I've built web sites using classic ASP, ASP.NET web forms and lately ASP.NET with ExtJS. However, I've always felt that I've had to do a lot of the heavy lifting and that there was no real RAD until the application was fairly mature.
I've only briefly looked at RoR and Django, but they look like a step in the right direction. Does anyone feel they have the equivalent mix of .net technologies for creating web sites quickly?
EDIT: I wanted to stay with mainstream tools (esp. open source or 'low cost') that work with ASP.NET. Also interested in fast framework configuration/setup, as my current project took lots of initial code (my)generation template work to get it to a RAD state.
