WCF RIA Serices referencing another RIA Service class library

I am getting an "ambiguous namespace" exception. It is because I have mutiple RIA Services class libr开发者_Python百科aries that reference other RIA Services class libraries. Is it possible to only allow the code generated part of a RIA Services class library and not as a reference?

I don't want to create a monolithic RIA Services class library as our enterprise application has modules that only use certain pieces. Please advise.

It appears that my bin and obj folders were corrupt. I Cleaned the solution and it started working again. I did have to use the "Global" key word to get the application finally working. I am not sure why I had to do it that way since I had a reference to the assembly but it now works.
