The Dynamic Programmer - Extending ASP.NET MVC

I had two main requirements: Composed views and dynamic layouts. This means that the same action can use two (or more) completely different layouts, and the content of the different areas on any of those layouts can change from site to site as well. Besides that, I want my views to be pure html. That means writing my own engine. The good thing is that the framework allows you to plug any view engine that implements IViewEngine.
