Evergreen Webview2

– The Evergreen WebView2 runtime is the right default for most modern Windows apps. It offloads update management to Microsoft and keeps app size lean. Just ensure your app handles the missing-runtime scenario with a fallback or clear guidance. For mission-critical offline systems, use Fixed Version.

Since you cannot control exactly when a user’s runtime updates, your application might be running on a slightly different version of the web engine on User A’s machine compared to User B’s machine. While Microsoft maintains high backward compatibility, this introduces a variable into your QA process. You must ensure your web code is robust enough to handle minor version differences. evergreen webview2

: In the context of software and web development, "evergreen" refers to a browser or a piece of software that automatically updates itself to the latest version, ensuring that users always have the most current and secure experience. This approach contrasts with traditional software updates that require manual intervention. – The Evergreen WebView2 runtime is the right

Multiple apps share a single runtime, saving disk space and memory working set. For mission-critical offline systems, use Fixed Version

The term "Evergreen" signifies that the runtime is self-updating. Just like the Microsoft Edge browser, the Evergreen Runtime automatically updates itself independently of your application. It stays current with the latest security patches, performance improvements, and web standards compliance without requiring the developer to ship a new version of their app.

The runtime is Microsoft’s distribution model where a single, system-wide version of the WebView2 control is automatically updated (independently of your app). This contrasts with the Fixed Version (bundling WebView2 with your app).
