If you're deploying your application as an MSIX package, you can specify the WebView2 Runtime as a dependency to have it installed alongside your application. This approach handles all prerequisite logic automatically and provides a seamless installation experience.

The is the recommended distribution mode for Windows applications, ensuring your app always uses the latest, most secure version of the Chromium platform. Unlike the "Fixed Version," the Evergreen runtime is not packaged with your app; instead, it is installed once on a client machine and updated automatically by Microsoft. 1.

: Applications automatically receive the latest security patches and feature updates without developer intervention. Reduced Disk Footprint

On supported systems, the Evergreen Runtime binaries are hard-linked with Microsoft Edge, optimizing both memory usage and disk space.

Microsoft is also introducing WebView2 support for Entra ID sign-ins on Windows 11, enabling faster, more secure authentication flows that pave the way for passwordless login and advanced identity features. As Microsoft stated, "Authentication is the front door to your digital world. As identity experiences evolve, we need a foundation that supports modern web standards, advanced security, and future-ready scenarios. WebView2 provides exactly that".

In the Electron era, a user with five desktop apps had five separate Chromium runtimes on their SSD, each occupying 150MB. That’s 750MB of pure duplication. Each app had its own updater, its own crash reporting, and its own separate sandbox processes.

For enterprise apps that require absolute consistency (e.g., kiosk systems, strictly regulated industries), Microsoft offers the "Fixed Version" distribution mode. This allows you to package a specific version of the WebView2 Runtime inside your app, freezing it in time. This sacrifices the benefits of auto-updating in exchange for stability.

One of the most compelling aspects of the Evergreen distribution model is its deep integration with the Windows operating system. The Evergreen Runtime is preinstalled on as part of the operating system itself. Microsoft has also distributed the WebView2 Runtime to all eligible Windows 10 devices through Windows Update, meaning that a vast majority of Windows users already have the required runtime installed before your application ever reaches their machine.
