If you are writing a post or developing an app, keep these mechanics in mind:

This tells Evergreen: "Only use runtimes >= version 1.0.1245.22."
While the Evergreen runtime handles its own updates, a resilient WebView2 application requires the developer to plan for a few key scenarios. In the Electron era, a user with five

Write defensive code. If the WebView2 runtime is missing or corrupted, display a user-friendly error message or a download link instead of crashing. If you are writing a post or developing
In the "Fixed Version" model, if a major security flaw is found in Chromium, you have to patch your app, recompile it, and push an update to every user. With Evergreen, Microsoft handles the update. As soon as Edge is patched, your app is protected. 2. Smaller Installer Sizes
