You would have thought that after the latest version of the .NET Framework packed with its many new features the Microsoft .NET team would have sat back to enjoy their accolade, but this is not the case as they are still developing and have produced a number of extensions to the framework which will help developers add some of the functionality that usually takes allot of time to implement
For examples they have crated a MVC (Model-View-Container) framework and a new AJAX version, to mention just a couple of the new technologies ready for you to take advantage of.
To get the full information on these extensions please see Brad Abrams blog entry which also includes direction to tutorials.
