Windows provides APIs and capabilities for building desktop apps. Use these platform features to add native functionality—such as accessibility, on-device AI, notifications, and rich user interfaces—so your app integrates with Windows hardware and OS capabilities.
Windows platform features come from the Windows App SDK, the Windows SDK, and .NET. Browse the feature areas in this section to find the capabilities that fit your app, then follow the links to detailed guidance for each area.
