Pro tip: In production, embed the bootstrapper as a resource or pre-download it on your server. Even though the runtime updates automatically, you aren’t completely hands-off. Updating Your SDK When Microsoft releases a new WebView2 SDK (e.g., new APIs or performance fixes), you should update your NuGet package and recompile. The new SDK might rely on features or performance guarantees from newer runtimes. Your app will still run on older Evergreen runtimes (down to the minimum version you set), but to use new APIs, you need a newer runtime. Minimum Version Strategy Set CoreWebView2EnvironmentOptions.TargetCompatibleBrowserVersion if you require a specific baseline.

Furthermore, Microsoft has announced that the legacy WebBrowser control will be permanently disabled in future Windows releases. For line-of-business applications still using VB6 or WinForms with IE, migration to Evergreen WebView2 is not optional—it’s a necessity. Evergreen runtime supports Windows 7 ESU (Extended Security Updates) as well. However, on legacy OS, the runtime won’t auto-update if the OS itself is out of support. Plan accordingly. Part 10: Conclusion – Evergreen is the Default Choice To wrap up: Evergreen WebView2 is Microsoft’s strategic solution for hosting web content in native apps. It combines the best of both worlds: the rich capabilities of Chromium with the deployment simplicity of automatic updates. Pro tip: In production, embed the bootstrapper as

Introduction In the modern landscape of Windows application development, developers face a recurring dilemma: how to embed rich, up-to-date web content without shipping a full browser or relying on the inconsistent, aging Internet Explorer engine. The new SDK might rely on features or

WebView2 is a control that allows developers to embed Chromium-based Microsoft Edge into desktop applications. Unlike its predecessor, the WebBrowser control (which used Internet Explorer), WebView2 complies with modern web standards, supports features like WebRTC, Service Workers, WebGL, and receives security updates via Edge's lifecycle.
