Most popular architecture used with dotnet

Question

What are the most popular architecture with dotnet? Right now i am using ASP.NET MVC, but i want to increase my work area with more architecture.Please provide me detail and links.

Answer 1

Onion architecture.
Sharp architecture. (it's a framework actually)

Lately - there's buzz about CQRS.

I would like to add Domain Driven Design but it's not an architecture either (despite that it seriously influences it). Because it's popularity increases.

Answer 2

Depends of your needs, you need to discover your requisites and later design the architecture. Look at: Do you have any good examples of "architecture for architecture's sake"?

I suppose SOA or n-tier (witout the UI) are the most popular for back-end. And for clients: asp.net (with mvp pattern), silverlight (with mvvm pattern) or heavy client with any pseudoMVC.
