ASP.NET MVC Preview 4

ScottGu finally made it official after a long break (he was busy with his new born)... Preview 4 is relasing end of this week
Its a real good improvement with error filter, authorize filter,AccountController, and caching.

The authorize filter is more like declarative security model which lets you use attributes and filter actions(method) and classes based on your role. AccountController uses built in Asp.Net Membership provider and manage user credentials. You can also use your own custom logic and replace user account class with AccountController class.

Error Filter lets you display a friendly error page/response in case of exceptions.
One can also specify specific exception types like SQLException, NullReferenceException etc.

***ASP.NET Dynamic Data support will be included in MVC by end of Summer ***

Very cool high level features to use with ASP.MVC. The next previews will contain form validation, wizards to automatically create views and test class correspoding to a Controller. WAIT and Keep checking on my blog for upcoming releases.
