Force all project contents in a registry to use the same version of .NET assemblies based on the target framework of the project - a .NET 2.0 project referencing .NET 1.1 projects will see .NET 2.0 completion for objects returned by the .NET 1.1 assembly.

Fixed bug that caused assemblies referenced by CF projects to always reference .NET 2.0 projects, causing code-completion to fail when the .NET 2.0 registry was not initialized
