    The bin folder contains the compiled code for your application, the files it contains are generated when yuo compile the application. Typically the App_Code folder contains source files and as these get compiled into the various files in the bin folder they are not needed at runtime.

    Under webforms the aspx files contain references to code in the related aspx.vb file, the aspx.vb file is also compiled into the dlls in the bin folder, making changes to the .aspx files without rebuilding and redeploying will result in the compiled files and the .aspx files getting out of sync and the error you are getting is a fairly typical result.

    When you publish your application there should be an option (can't remember where at the moment) that mentions making the website updateable after deployment - might be worth trying that option and republishing.
