I just updated VS 2010 from Professional to Ultimate, specifically to gain access to the Architecture Modeling utilities.
After successfully creating a new Modeling Project, I have been unable to create a usable Layer Diagram. Each time the VS designer shows the diagram, VS freezes, requiring a forced close via Task Manager.
I have done a VS 2010 complete repair/reinstall, but continue to have the same issues.
I do have Resharper and Telerink JustCode installed along with some power tools.
If anyone has had similar experiences, I would love to hear how you managed to solve them.
