Fundamentally, it's heavily inspired by Rails. Although it doesn't have an ORM, there are ActiveRecord clones available for .NET anyway. The components that resemble Rails resemble it a lot. ASP.NET MVC was not meant to recreate the entire Rails environment and tool chain. So it does not have things like database migrations, automated deployment scripts, etc. built in. These things are provided by third-parties however.

I wouldn't choose ASP.NET over some other open source framework because of this MVC framework. But it would make ASP.NET development a lot less aggravating if I were forced to do development on ASP.NET.
