There are not many changes, and the biggest one is the installation procedure:
- there is a dependency requirement on .NET 3.5 SP1 (that means you have to have .NET 3.5 SP1 in order for the ASP.NET MVC RC2 to work)
- there is a “server-only” install mode
That’s a big change in the installation tools and, since it’s a new process, it’s the thing that is most likely to break. So, if you want to see ASP.NET MVC RTM-ed as soon as possible, download the latest bits, install the RC2 in as many machine as possible and report any problem you encounter on Codeplex. That will spot problems in the installation procedure.
Source code and futures assembly are available on CodePlex as well.
