I have a solution that has one class library project, and the others are WPF applications. I have added class library's reference the but, but both of them cannot use its classes.

So, what is the problem?

NOTE: sorry for tags, it's safari's problem.

Make sure that all your projects target same Framework. It may be a case that your library class project targets full .Net Framework 4.0 while your wpf projects target .Net Framework 4.0 Client Profile.

To do that go to project properties of each project in a solution and check Application | Target Framework property. Alternatively you can download VSCommands 2010 extension and see all properties in one place via Solution Properties window.
