- How you develop your client
applications?
One set of technologies—based on HTML, DHTML,
Asynchronous JavaScript and XML (Ajax), and Microsoft
ASP.NET Atlas
gives you the same level of sophistication that a “heavy” client
can give you using “light” technologies
The other approach: WPF
including a declarative XML markup language named Extensible
Application Markup Language (XAML) that defines the user
interface, but has an incredibly powerful runtime supporting it
Microsoft 9
- The Windows SDK
The Windows SDK contains all the APIs for developing
next-generation Windows applications
provides the foundation for software development for the
Windows server and client platforms for the foreseeable future
The Windows SDK is centered on the .NET Framework
3.0, sometimes called NetFX
which contains the classes you are familiar with from the .NET
Framework 2.0 in addition to WPF, WCF, and WWF

Also usable for your own purposes
No more choosing between C# or VB.NET

- XAML vs. Code
XAML and code can do the same thing
Xml tag

object
to another object
