"are you missing a using directive or an assembly reference?" but the namespace and reference are correct

Question

I've got the following error when builing my project.

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

But I have put a using in my code and a reference to the dll. It is a WPF application that exists of 3 projects.

I checked the references, even intellisense works when I put the using directive in the page.

thanks,

Filip

Answer 1

using '.net 4.0 Framework' instead of '.net 4.0 framework client profile' is the solution.
