Parser Error Message: The file '/theMaster.Master' does not exist.

Working with master pages for the first time. I keep receiving a parser error when I try to load a page that utilizes my master page called theMaster.Master. I thought it was something I mucked up somewhere else in my code so I started again from scratch, left all the automatically generated code alone and I'm still receiving the error.

Below is the entire error I'm receiving. What's the solution?

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

It is advisable to use "~". The problem is probably not related to .NET Framework version differences. It is most likely related to the IIS configuration of the site, particularly the applications root directly.

1. Make sure that you have marked the site as an application in your IIS Manager.
2. Make sure that you configure the application root directory to the correct path, for example, if the site is in c:\inetpub\wwwroot\MySite, the Website should point to that exact folder in the IIS Manager.
- If you DO NOT create a virtual directory for the application in IIS, you will stil be able to browse the site as http://localhost/MySite... BUT in this case, the application root directory (represented by ~) is actaully the c:\inetpub\wwwroot folder.
- What you want is to be able to browse http://localhost/MySite but for that to actaully be the application root. So you need to create a new application/virtual folder in IIS that points to c:\inetpub\wwwroot\MySite, then ~ will resolve correctly.

However, if you want your application to just be accessed without a virtual folder i.e. http://localhost/ on the production server to just fire up your applicaiton without requiring the "MySite" to be specified like so http://localhost/MySite, then you need to change teh Home Directory of your Website in IIS. So if you are using Default Web Site, you need ot change default website to point to c:\inetpub\wwwroot\MySite instead of c:\inetpub\wwwroot\.

Hope this clarifies things for you and hope it resolves your problem.

What does your master page directive look like? It should look like this:
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="theMaster.master.cs" Inherits="Logan.theMaster" %>

Try replacing the tilde (~/theMaster.Master) with a period (./theMaster.Master).
Check that all code behind names match the names in the Page directives exactly.
Is this happening inside your development environment or after deployment or both?

tried changing the ~ to . - no change. It does work in Visual Studio. I started a new project, kept it very simple and it again works in the development environment but won't work live. I've attached the Master file and default web form using the master page.
Tom BeckCommented:
I copied and pasted your markup to a new master page project in VS 2005. It worked in VS and it worked when I deployed it to a web server.

Could there be a mismatch of the IIS version or .NET framework version between your development environment and the web server?
