Your WinForms app needs to log into Azure AD or Google. Instead of spinning up a separate browser or writing custom HTTP listeners, you embed a tiny WebView2, point it to https://login.microsoftonline.com . Evergreen ensures that the latest security headers, cookie policies, and FIDO2 (passkey) support are available. You never have to update your identity code.
When using the Evergreen model, you should never assume a specific API is available based on a runtime version number. The automatic update cycle means runtime versions can vary across client machines. The robust strategy is to always use : programmatically check for the existence of a specific method or property before attempting to use it. This ensures your app gracefully degrades or adapts its functionality on older runtimes, maintaining stability across all supported environments.
On Windows 10 (latest versions) and Windows 11, the Evergreen Runtime is typically already there, making the user experience seamless. Best Practices for Developers
WebView2 offers two main distribution modes: and Fixed Version 1.2.1. While Fixed Version allows you to bundle a specific version of the runtime with your app, Evergreen is preferred for most scenarios. Evergreen WebView2 Fixed Version WebView2 Updates Manual (by app developer) Security Always up-to-date Requires manual patching Disk Space Shared (efficient) Independent (bloated) Compatibility High (latest web standards) Strict control (for specific bugs) Best For General Applications Kiosks, Regulated Systems Advantages of Evergreen:
Evergreen WebView2 is a runtime environment that allows developers to embed a modern web browser, specifically Microsoft Edge, into their desktop applications. This enables the use of web technologies such as HTML, CSS, and JavaScript to build desktop applications.
Enter . Since its general availability in 2020, WebView2 has revolutionized how developers integrate web technologies (HTML, CSS, JavaScript) into native Windows applications (WinForms, WPF, WinUI 3, and even console apps).

Let’s get practical. Here is how you set up an Evergreen WebView2 in a common scenario: a .NET 8 WPF application.
The term "evergreen" in software refers to a product that updates itself automatically in the background, without user intervention or manual downloads. Your web browser, whether Chrome, Firefox, or Edge itself, is evergreen. It silently updates to the latest version, bringing new features, performance improvements, and—most importantly—security patches.
The mode is the recommended default for most applications because it reduces the developer’s burden to ship security updates and ensures users always have a compliant, up-to-date web platform.
While rare, automatic updates can occasionally cause issues. Developers are encouraged to test their apps against Microsoft Edge Preview channels (Beta, Dev, or Canary) to catch upcoming changes. ⚠️ Common Hurdles
For enterprise apps that require absolute consistency (e.g., kiosk systems, strictly regulated industries), Microsoft offers the "Fixed Version" distribution mode. This allows you to package a specific version of the WebView2 Runtime inside your app, freezing it in time. This sacrifices the benefits of auto-updating in exchange for stability.
