This article provides an index of development features that are related to scenarios involving managing the lifecycle of Windows apps and using system-level services provided by the Windows OS.
Windows App SDK features
The Windows App SDK provides the following features related to app lifecycle and system services for Windows 10 and later OS releases.
If you're working on a UWP app, refer to Migrate from UWP to the Windows App SDK.
|App instancing||Control whether multiple instances of your app's process can run at the same time.|
|Rich activation||Receive information about different kinds activations for your app.|
|Power management||Get visibility into how your app affects the device's power state, and enable your app to make intelligent decisions about resource usage.|
Windows OS features
Windows 10 and later OS releases provide a wide variety of APIs related to app lifecycle and system services for apps. These features are available via a combination of WinRT and Win32 (C++ and COM) APIs provided by the Windows SDK.
The following articles provide information about features available via WinRT APIs provided by the Windows SDK.
