>Hello. I upgraded to MM 4 and VS 2010. I'm following the help file on "creating entity framework business object". I added my tables to the edm and built the project. The build was successful. I then created my classes with the BLG and now I get an error in my edm for each of my classes "'ClassName' must not specify different base classes".

Hi Robert,

Not sure about your specific situation but I remember having a similar issue. When I had an issue, there was some naming issues or something in the EDM but I was able to find them and correct them. If I get a chance later, I will run through this again and see if I can find what that was. Let me know if you don't find it.
