ASP.NET 4.0 MVC2 routing on IIS 6

ASP.NET 4.0开发者_开发知识库 MVC2 routing on IIS 6 is not working for me with all the methods used for 3.5 Works fine as long as I build in 3.5 but building in 4.0 and setting the server to use 4.0 I loose my routing. Anyone seen this and been able to resolve it?

Have you checked to make sure that ASP.NET 4.0 is allowed in the web service extensions after upgrading to .NET 4.0 on the server?

See this question.
