“The name 'HTML' does not exist in the current context” in MVC 3 Views

Question

I´m starting to use \"MVC 3\" but I´m facing some little problems. In my Views, when I code something like this:

@if(Request.IsAuthenticated) {
    

        

Answer 1

I have solved this issue with the old, good, wise Microsoft default solution: reinstall all the things again.

Uninstall and Reinstall the Visual Studio 2010 and MVC 3 Framework.
