I am pretty sure this has to do with Xamarin.Forms.targets.  Please look at the following project:

And try to build it.  You will see 1 project that builds as expected (WPF), but the other one (Xamarin.Forms PCL) does not.  Seems like the full name of the class is not being used somewhere during the build, causing the error.

Please let me know if you have any questions around this.
