What's new in .Net Framework 3.0?

 Answer:

There are no major architectural changes in .Net Framework 3.0. The version of Common Language Runtime and .Net Compact Framework used in .Net Framework 3.0 is same as used in .Net Framework 2.0.

But .Net Framework 3.0 consists of following four new components:
1) Windows Presentation Foundation (WPF)
2) Windows Communication Foundation (WCF)
3) Windows Workflow Foundation (WF)
4) Windows CardSpace

WPF provides new features for making more interesting, effective, and dynamic user interfaces. Unfortunately these benefits come at a high price in performance. You will need a powerful computer with a large chunk of memory to run these applications effectively. However the benefits are big enough that it's likely that WPF will be an important new direction in Windows application development. Hopefully Visual Studio's WPF tools will improve greatly in Orcas.

Working with UAC is somewhat annoying in Visual Studio. You cannot request elevated privileges for a running application and you cannot easily launch a new thread or process with elevated privileges. Instead you must move any procedures that require elevated privileges into a separate executable and configure it to request UAC elevation. It would be nice if this got easier but I wouldn't count on it. UAC is still important enough and beneficial enough that you need to learn to work with it.

WCF, WF, and CardSpace are fairly complicated. It's not clear whether WF makes building workflow applications easier or harder. While WCF gives you lots of control and flexibility for building SOA applications, it's a lot harder than using a simple Web service. CardSpace is such an application-specific tool that I don't even know how to review it. If you need that functionality (I never have), perhaps you'll find it useful.
