Edited Issue: DynamicTypeService stops working when EF.dll is loaded into VS [810]

When other Visual Studio extensions load EntityFramework.dll into the main VS AppDomain, the DynamicTypeService stops working correctly. This usually results in the Entity Framework Power Tools showing the message "A constructible type deriving from DbContext could not be found in the selected file."

So far, this has been come up because of the Visual Studio 11 Developer Preview version of the Unit Testing tools, and version 11.2.4.1 of the VSCommands extension.
