问题
I have the usual type or namespace name does not exist error, except that I have referenced the assembly, the using statement does not show as incorrect and the classes I am referencing are public. In fact, I reference and using the same assembly in a different solution to do the same thing and it works fine.
This is VS2010 by the way.
Any ideas anyone?

I have discovered the answer to this problem if anyone else is interested.
In my main application I target the .NET Framework 4 Client Profile, but in one of the referenced assemblies I target the full .net framework. Whilst the intellisense and Visual Studio itself don't report a problem, the compiler throws an error. Not an error relating to the target framework mind, just a "The type or namespace does not exist" error relating to my namespace rather than the one that is missing in the client profile version of the framework.
