Evergreen Webview2

The standalone installer also supports unattended installation:

A Fixed Version runtime adds roughly 150MB to 200MB to your application’s download size. If a user runs five different hybrid apps built this way, they waste nearly a gigabyte of storage on redundant Chromium binaries. Evergreen shares a single installation across the operating system, keeping your application installers lightweight and fast to download. Continuous Performance and Feature Evolution

If a user has five different apps installed that all use WebView2 Evergreen, they do not need five copies of Chromium. They share installation of the WebView2 Runtime. This saves significant disk space (hundreds of megabytes per app).

While the Evergreen runtime handles its own updates, a resilient WebView2 application requires the developer to plan for a few key scenarios. evergreen webview2

Because Evergreen WebView2 aligns with the Microsoft Edge update cadence, it receives rapid security patches. When a new vulnerability is found in the Chromium engine, your app is protected shortly after Edge updates, without requiring you to recompile or update your application. 2. Modern Web Standards

The runtime allows developers to embed web technologies (HTML, CSS, and JavaScript) into native applications, and deploying it via the Evergreen distribution mode ensures the underlying web platform updates automatically to keep apps secure, performant, and modern.

If the Evergreen runtime is corrupted, uninstalled, or blocked by Group Policy, your app fails to launch (error 0x8007007B ). You must handle graceful fallbacks or prompt to reinstall.

Multiple WebView2 applications on a machine share the same runtime, saving disk space.

Your app assumes the latest runtime. If Microsoft pushes a breaking change (e.g., deprecating a Web API), your app might break before you can update. However, this is extremely rare in practice. While the Evergreen runtime handles its own updates,

Upon installation, check if the runtime is already installed, and if not, trigger the installer.

is the recommended distribution model for developers looking to embed web content into native Windows applications. Unlike fixed versions, the Evergreen model ensures that the underlying web platform—powered by Chromium-based Microsoft Edge—stays current with the latest features, bug fixes, and security patches without requiring manual intervention from the developer. 1.
