About this tag
Package identity is a core concept in Windows app development, particularly for Universal Windows Platform (UWP) applications. It uniquely identifies a packaged application and is required for accessing certain Windows 10 APIs, such as those for notifications, background tasks, and device capabilities. In Windows 11, package identity also plays a role in security and privacy enhancements, enabling features like app isolation and controlled resource access. Developers working with desktop applications (WPF, WinForms, MFC) can leverage package identity through the Desktop Bridge to integrate UWP APIs. Understanding package identity is essential for building modern, secure Windows applications that comply with evolving platform requirements.
