I am getting this error on my CI server:
error MSB4019: The imported project \"C:\\Program Files (x86)\\MSBuild\\Microsoft\\VisualStudio\\WCF\\Microsoft.V
I've had the same error - my issue was that MS has modified the way MSBuild looks for the versions of VS in the build process template.
Make sure to use the right build process template. If using TFS2013 and VS2013 use TfvcTemplate.12.xaml
