APS.NET MVC3 Development
I work like ASP .NET developer for 10 years and I really enjoy and happy with that especially to use MVC3 extension. It gives freedom and helps to reach the goal with best quality. Supporting MVC3 solution is pretty easy as well.
I used to ASP .NET classic approach for 5 years and must admit that MVC3 way it much much better and gives a possibilty to react quickly on bussines needs.
Mvc3 Razor engine is amazing thing ! I recomend to use it instead of ASP .NET classic approach.
