Evergreen Webview2 Jun 2026

While the Evergreen model is the standard, developers should be aware of a few logistical factors:

The Evergreen model's automatic update capability is its defining characteristic. After the initial installation, the WebView2 Runtime is automatically updated on client machines, ensuring that all WebView2 applications benefit from the latest security patches and performance improvements without any additional effort from developers.

: Use CreateCoreWebView2Environment (C++) or EnsureCoreWebView2Async (.NET) without specifying a browser executable folder. This tells the app to look for the system-installed Evergreen runtime.

To fully leverage the power of the Evergreen model, follow these best practices: evergreen webview2

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

The standalone installer also supports unattended installation:

For power developers, here are two advanced patterns. While the Evergreen model is the standard, developers

(Note: As per policy, I cannot provide direct download links to executable binaries, but the official Microsoft site is the definitive source.)

For secure environments without internet, Evergreen is problematic. You need the Fixed Version model (ship WebView2 with your app) – which defeats the "evergreen" benefit.

If you have ever maintained a CEF (Chromium Embedded Framework) or Electron app, you know the pain of the "massive bundle." Let’s compare the developer experience. This tells the app to look for the

In Fixed Version mode, you download a specific version of the WebView2 Runtime binaries and package them directly inside your application installer.

In the modern landscape of software development, the line between native desktop applications and web experiences has blurred. Developers want the speed and ubiquity of web technologies (HTML, CSS, JavaScript) paired with the robustness and OS integration of native applications.
