How to create a class diagram for the whole solution? There are several projects in the solution, and I want to create a class diagram from all of them.
I am using Visual Studio 2010 Professional.
You can create a class diagram only for the project, and not for the entire solution. You can use the sequence diagram and class diagram to control how everything is connected.
Not sure what you mean by class diagram, but you can check out Doxygen . It supports C #. It is easy to use and works well.
