Ok, so MVC 3 just RTM’d, so we are going to take a step back and upgrade.  First off, go uninstall the RC – be sure to uninstall both mvc 3 and the vs tools.  Once that is done you can open Web PI and install mvc 3.  If you don’t have Web PI yet, you can get 3.0 from here. http://www.microsoft.com/web/downloads/platform.aspx 

In reading the release notes, which you can download here, seems we shouldn’t have any issues moving this project forward since we are so new into it. The install takes quite a while because it does some updates to Visual Studio as well.
