Master page inherits tag question

Question

Going through the microsoft authentication tutorial listed here they have you create a master page. Upon generation by Visual Studio the first list in the file looks like this:

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="FormsAuthentication.Site" %>

The project is called FormAuthentication and the master page is named Site.Master. When running the project I get the error:

Compiler Error Message: CS0426: The type name 'Site' does not exist in the type 'System.Web.Security.FormsAuthentication'

and the line referenced looks like this, in an auto-generated file

Line 133:        [TemplateContainer(typeof(FormsAuthentication.Site))]

Removing the "Inherits='FormsAuthentication.Site' " portion of that initial tag resolves the issue but I'm trying to understand what is happening here. What is actually going on here?

Answer 1

Name of your project (and maybe namespaces) conflicts with ASP.NET form authentification class name: System.Web.Security.FormsAuthentication. I think you are missing namespace name or reference.

Answer 2

If you could rename, or add another level of namespace around FormsAUthentication so that it would be like: Custom.FormsAuthentication.Site, that would alleviate the problem.
