Evergreen Webview2 -

Console.WriteLine($"Runtime updated to: e.NewVersion"); // Optionally reinitialize the WebView2 to get new features ; Pitfall 1: Assuming the Runtime is Always Present Many beginners assume Windows comes with WebView2. It does not (as of Windows 11 22H2, it's preinstalled, but on Windows 10 and older builds, it's missing). Always implement bootstrapper fallback. Pitfall 2: Mixing x86 and x64 The Evergreen runtime has both 32-bit and 64-bit versions. If your app is compiled for AnyCPU, you must ensure you initialize WebView2 using the correct architecture. Use CoreWebView2Environment.GetAvailableBrowserVersionString() to detect. Pitfall 3: Corporate Proxy and Firewalls Enterprise environments often block msedgewebview2 update endpoints. The runtime will fail to update silently. As a developer, either recommend that IT allow *.dl.delivery.mp.microsoft.com or consider switching to Fixed Version and deploying via SCCM. Pitfall 4: User Permissions The Evergreen runtime installs to %LocalAppData% for the current user or Program Files for machine-wide. If a user has strict applocker policies, the installation may fail. Test on locked-down environments. Part 9: The Future – WebView2 and Windows As of 2025, Microsoft is deepening its investment in WebView2. Windows 11 uses it extensively for Widgets, the Start Menu, and even parts of the Settings app. The Evergreen runtime is now automatically installed on all new Windows 11 devices.
