LearnVisualStudio.net is a great site which provides thousands of videos on how to program in .Net. But you have to get subscribed to get access to their full set of videos. But occasionally they release free videos as well. You can get information about these free videos through email by subscribing. These are few free videos I received that way.

5) Understanding Web Application State
In this lesson, you will see how to maintain state in your ASP.NET 2.0 applications.
Not familiar with the term “state” as it’s used in web jargon?
Basically, the web is inherently a stateless environment … each “page” of a web site is independent. The trick is passing along certain information between each individual visit to a web page for a given user.
ASP.NET 2.0 has several different ways to accomplish this. In about 35 minutes we demonstrate and explain the major ASP.NET classes and various techniques you can use to provide your users a rich web-based experience.

6) Debugging and Tracing your Website
In this lesson, you will learn how to debug and monitor your ASP.NET 2.0 Web applications.
Fortunately, Microsoft has made it easy to step through each line of code to observe how it's executing to ferret out difficult-to-find bugs. Skills you've developed in writing Windows applications will definitely help, but there are some more tricks and tips that you can use with live applications (i.e., web applications that you've already deployed).
We'll show you almost everything you'll need to know about debugging and monitoring the execution of your app in less than 30 minutes!
