Do I need to create a application pool which supports .net framework 4.0?
1 Answer
This will depend on the framework version your MVC application is targeting. So if you application is targeting .NET 4.0 the application pool must be set to use CLR 4.0. If your application is targeting .NET 3.5 the application pool must be set to use CLR 2.0. Here's an article covering the various deployment scenarios.
