ASP.NET MVC 3 in production?

Question

Now that ASP.NET MVC 3 is in beta, and ready for "go-live". Would it be safe to use in project, although not prevented I am curious on security, performance and ease of upgrade to release version.

Answer 1

I started using it in a project, but I couldn't get Dependency Injection working (using Unity). I was liking Razor, but the lack of intellisense did hurt my productivity.

I am sticking with MVC 2 for now. When this is more documentation on Razor available, I will probably upgrade to 3.

EDIT: Check out this article. If you don't care about DI, then you might be all set. The only other change was the validation model.
