Ok.
I start a new asp.net web project.
Add a refernce to the reimers.silverlight.dll
Drag a virtual earth map onto the page and it all works.
If I now in code start to do anything it gives me the error message.
If I browse to and include the system.dll libary I get a load more errors like:
Error 2 'EditorBrowsableAttribute' is ambiguous in the namespace 'System.ComponentModel'. InternalMyTemplate.vb
I'm also adding a silverlight refernce to a new project. Should I add the refernce to a differnent project?
I've got the silverlight 3.0 SDK installed so I assume that I'm using the newest edition of silverlight.
Any Ideas?
