Just after the ADO.net Entity Framework went into Beta 3, Scott Guthrie's team released the first CTP ASP.NET 3.5 extensions, which contain the MVC Framework (Model View Controller), ASP.NET AJAX Improvements, ASP.NET Silverlight Support, ADO.NET Data Services and ASP.NET Dynamic Data Support.
I have just finished installing it, since I'm really looking forward to the MVC framework. However, I'm not really sure as what to expect, since it really brings a new way of developing ASP.NET applications into play.
The installation gave me this strange but very honest error...
But, it ended up installing everything correctly, the extensions are showing up inside of the Project Template window.
I'm hoping to find some time to start exploring the new Silverlight controls...
All of this candy can be downloaded here.
Video's on using the MVC and other stuff included in this release can be found here.
