Sharris solution worked for me.  No version of ASP.NET was selected in the properties tab on the virtual directory for the website on the server.  I am very thankful for these forums and need to contribute.  This would take 4096 years w/o these forums!

Its very easy to fix this problem.

Go into your web site properties and see what version of ASP.NET you are using. If its 1.1, you need to change the <%@ Page %>

directive to use Codebehind="...". If its ASP.NET 2.0 or later, you need to use Codefile="..." and remove the Inherits="" phrase. Thats it! Most people are switching framework versions on different servers and are not make this change at the top of their ASPX pages. - www.stormdetector.com
