How XAML is related to WPF?
XAML is a new descriptive programming language developed by Microsoft to write user interfaces for next generation managed applications. XAML is used in WPF to represent the controls and code with the help of C#, Visual Basic, and other .NET Framework languages.
XAML can be think as ASP.NET and/or Windows Forms in Windows Vista. For example, to write a Web application in .NET 1.0, 1.1, or 2.0, you use ASP.NET and to write Windows Applications, you use Windows Forms. Now in Windows Vista and .NET 3.0, you will use XAML instead of Windows Forms and ASP.NET.
Does that mean XAML will replace ASP.NET and Windows Forms?
YES and NO. Both ASP.NET and Windows Forms will also be supported on .NET 3.0 but you don't have to use them if you don't want.
What Operating Systems does WPF support?
Windows Vista, Windows XP, and Windows 2003 Server.
