There are two versions of MVC Futures that are next to RTM MVC 2. One version is for .NET 3.5; other goals of .NET 4. (.NET 4 is not a superset of .NET 3.5, you must include both of them in your application if you want the full range of functionality.) Download from http://aspnet.codeplex.com/releases/ view / 41742 .
A non-exhaustive list of functions (.NET 3.5+):
A diagnostic page that can help diagnose loading errors during runtime and build (see the documentation ).
New, more powerful model snapping and checking system . Detailed documentation and a tutorial are available at the above link.
Improved support for creating RESTful services (see Microsoft.Web.Mvc.Resources namespace).
Strongly typed ActionLink <T> () .
Many other filters and helpers such as Html.Serialize () (see blog post ), Html.Script (), etc.
Many providers of other values , such as JsonValueProviderFactory.
The ability to disable session state for individual controllers to increase parallelism on your site (see documentation ).
The ASP.NET 4-based MVC Futures version also includes:
The ability to have partial output caching , for example. caching the result of the RenderAction () separately from the rest of the page.
DynamicViewPage allows you to use real dynamic objects in ViewPage, somewhat more fully functional than the default ViewPage <dynamic>.
Ability to use DataAnnotations 4 attributes.
Remote validation , IClientValidatable (the ability of the validation attribute to provide its own client validation information) and the ability for custom non-DataAnnotations attributes to contribute to ModelMetadata information.
