Run Time Error after converting dll from VS2008 project to VS2010

I have an application that has a GUI project written in VS2008 that interfaces to several dlls also originally created in VS2008 C#. I recently upgraded my VS to 2010. When I imported the dll projects to VS2010 everything seemed to go smoothly and they compiled properly with a targeted Framework of 3.5. However, when I try to run the GUI, which is still compiled under VS2008, I get runtime errors when the GUI tries to instantiate the class defined in the dlls. Do I have to convert the GUI to a VS2010 project as well? What am I missing here?

Thanks for any help.

Catch exception and dump exception information, show the code when exception was thrown.

You might try deleting and then re-adding the DLL references to your GUI project.

I am having large issues with this too and readding the DLL references seems the best way.

That did the trick. Thank you very much!
