In this mode, the WebView2 Runtime is not packaged within the app. Instead, it is installed once on the client machine via an online bootstrapper or an offline installer. Afterwards, it is automatically updated by Microsoft, ensuring users always have the latest security patches and features. This mode reduces disk space usage and maintenance overhead because a single shared instance supports all WebView2 apps on a system.
