Extensible Application Markup Language; pronounced "zammel") XAML is a declarative XML-based language that defines objects and their properties in XML. XAML syntax focuses upon defining the UI (user interface) for the Windows Presentation Foundation (WPF) and is therefore separate from the application code behind it. Although XAML is presently for use on the Windows platform, the WPF/E (Windows Presentation Foundation/Everywhere) initiative will eventually bring XAML to other platforms and devices.

XAMLBlogs.com is a site dedicated to aggregating blog entries about XAML. In an effort to provide more relevant links and to avoid duplications the aggregation is done by humans. Although this may sound time consuming, these humans are dedicated and already scouring the internet for references to XAML.
