Evergreen Webview2 Patched -
The bootstrapper requires an active internet connection during installation [13†L43-L46]. Its small size makes it ideal for inclusion in online installers, where the primary application download is small, and the runtime is fetched only when needed. It also ensures the installation of the most recent version of the runtime.
Choosing Evergreen is often considered a "future-proofing" move for developers.
Evergreen WebView2 is a control component from Microsoft that allows developers to embed modern web content (HTML, CSS, and JavaScript) directly into native Windows applications. Unlike traditional "Fixed Version" distributions that bundle a specific browser version with the app, the model ensures the underlying web platform is always up-to-date and shared across all applications on a device. 🚀 Key Benefits of the Evergreen Model
Despite the runtime being preinstalled on many systems, it remains a best practice for developers to check programmatically whether the runtime is present and to include a fallback installation mechanism in their app installer to cover edge cases where the runtime might be missing or corrupted.
| Feature | Evergreen | Fixed Version | | :--- | :--- | :--- | | Automatic security updates | Yes (Microsoft) | No (You handle) | | App installer size | Small | Large | | Disk usage (per app) | Shared (~1 copy) | Duplicated (N copies) | | Control over version | Low (Microsoft decides) | Total (You decide) | | Works offline (air-gapped) | Requires pre-install | Yes (bundled) | | No admin rights required | No (system-wide) | Yes (app-local) |
Because the underlying browser engine updates independently of your application, defensive programming is essential to ensure long-term stability. 1. Handle Initialization Gracefully
. WebView2 provides rich interoperability features, including AddHostObjectToScript for exposing native objects to JavaScript and PostWebMessageAsString for sending messages between layers.
If you are building a Windows app with WebView2, understanding the "Evergreen" model is critical to deciding how your app will be distributed, updated, and maintained.
In this model, you download a specific version of the WebView2 Runtime and package it directly with your application.
