master pages in vs2010

I have been trying to migrate a VB.net web site to a web app called "VMA".  One of the most maddening problems is with master pages.

In the root folder I have created a master page called "Master".  It creates the page OK with inherits="VMA.Master" (note the app name at the beginning), but no namespace in the designer or the code-behind.

Next, I add a new web form, "Default", to use this new master page.  When I run the app, it keeps throwing the error "could not load type "VMA.Master".  

Please help.  This is making me nuts!

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There is usually a problem when going from a Web Site model to a Web Application model, because of the attributes that are used.  I believe that the Web Site model uses the CodeFile attribute, and the Web Application model uses the CodeBehind attribute.
