C# Techniques

Partial classesExtension methods and utility classesPreprocessor directives

#if SILVERLIGHT// Silverlight

#else// WPF

#endif

Source Layout

Peer folders for Silverlight & WPFFile links and source control

Silverlight\Control.csprojControl.csThemes\Generic.xaml

Wpf\Control.csprojControl.csThemes\Generic.xaml

Dependency Properties

Avoid WPF-specific metadataCoercionRead-only properties

Use WPF namespace

Watch out for the Silverlight 1.0 namespace
