The is a redistributable component that acts as the underlying web platform for WebView2 applications. Unlike older web technologies that relied on the installed (and often outdated) version of Internet Explorer (MSHTML), WebView2 is powered by the Microsoft Edge (Chromium) engine.

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

: Since the runtime is shared across all applications using the Evergreen mode, it saves significant disk space compared to the "Fixed Version" mode, which requires a dedicated copy for every app Microsoft Learn Hard-linking

This model offers precise version control—you know exactly which WebView2 APIs are available because you control which version of the runtime is used. However, it comes with significant trade-offs: you must manage the runtime yourself (it doesn't auto-update), each installed WebView2 application consumes its own disk space for the runtime, and you cannot install the fixed version runtime using a traditional installer. // Example in WPF await webView

Your app supports the latest CSS, HTML5, and JavaScript features, allowing for a better user experience.

Microsoft Edge WebView2 is a control that allows developers to embed web technologies (HTML, CSS, and JavaScript) into native applications. It uses as the rendering engine. This means your app can display web content with the same speed and compatibility as a modern browser like Chrome or Edge. The "Evergreen" Concept Explained Unlike older web technologies that relied on the

The Evergreen Runtime works by leveraging the existing Microsoft Edge installation on modern Windows 10/11 machines. If the runtime is missing, the app can initiate a light bootstrapper installer. The Deployment Process:

. WebView2 provides rich interoperability features, including AddHostObjectToScript for exposing native objects to JavaScript and PostWebMessageAsString for sending messages between layers.
