I'm sorry Amit but that doesn't help, as we already understand that you have one class library holding the EF model and another class library holding the DevForce model, and that referencing both assemblies causes the error.   We are unable to reproduce the behavior you're seeing, in other words, it's working for us.  Since we can't repro, we have to assume that something else is going on.  If you'd like, you can send us a sample solution showing the problem.

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.


Thanks,
Amit

We're not able to reproduce the problem if the models are in separate assemblies.  Can you provide some more information on the solution structure?

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.
 
Thoughts?

Thanks for the additional information.  This is probably an issue with probing by MEF (Managed Extensibility Framework).  We're taking a look at it now.

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.

We have confirmed this as a bug.  Thanks for pointing this out.

Until this gets fixed, you will need to keep the raw Enity Framework EDMX in a different project from the DevForce-enhanced EDMX.  Probably not a bad idea anyway if they're two different models.

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.
 
Thanks,
Amit
