Unfortunately, as of today (2/28/08), the ReSharper 4.0 EAP still can't handle LINQ (or partial methods, apparently). However, I just can't give up ReSharper's refactoring capabilities and other goodness, so here's how you can disable the code analysis and IntelliSense in the ReSharper -> Tools menu dialog:
If you don't use LINQ (or partial methods), just ignore this advice - use ReSharper to the hilt!
If you're not yet using ReSharper for VS 2008, I'd still advise that you download the latest nightly build and give it a try. You'll not want to go back.
