现在 ASP.NET MVC 3 处于测试阶段，并准备好“上线”。尽管没有被阻止，但在项目中使用是否安全，我对安全性、性能和升级到发布版本的便捷性感到好奇。
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.

我开始在项目中使用它，但我无法得到 依赖注入工作（使用Unity）。我很喜欢 Razor，但缺乏智能感知确实降低了我的工作效率。
我现在坚持使用 MVC 2。当有更多关于 Razor 的文档可用时，我可能会升级到 3。

请查看这篇文章。如果您不关心 DI，那么您可能已经准备好了。唯一的其他变化是验证模型。
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.
