I wish ASP.NET MVC and NHaml existed a year ago when I started my last ASP.NET project. I am in love with the simplicity and elegance. At first, I was worried about losing some of the power of Web Forms. I was way off.
I created my first MVC + NHaml application (CRUD for one model) in a few hours. The same can’t be said for the learning curve of Web Forms. And it is 100% unit tested.
I see much blogging in my future regarding these too libraries.
