Communication features enable Windows apps to share data, connect over networks, and interact with other applications. This article provides an index of development features for implementing communication scenarios in Windows apps.
Note
The Windows App SDK currently does not provide APIs related to communication scenarios. However, in Windows 11 you can share data between apps by integrating with the Windows Share Sheet in packaged and unpackaged desktop apps.
Windows 10 and later OS releases provide a wide variety of APIs related to communication scenarios 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.
