I have used Authorize.NET in quite a few ASP.NET MVC Web Applications and really did not care much for the SDK. It always seemed a bit cumbersome and verbose.
I am now working on a new ASP.NET MVC 3 Web Application requiring Authorize.NET and was tickled to death that Rob Conery was working on a simpler SDK that only takes 3 lines of code and uses a Fluent Interface when appropriate.

If you are developing ASP.NET MVC Web Applications and need to implement Authorize.NET for credit card payments, check out Rob's Authorize.NET SDK here.
