OpenCV or Emgu in Unity

I am trying to use Emgu in Unity for a project I am working on. My problem is that when I import the emgu dll’s into my monodevelop project, I get the following error:

Internal compiler error. See the console log for more information. output was:

Unhandled Exception: System.TypeLoadException: Could not load type ‘System.ServiceModel.ServiceBehaviorAttribute’ from assembly ‘Emgu.CV’.

Any help would be greatly appreciated.

PS. The DLL’s are in /Assets/Plugins

OH MY!! The problem was that the build setting were set the .NET 2.0 subset. Why was this so hard to find?!
