Ok, I figured it out. This appears to be a stricter enforcement of XHTML. After looking more closely at the ASP page, it appears that though it didn?t catch it origanlly in the VS2005 Beta 2, it did catch it in the VS2005 RC.
One example in my master page was this.
<table border="0" cellpadding="0" cellspacing="0" width="600" align=center>
In the current version, it shows ?align=center? as being something that should be done in CSS. Instead of in the table tag it self. After correcting all of the items that should have been done in CSS. Problem is now fixed.
Thank you
