ASP.NETName main page structure: value cannot be a null error

I am looking at some ASP.NET tutorials, and the first one I'm looking at is creating a homepage. When I create the main page, I get an error message:

Value cannot be null.  Parameter name: frameworkName

This happens on the first line of my main page (MasterPage.master), and it is created by default, which is created - I did not change it at all:

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>

Can someone tell me what is the parameter frameworkNameand how can I get rid of this error? FYI: I am using Visual Studio 2010.
