“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 experienced this on ASP.NET MVC 4 as well, after uninstalling EntityFramework from my packages list.

I had to remove this section
