Does ASP.net MVC 3.0 RTM play nice with the ASYNC CTP?

ASP.net MVC 3.0 RC1 clashed with the ASYNC CTP in visual studio 2010. Does anyone know if the newly released MVC 3.0 RTM will happily co-exist?

No. The changes that MVC 3 makes to VS and the changes that the Async CTP makes to VS are incompatible.

However, there is an upcoming SP1 for Visual Studio. When that's released, the Async CTP will be refreshed to work with it. (MVC 3 RTM was already designed to be compatible with SP1 when it's released, so they'll happily coexist at that time.)
