I'm using both Resharper and Amethyst (ActionScript plugin). Unfortunately I have to suspend Resharper to be able to work with the Amethyst plugin. If I don't, Visual Studio will crash when creating new Amethyst projects and crashes when closing Visual Studio. And of course code assist isn't working as expected. In short, they do not play nice together. I don't think there is an easy solution, other than suspending Resharper, but who knows!
