The project type is not supported by this installation

When I try open MVC project developed from MVC3 Frame work From Visual studio 2010 with Mvc 4 Frame work, I will got error " The project type is not supported by this installation"

In This post I will explain How to solve this problem.

First up all we will saw why this error is occur

        When we install VS 2010 in our machine MVC 2 is default install in our system. So By default We can only develop MVC2 project using VS 2010.
The Microsoft Asp.Net folder looks like bellow

For my developing purpose I install MNC4 in my machine so the Microsoft Asp.Net folder looks like bellow

Then I will down Load sample MVC 3 project from Internet and try to open the project in VS 2010,In that time I will got the following error “The project type is not supported by this installation” because I did not install Mvc 3 in My machine. So try to install MVC3 in my machine after that I try to open the Mvc 4 project in VS 2010.It will open the project without saying any error.
