.Net not equals C#. C# is great, but .Net sucks. limited ecosystem, no one want to implement good open soure project on .net stack. no similar level project like JBoss.

I would say that not having J2EE and JBoss is a plus for .NET or any other platform :-)

There is a whole new set of framrworks for building web applications. My favorite frameworks include:

* ServiceStack: everything you need to build sophisticated web apps with a clean, beautiful API.

* WebAPI: if you want to get a more "Enterprisey" set of APIs

* ASP.NET MVC: .NET's approach to Ruby-on-Rails-esque development.

* SignalR: real-time web applications.
