When does a Portable Class Library reference mscorlib, Version 5.0.5.0?

Question

I have been trying to figure out the combination of platforms which when selected, causes a Portable Class Library to reference mscorlib, Version 5.0.5.0.

I tried many combinations including Silverlight 5.0, but my PCL always referenced 2.0.5.0

Further, there is no mscorlib, Version 5.0.5.0 in any my Reference Assemblies....\ProfileXYZ folders.

Answer 1

There should be no combination of platforms that would get you a Portable Class Library with a reference to mscorlib version 5.0.5.0. I think that reference would mean the library was compiled for Silverlight 5.
