Close all open files in Visual Studio and then choose Build Í Rebuild Web Site from the main
menu. Doing so forces Visual Studio to recompile the entire site even if it already had compiled
some parts of it. Visual Studio lists any problems your site may have in the Error List. To verify
that your site is error free, open the Error List (choose View Í Error List from the main menu) and
make sure you don’t have any compilation errors. Fix any errors you may have in your site.
