Could not load type ‘namespace.pagename’ error when using VB.Net

When I tell my project to run, i get a list of errors- one for almost each page “Could not load type ‘namespace.pagename’ ” After doing some research, I know it’s got something to do with the assemblies loading, and I have double checked that all the properties
in the <%@ Page.... match the location and the name of the code behind files but the knowledgebase article that covers this, only provides a resolution for this error when you are coding in C+.... I've compared the error pages to the ones that do not have an error, and the <% @ Page... declarations all look the same to me. Does anyone else know what it might be?
