个人做的摘记了，懒得翻译，大家自己看吧。

Razor （一个集成的新的View Engine，使代码简洁了不少。）

JavaScript Improvements

Improved Validation

Output Caching

除了支持在url 或 action-method级别的支持外，新增对页面部分(partial page)的output支持（类似于以前的

asp:Substitution控制的功能）

Previous releases of ASP.NET MVC supported output caching content at a URL or action-method level

With ASP.NET MVC V3 we are also enabling support for partial page output caching

Better Dependency Injection

You can instead just register a Dependency Injection framework with ASP.NET MVC 3

之前是需要自己去定一个类来做这个DI工作，现在只需要简单注册下类就好了。

以下是更多的新功能：

ASP.NET MVC 3 includes dozens of other nice improvements that help to both reduce the amount of code you write, and make the code you do write cleaner. Here are just a few examples:

Improved New Project dialog that makes it easy to start new ASP.NET MVC 3 projects from templates.
Improved Add->View Scaffolding support that enables the generation of even cleaner view templates.
New ViewBag property that uses .NET 4’s dynamic support to make it easy to pass late-bound data from Controllers to Views.
Global Filters support that allows specifying cross-cutting filter attributes (like [HandleError]) across all Controllers within an app.
New [AllowHtml] attribute that allows for more granular request validation when binding form posted data to models.
Sessionless controller support that allows fine grained control over whether SessionState is enabled on a Controller.
New ActionResult types like HttpNotFoundResult and RedirectPermanent for common HTTP scenarios.
New Html.Raw() helper to indicate that output should not be HTML encoded.
New Crypto helpers for salting and hashing passwords.
And much, much more…
