Question

What are the advantages of using Asynchronous controllers in my ASP.NET MVC website?
Please explain using simple terms; I am not a .NET expert

Answer 1

I think the documentation says it in pretty simple terms: http://msdn.microsoft.com/en-us/library/ee728598.aspx

The AsyncController class enables you to write asynchronous action
methods. You can use asynchronous action methods for long-running,
non-CPU bound requests. This avoids blocking the Web server from
performing work while the request is being processed.
