I am trying to follow a SharpMap tutorial from the official sharpmap documentation here:
<http://sharpmap.codeplex.com/wikipage?title=Create%20a%20map&referringTitle=How%20to>...

My problem is that Visual Studio underlines the Geometry part of the SharpMap instance as an error. Its says "the type or namespace 'Geometry' does not exist in the namespace 'SharpMap' (are you missing an assembly reference?)"

What can I do to resolve this error? (Please note: I have added all the references available for SharpMap).
