The Windows namespaces (Windows.Foundation, Windows.UI, Windows.UI.Xaml, Windows.UI.Xaml.Controls.Primitives, Windows.UI.Xaml.Media, Windows.UI.Xaml.Media.Animation, and Windows.UI.Xaml.Media.Media3D) contain types for managing the user interface of your application.

This topic displays the types in the Windows namespaces that are included in the .NET for Windows Store apps. Note that the .NET for Windows Store apps do not include all the members of each type. For information about individual types, see the linked topics. The documentation for a type indicates which members are included in the .NET for Windows Store apps.
