vs2010 express multi-project solution organization

[murrayja]

I have built two projects, each represents a web page. When I treat them singly they both work. When I put them in a multi-project solution the solution builds but doesn't run. I get an error that reads "cannot find type xxx' where xxx is the class name of a projects default.aspx file. I suspect that I will have to merge the dlls and web.configs but I am not sure. My questions are ...
1) is there a solution in the project properties?
2) if not, what and where do I merge dlls and web.configs.

thanks
