VS Express should've automatically opened the default.aspx page. Go ahead and delete everything but line 1. We're going to do all of our page building inside the codefile. Within line 1, add Debug="true" somewhere in the line. This will turn on code debugging so you can read your error messages more easily. If you were to ever put this page on the internet in front of a live audience, you'd remove the debug option.
Empty the Index
With that cleared out, go ahead and open up the codefile. You may as well close the default.aspx page, we won't be going back to it. Continue to the next page to start actually programming.
