It has been a lot of work, but I have almost all of the NORMA bits working on VS2010 now. VS2010 has some significant platform changes (code generators (generated code cannot be shared as with VS2005/VS2008), package registration (build, setup, extension registration), editor back end (fact editor), property descriptor handling (properties window), toolbox population (self-explanatory), mouse actions (toolbox interactions and constraint editing), and many more small things).
The three parts I haven't done are code generation (Microsoft deprecated most of Microsoft.Build.Engine, and it will take me at least a day to rewrite the ORMCustomTool project file interactions), Database import (should be straightforward), and Setup (aforementioned changes to package registration will modify data). At this point, I'll be modeling flat out for at least a week using the platform, so I should be able to iron out any remaining issues, then finish up these work items. I should get a release out in a couple of weeks once I'm comfortable with the modifications.
Thanks for being patient, I know not having this is hindering NORMA use for a lot of you. The current change set has 317 files in the core repository with several more to go, so please be patient for a bit longer while I get some product-use time in and make sure things are stable and consistent.
