Error while running MVC3 Application

i have Visual Studio 2010.

Recently I was using MVC2 and due to some reason I installed MVC3 in my computer. Everything was working fine, till today.

Now when I am creating new project, I am getting below error:

When I clicked on debug

When I went to the folder and tried to open the solution I am getting this

Please help

EDIT 1

When I open the C# project file of the application and t开发者_运维知识库ried to run I am getting the below error

Also when I added a controller and tried to right click on the method to create view. I am not getting any option of "Add View"

I suspect the problem is due to any corrupt DLL or assembly.

Edit

Linked to another question Error while running MVC3 Application after reinstalling also

I would try uninstalling and then reinstalling the MVC3 binaries in Add/Remove Programs. Be sure to grab both the MVC 3 and MVC 3 - Visual Studio 2010 Tools.

Note: I am saying the Tools as well because VS crashed on you when you tried to create a new application.
