ASP.NET MVC 2 Beta Released!

Microsoft released ASP.NET MVC 2 Beta for Visual Studio 2008.

Lots of new changes in the beta so you will want to download the release notes along with new installer.

In particular, you will notice that RenderAction, AyncControllers, Expression-Based HTML Helpers, and other items that used to be in the ASP.NET MVC Futures Assembly have now been moved over to the core ASP.NET MVC Assembly

There has also been a pretty significant change to how TempData ( TempDataDictionary ) works with regarding to when keys expires. Now keys in TempData expire only when they are read and you can override this with a new Keep Method. Very interesting.

One should also notice that JsonResult only responds to HTTP Post Methods by default to avoid JSON Hijacking. You can override this if you so desire.

You can download ASP.NET MVC 2 Beta here.

Unfortunately, for those of you like myself who are using Visual Studio 2010 for new ASP.NET MVC Projects you will not have access to the new version for 2010 until there is a new release of Visual Studio 2010.

Have fun with it!
