Always include a check in your app startup code to see if the WebView2 runtime is present. If it’s missing, direct the user to the download page or trigger the bootstrapper.
Evergreen is the recommended distribution mode for most developers. Microsoft encourages this approach across development scenarios because it allows applications to benefit from the latest security and platform fixes without per-app runtime management.
Developers historically faced a painful choice when embedding web content into desktop applications. They had to ship a massive, self-contained browser runtime or risk breaking the app when a user’s local browser updated.
Microsoft Edge WebView2 is a control that allows developers to embed web technologies (HTML, CSS, and JavaScript) into native applications. It uses as the rendering engine. This means your app can display web content with the same speed and compatibility as a modern browser like Chrome or Edge. The "Evergreen" Concept Explained evergreen webview2
The advantages of the Evergreen model over fixed-version or outdated web controls are significant: 1. Superior Security and Reliability
If a user does not have Edge installed? No problem. When your app installs, you call the simple (a tiny 1.5MB executable) that downloads and installs the Evergreen runtime silently in the background.

If you share with third parties, their policies apply. Can’t copy the link right now. Try again later. Always include a check in your app startup
Web vulnerabilities emerge constantly. With the Evergreen model, security patches reach your users immediately through Microsoft Edge release channels. You do not need to compile, test, and ship an emergency application patch just because of a newly discovered Chromium exploit. 2. Drastically Smaller Installers

While Windows 11 includes the Evergreen runtime by default, some enterprise clients or older Windows 10 systems might lack it or have updates blocked by corporate group policies.
As web standards evolve, the Evergreen runtime is updated to support them. You can use the latest APIs from the latest SDK, confident that the underlying platform will support them. 4. Better Performance
The bootstrapper downloads the runtime if missing. For offline/enterprise, you can chain the permanent standalone installer. No DLL hell.
