Encapsulates the app and its available services.

Describes the visual structure of a data object.

Represents an object that participates in the dependency property system. DependencyObject is the immediate base class of many important UI-related classes, such as UIElement, Geometry, FrameworkTemplate, Style, and ResourceDictionary.

Represents a dependency property that is registered with the dependency property system. Dependency properties provide support for value expressions, data binding, animation, and property change notification.

Provides data for a PropertyChangedCallback implementation.

Provides a timer that is integrated into the Dispatcher queue, which is processed at a specified interval of time and at a specified priority. One scenario for this is to run code on the UI thread.

Provides event data for exceptions that are raised as events by asynchronous operations, such as MediaFailed or ImageFailed.

Provides a framework of common APIs for objects that participate in UI and programmatic layout. FrameworkElement also defines APIs related to data binding, object tree, and object lifetime feature areas.

Creates an element tree of elements.

Defines behavior aspects of a dependency property, including conditions it was registered with.

Implements a data structure for describing a property as a path below another property, or below an owning type. Property paths are used in data binding to objects.

Defines a dictionary that contains resources used by components of the app. This dictionary is oriented toward defining the resources in XAML, and then retrieving them through XAML references via the StaticResource markup extension. Alternatively you can access resources by traversing the dictionary at run time.

Contains state information and event data associated with a routed event.

Applies a value to a property in a Style.

Represents the base class for value setters.

Contains property setters that can be shared between instances of a type.

Defines a generated instance of a FrameworkTemplate.

Provides data for the TextChanged event.

UIElement is a base class for most of the objects that have visual appearance and can process basic input in a user interface.

Represents the visual appearance of the control when it is in a specific state.

Contains mutually exclusive VisualState objects and VisualTransition objects that are used to go from one state to another.

Manages states and the logic for transitioning between states for controls.

Represents an application window.

[SECURITY CRITICAL] Describes the characteristics of a rounded corner, such as can be applied to a Windows.UI.Xaml.Controls.Border.

Represents the duration of time that a Windows.UI.Xaml.Media.Animation.Timeline is active.

Represents the length of elements that explicitly support Windows.UI.Xaml.GridUnitType.Star unit types.

[SECURITY CRITICAL] Describes the thickness of a frame around a rectangle. Four System.Double values describe the Windows.UI.Xaml.Thickness.Left, Windows.UI.Xaml.Thickness.Top, Windows.UI.Xaml.Thickness.Right, and Windows.UI.Xaml.Thickness.Bottom sides of the rectangle, respectively.

Represents the method that will handle certain events that report exceptions. These exceptions generally come from asynchronous operations.

Represents the callback that is invoked when the effective property value of a dependency property changes.

Represents the method that will handle routed events.

Represents the method that will handle the TextChanged event.

Represents the method that will handle the Window.SizeChanged event.

Describes the kind of value that a Windows.UI.Xaml.GridLength object is holding.

Describes how a child element is vertically positioned or stretched within a parent's layout slot.

Specifies whether text is centered, left-aligned, or right-aligned.

Specifies whether text wraps when it reaches the edge of its container.

Describes how a child element is vertically positioned or stretched within a parent's layout slot.

Specifies the display state of an element.
