Created Issue: Is there a version for .Net Framework 3.5? [5722]

I am trying to incorporate Mathnet into a .Net Framework 3.5 scenerio, but I am getting errors from Visual Studeo telling me that the .dll is compiled for .Net Framework 3.5.

Does there already exist a version of the Mathnet .dll that will run under Framework 3.5 or do I need to learn how to compile/build the .dll file?

Thanks
