Greetings, I'm getting an Compilation Error. I have a funny feeling its something completely common and easy to take care of. But I'm new to this environment.
Help would be greatly appreciated.

Hi there,

Sounds like you created a Web Application Project rather than a Web Site Project. WAPs don't support the App_Colder (but they allow you to place code files anywhere else).

Take a look at chapter 2, page 37 for instructions on creating the proper project type for this book. Refer to page 34 for an explanation of the differences.

If you want to continue with the book without recreating the site, you can use the site from Chapter 7 (from the code download that comes with this book) as your starting point for this chapter.

Hope this helps,

Imar
