How to implement custom diagram Project for VS2010?
Where can I find the exmaple?
It is no diagram designer project (Class Diagram Project/Sequence diagram project) example in the Visual Studio Integration Samples.
I hope can implement custom diagram elements in VS.NET Toolbok window,and custom diagram designer (like edmx diagram designer and sequence diagram designer).
Look at the Visual Studio SDK Integration Samples. Specifically do any of the Editor or SDM samples give you information in the area in which you are looking.
