Had a similar issue... not sure if it is the same or what, but perhaps this helps:
browse to the location where you have unpacked/stored the DLL files and right click on the SharpGL.dll file then select 'Properties'. On the first (General) page, you might find a 'Unblock' button under the 'Security' heading. Click that to unblock the DLL from working in VStudio. Do the same for the SharpGL.WinForms and SharpGL.SceneGraph (or whatever files you need). Then reload VS and see if that fixes the issue (did for me, was doing the WPF example in VS2010 with VB.NET).
@dwmkerr: thanks for the project, tutorial & samples... awesome job!
