I am building a new project, basing my code on the design in "ASP .NET Problem Design Solution" but I'm having a problem compiling two of the modules.

At the command prompt, I am getting the compiler error "Class name 'SiteIdentity' is ambiguous in namespace 'BenChEnterprises.WebModules.Accounts.Business'". I also have the same error for the class "SitePrincipal" in that namespace.

I'm getting a similar problem in the Accounts.Configuration namespace, with the class "ModuleSettings".

I am certain that those classes are only declared once in those namespaces. Are there any other reasons they could be "ambiguous"? Is there anything those classes have in common that could be causing my problems?

Many thanks

Found the problem.
For anybody who might have done something similar, there was no error with my source code. The problem I caused myself was when compiling, in the list of assemblies, I specified the assembly that I was trying to compile at the time, so it was referencing itself against itself!
