The document discusses new features in Visual Studio 2008, .NET Framework 3.5, and C# 3.0, including LINQ, ASP.NET enhancements, AJAX support, and language changes like var, extension methods, and object initializers. It also covers futures like the AJAX MVC framework and Silverlight 2.0. The presenter demonstrates examples in Visual Studio using the new C# 3.0 features and LINQ.

9. LINQ to SQL Code
using(var db = new PubsDBContext())
{
var authors = from a in db.authors
orderby a.au_id
select a;
foreach(var author in authors)
{
Console.WriteLine("{0} {1}",
author.au_fname, author.au_lname);
}
}

10. ASP.NET
 ASP.NET and IIS 7 share request pipeline
 AJAX a first-class part of web dev
 Support for AJAX WCF services

 Real JavaScript debugging
 Split UI for page design
 New CSS design tools
 Nested master pages

11. Futures

12. AJAX MVC Framework
 Real MVC Support
Controllers, Views, Models
Simplifies reuse and testing
Test project created automatically
 CTP delivery through development cycle
