Edited Issue: RazorGenerator.MsBuild throws when trying to build [20]

I installed the RazorGenerator.MsBuild package but got an error after adding the line above to my project file:

packages\RazorGenerator.MsBuild.1.0\tools\RazorGenerator.targets(16,9): error : The parameter 'PhysicalDirectory' is invalid.packages\RazorGenerator.MsBuild.1.0\tools\RazorGenerator.targets(16,9): error : Parameter name: PhysicalDirectory

Any suggestions?
