    <p>Error 1   The build stopped unexpectedly because of an internal failure.
    Microsoft.Build.Exceptions.BuildAbortedException: Build was canceled.
    Failed to successfully launch or connect to a child MSBuild.exe
    process. Verify that the MSBuild.exe
    "C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" launches
    successfully, and that it is loading the same microsoft.build.dll that
    the launching process loaded. If the location seems incorrect, try
    specifying the correct location in the BuildParameters object, or with
    the MSBUILD_EXE_PATH environment variable.    at
