Oh my lord above. I have been working towards last week for about 3.5 years altogether. It started with an incubation in the Connected Systems Division (CSD -- the folks that own WF, WCF, BizTalk, etc) doing work to see if modeling was a feasible way to build applications and we just announced the work so far along these lines at the PDC last week. It's called "Oslo" and here are the top places you should look to get up to speed on it:

Microsoft "Oslo" Resources

• "Oslo" Developer Center
• Download the "Oslo" SDK
• Ask a Question About "Oslo"
• Report an Oslo Bug
• A Lap Around "Oslo" (PDC video)
• "Oslo" - The Language (PDC video)
• "Oslo": Customizing and Extending the Visual Design Experience (PDC video)
• Building Textual DSLs with the "Oslo" Modeling Language (PDC video)
• "Oslo": Repository & Models (PDC video)

But don't take my work on "Oslo." Check out what the world is saying (in no particular order -- honest!).

But always remember Lars -- you were on stage the week we announced it. You were there from the beginning!

I put a post developing a simple "to-do" language in Mg. Feel free to link to it:

Justin, that's sweet!
