1. Compile them against Profile7.
   a. Swap out a few APIs (e.g. using GetTypeInfo for reflection).
   b. Introduce an abstraction layer so that we don't have to instantiate
   DkmDataItem (caused a VerificationException).
   c. Include WindowsProxy.winmd as an EmbeddedResource directly, rather
   than through a resx file.
2. Swap the output locations of the ResultProvider projects: Portable goes
to the main output directory and NetFX20 goes to a subdirectory (NetFX20).
3. Include the Portable ResultProvider assemblies in the EE vsix, rather
than the NetFX20 ones.
