Remarks
Use this collection to store the mapping from the type of a service to the object that provides it in a way that is aware of embedded types. The comparer for this collection performs a comparison of the GUID properties of the Type key instead of doing a reference comparison, which will fail in type-embedding scenarios.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
