I'm trying to migrate an existing ASP.NET WebForms "Web Site" (e.g. deployed as source files, compiled on server on-demand) to a "Web Application" (precompiled, deployed as markup + DLLs).I've been following the steps in this MSDN blog post but after I copy all the ASP.NET pages and controls I am getting dozens of errors like these:In \[code\].designer.cs\[/code\] files:\[quote\] The type 'My_Page_Name' already contains a definition for 'field_name'\[/quote\]In code-behind files:\[quote\] Type 'My_Page_Name' already defines a member called 'event_Handler' with the same parameter types\[/quote\]In markup files:\[quote\] The name 'Property_Name' does not exist in the current context\[/quote\]All the compiler errors are like that (i.e. the references seem to all be OK).I suspect there is some issue with the markup files, the code-behind files, and the new \[code\].designer.cs\[/code\] files that the "Convert to Web Application" command created, but I can't figure it out.
