I am following in the book and I discovered that when I change the CSS the changes are not reflected in the web pages. They did reflect the changes for a while but then, all of a sudden, it stopped. I posted this problem in the MS forum and someone advised me to do a full rebuild when I am ready to run it and delete the relevant files in the Temporary ASP.NET folder and that worked FOR ONE TIME. Then it went back to not updating at all. I made some changes to the 'Plain Yellow' CSS in Marco's project, did a full rebuild, and they too do not update the web pages. I feel like I am missing something simple here but I can't figure out what it is. Thanks for any ideas.

I found that doing a page reload reflects CSS changes.

Thanks Mythical. I'm new to ASP and that never occurred to me. I thought I had a bad VS install.

Sometimes reloading the page doesn't work for me. I find a more reliable method is to empty the browser cache, then the CSS changes are reflected when you reload.

In your IE browser:
Tools->Internet Options->Temporary Internet Files->Delete Files
