What are some alternatives to ReSharper?

CodeRush, by DevExpress. (Considered the main alternative) Either this or ReSharper is the way to go. You cannot go wrong with either. Both have their fans, both are powerful, both have talented teams constantly improving them. We have all benefited from the competition between these two. I won’t repeat the many good discussions/comparisons about them that can be found on Stack Overflow and elsewhere. 1

ASP.net Web Forms, get aspx/view errors at compile time?

I know this can be done with mvc2, but is there any way for visual studio(2010)/resharper(6) to check for errors on aspx pages at compile time and halt the build? Resharper can detect the errors just fine, so it seems like there should be a way to integrate a check of all the aspx pages in to the build process.
