Error: “The file '/MasterPages/MainMaster.master' does not exist.” (Yes, this file does exist!)

Question

I just got a new desktop computer with Windows 7 Pro as the operating system. I installed Visual Studio 2008 on to this new computer and tried to open a previously existing ASP.

Answer 1

the error comes on the web form like this

<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site1.Master" CodeBehind="add_drivers.aspx.vb" Inherits="au_transport.WebForm1" %>

correction

<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="Site1.Master" CodeBehind="add_drivers.aspx.vb" Inherits="au_transport.WebForm1" %>
