Unmanaged Exports (DllExport for .NET) and MSBuild error

Question

I've installed Nuget package "Unmanaged Exports (dllExport for .NET). This works fine using MS Visual Studio 2010.

Using MSBuild (Windows SDK v7.1) I get an error Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

Any idea how this can be solved?

Partial MSBuild output:

I've just run into the same problem. The RGiesecke.DllExport.targets file references $(DevEnvDir), which won't be defined in the environment you're running msbuild in (but will be from within Visual Studio). I took the quick and dirty approach of adding a system-wide environment variable on the build server (set to "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\") to work around it, as I was in a hurry.
