VisualStudio.NET? yeah?
Yeah. C# + .NET + ASP
I don't know tough to say, I work with VS fair amount. Maybe VS.NET doesn't neccesarily have the ORM strength yet (soon to come if not already in ObjectSpaces which is gorgeous), but I use DTM for this and it works incredibly well.
A .NET app in development feels more like a standard application, and has this same focus on removing page states and automatically binding databases as it looks for Ruby on Rails in the demo. I guess the fully integrated IDE is what takes the cake for me, I get tired of figuring out what scripts do what, especially when I don't work on the same technologies or projects for more than a month at a time.
Plus a library like .NET is full, extensive, simplistic. MS moves it forward, sometimes standards move backwards
