Entityframwork with Devforce object model

We have a project that has reference to both Devforce object model and Entity Framework object model, but when we run the project, devforce object model throws exception type "ReflectionTypeLoadException". If we remove the Entity Framework object model reference from the project, it works fine. We have verified the edmx file names and the both are named different. Does anyone know if there is an additional setting needs to be set or missing? We have setup this project setup just exactly as the sample project except it has Entity Framework reference.

Both of these models were created in separate library project and then added as reference, but problem still persist. If I remove the entity framework project reference, then as expected dev force object model works.

Thanks for verifying what we are seeing.  Any estimate of when this could be addressed?   This is a brick wall for us and preventing us from moving forward.

The structure is pretty simple. We are not doing anything out of the ordinary. Entity Framework assembly project was created with .net 3.5 and we had used this for creating dev force object model with previous version. Once it was converted over to 4.0, we created separate assembly project for dev force object model. But if we reference both of these assemblies project, dev force object model ends of throwing "ReflectionTypeLoadException".  Hopefully this helps.
