asp.net - "The name 'HTML' does not exist in the current context" in MVC 3 Views

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) {
    <text>Welcome <b>@Context.User.Identity.Name</b>!
    [ @Html.ActionLink("Log Off", "LogOff", "Account") ]</text>
}
else {
    @:[ @Html.ActionLink("Log On", "LogOn", "Account") ]
}

The objects like @Request and @Html is indicating an error: The name 'HTML' does not exist in the current context.

The same occurs with @Context, @ViewBag, @Layout, @Url and others.

See:

But the code is correctly compiled with no errors. The problem is that I cannot use the Intellisense with theses objects in the Views. Is it normal? (I don′t think so). What could be happening?

I have reinstalled the MVC 3 framework but the same still occurs.

Note: this is a new project from scratch, not a MVC 2 migration. This occurs both with Razor engine and ASPX.

This is the Web.Config in the Views folder:

<?xml version="1.0"?>

<configuration>
  <configSections>
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

You could try:

  1. Close the View with the false errors.

  2. Close Visual Studio

  3. Reopen the same project

  4. Open a different View then the one causing the errors

  5. Close that View, hopefully you didn't see any of the similar errors in this View

  6. Reopen the View that gave you problems earlier
