I am using Resharper 5.0 beta with Visual Studio 2010 beta 2 with many problems. Most features are working well. I have an ASP.NET MVC 2 project. In Global.asax.cs Resharper is having problems with the "routes" variable, especially routes.MapRoute(). It says that it can't resolve MapRoute() and cannot convert from System.Web.Routing.RouteCollection 220.127.116.11 to 18.104.22.168. This code compiles and runs fine.
