I'm playing around with .NET portable to create a library and have been encountering some issues when trying to create instances of KeyedByTypeCollection.
I've checked my references (.NET Portable Subset) and System.Collections.Generic seems to be showing the KeyedByTypeCollection.
http://msdn.microsoft.com/en-us/library/ms404549.aspx - MSDN seems to indicate that it should be supported as well.
Despite that, Visual Studio & the compiler still seem unable to resolve the type.
Any idea what I might be missing here? Thanks!
