versions are "2.0", "3.5", "4.0"

This error is triggered during the command SysTreeNodeVSProject::importProject(@filename) and so it’s related the C Sharp Projects.

In order to fix, there are two options:

1-      Install Visual Studio 2013

2-      Install MicrosoftBuild Tools 2013

All the best!
