Making 'Unrecognized tag prefix or device filter 'asp' Go Away!

I just figured I'd post this since I've encountered it a few times and found it rather annoying.

Once you start working with a masterpages/content forms, at some point, you'll probably get a number of errors saying that your web control elements are unrecognized. (ie, 'Unrecognized tag prefix or device filter 'asp').

The way to get around this is to explicitly specify the MasterPageFile on each of your content forms. Using the is valid, but you will still get the errors in your 'error list', although your app will compile and run just fine.

Specifying the MasterPageFile explicitly on each content form will remove the errors.
