Silverlight: The XAML Part of It

The Designer-Developer Workflow: How XAML acts as the bridge between design and logic, enabling designers to craft rich interactions in Expression Blend while developers handle the backend in Visual Studio without breaking each other's code.

Declarative vs. Imperative: Moving away from constructing UIs in code-behind to defining structures declaratively, allowing for cleaner hierarchy visualization and easier management of complex layouts like Grids and StackPanels.

Data Binding & MVVM: Leveraging XAML’s powerful binding engine to decouple the UI from business logic, ensuring that view updates happen automatically through property notification rather than manual event handling.

The Visual State Manager (VSM): Going beyond basic styling by defining complex, animation-rich visual states (Normal, Hover, Pressed) directly in markup, keeping interaction logic separate from the core application functionality.
