John Rusk left a comment on my Developers ditching Microsoft for Rails post and brought to light the fact that developers might not be leaving because of what Rails is doing right, but instead because of what .NET is doing wrong.  I definitely agree that many of the reasons people leave the .NET world for technologies like Rails is because working in .NET isn't as smooth as it should be.  One of the things that makes Rails so successful is its focus, and the embracing of constraints.  Rather then trying to be everything to everybody, Rails is focused on a specific vision.  As I've said in the past, Rails is opinionated software.

For those looking for Rails-ish frameworks in the .NET world you might want to checkout SubSonic and Castle's ActiveRecord and MonoRail projects.  I just had De-ja-vu.
