Type 'Class' is not defined in Web App upgraded from VS2003 to 2010
Hi, I have a Visual Studio 2003 ASP.Net Web app that I have just upgraded to a Web Site in Visual Studio 2010. In the project I have a vb class module which is inherited by various aspx pages (in the aspx.vb file). Since upgrading the aspx.vb files can no longer see the class module.
Has something changed in the way that inheritance is handled in 2010?
