• Instead of writing the data access code to populate a DataGrid, you can now declaratively associate it with any number of DataSource controls, which manage the details of data access for you.

• Instead of manually checking your SQL Server for new data, use the new SqlCacheDependency to invalidate your cached data when the underlying data changes

• Instead of building custom login forms for your application’s forms
authentication, you can now drag an instance of the Login control onto a page and hook it up to the functions of the Membership class.

• Instead of manually inserting User controls into each page of your
application you can consolidate them in a single ‘Master Page’ template.

• Instead of building your own infrastructure for easily changing the
appearance of your entire site you can now define skins and apply themes generically.

With more than 40 new server-side controls and many new pieces of
Web infrastructure, ASP.NET 2.0 delivers more new features than any Web development technology in recent memory. You will come away with a solid understanding of the new features in ASP.NET 2.0, and be prepared to make the right design and implementation choices when you make the switch to ASP.NET 2.0
