The ASP.NET Forum solution is missing the codebehind files. How come?
Above all, the “Codebehind’ attribute is NOT an ASP.NET attribute, it is a Visual Studio attribute. Trial version and full-version with no sources are not supposed to be opened in Visual Studio, they are supposed to be installed on a webserver. Both the trial version and the full version are distributed as a compiled .DLL file which does not need the codebehind files to run. Codebehind files are included with the “source-code” license of the forum software.
