winrt topic

Windows Runtime API

The Windows Runtime provides the latest generation of Windows APIs to apps running on Windows 8 or later. WinRT is an evolution of COM and the flat Win32 APIs that came before it, and is designed for projection into a variety of languages.

Classes

BatteryReport winrt Class
Provides properties that indicate the charge, capacity, and status of the battery.
Calendar winrt Class
Manipulates the representation of a DateTime within a given calendar and clock.

An associative collection, also known as a map or a dictionary.
ToastNotification winrt Class
UISettings winrt Class
Contains a set of common app user interface settings and operations.
UserDataPaths winrt Class
Returns full paths for common user data folders. User data folders are based on the KNOWNFOLDERID naming pattern.
ValueSet winrt Class
Implements a map with keys of type String and values of type Object. Object must be a WinRT PropertyValue or ValueSet. As a PropertyValue, it can be any type except PropertyType InspectableArray. This limitation exists to ensure that the value can be serialized; passed by value across a process boundary.
