The Windows Live Tools team is currently testing the November 2007 CTP Release with the just announced Microsoft Visual Studio 2008 final release. At this point, we only have one known issue (see below). We will be doing more testing this week and will publish any additional known issues at http://dev.live.com/tools/.  

Known Issue: When using the current Windows Live Tools release with the Visual Studio 2008 final release,  you will need to make changes to the web.config file for any project built using the “ASP.NET Windows Live Web Site” template. Please be sure to update the version of the System.Data.DataSetExtensions assembly in web.config file to 3.5.0.0.
