what is the contribution of XAML Language?

Hi XAML learners,

What are the other areas of application development where XAML language contributing?

When writing .NET application, usually C# is not the only syntax you need to know. If you write WPF applications, use WF, create XPS documents, or write Silverlight applications, you also need XAML (eXtensible Markup Language). XAML is a declarative XML syntax that's usually needed with these applications.


Thanks.
