Hi,
Just to add that it's been the "Standard or above" editions of Visual studio that have been (and I'm guessing still are) required. From the team, I recall that the fact that the Express Edition did not allow for the DSL custom tools required by nORMa at this time.
You may have also seen that the team plans to support VS 2008 (due out in Feb 2008 - but available in pre-release as free DL from MS now). I heard from MS rep that express versions of VS 2008 will be available - but forgot to ask if these will have the same limitations on custom tools. In any case, I've also heard from nORMa team in earlier posts, that moving away from VS requirements is something they plan to do - but when, I couldn't say.
Finally, if you are testing the nORMa tool with VS, it has been a requirement that you use a Windows, or Console "project type" to build the ORM model - Data, Website, etc..., types haven't worked. The project type just lays down the bones in VS, and you can forget about the Windows form as soon as it's created.
BRN..
