The type or namespace name 'WCFService' could not be found in WSP

Question

Hi

I have a solution that contains a Web Site Project and several class libraries. The WSP is a DotNetNuke instance (which is why I'm not using a Web Site Application). I'm having trouble referencing one of my class libraries from the WSP.

The error I receive is:

error CS0246: The type or namespace name 'WCFService' could not be found (are you missing a using directive or an assembly reference?)

This error is raised in one of my WSP codebehind files, like this:

using WCFService;

However, I have added a reference to the WCFService project to the WSP. I've even tried copying the DLL manually to the WSP bin folder. Intellisence is working for references to this class library in my code, so I can't understand what the problem is.

Anyone have any ideas?

Thanks in advance!

Mark
