In the modern landscape of Windows software development, building native applications that leverage web technologies (HTML, CSS, and JavaScript) is no longer just a trend—it's a necessity. has emerged as the premier control for this purpose, allowing developers to embed web content seamlessly into native desktop apps.
Always ensure the CoreWebView2 is initialized before calling methods that require it.
This pattern ensures that your application remains up-to-date with the latest security fixes and web platform features.
Microsoft is fully committed to the Evergreen model. As Windows 11 becomes ubiquitous, the WebView2 Runtime will be as common as the .NET Framework or VC++ Redistributable. By adopting Evergreen today, you ensure your app stays secure, fast, and compatible with the modern web for years to come.
During development or staging, use Windows Registry overrides to force your application to initialize using the Beta or Dev channel, allowing you to catch edge-case bugs weeks before they hit the general public. Conclusion
Be aware that the Evergreen mode, by design, does not allow you to specify a particular runtime version for your application. If your application requires strict version compatibility to function correctly (e.g., in a highly regulated industry or when embedded in specialized hardware), the Fixed Version distribution mode may be a more suitable choice.
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.
Only necessary for highly regulated environments (like banking or healthcare) where every single update must be manually validated by a QA team before deployment. In this mode, you bundle a specific version of the runtime, and it never updates. Implementation and Deployment
The Edge team constantly tunes the Chromium engine for better memory management and faster rendering. By staying "Evergreen," your application benefits from these performance boosts "for free." Evergreen vs. Fixed Version: Which to Choose?
Run automated UI and integration tests for your application against the WebView2 Beta channel.
If a security vulnerability is found in Chromium (which powers WebView2), Microsoft patches the Evergreen runtime automatically. You don't have to recompile, re-sign, or re-ship your app.
This is the standard, automatic-updating runtime. When you deploy an app that uses the Evergreen model, the WebView2 Runtime installs once on the user's machine. From that point forward, Microsoft silently keeps it up to date via Windows Update.
While Windows 10/11 comes with Edge, it is best practice to check if the WebView2 Runtime is installed. If not, use the bootstrapper to install it.
Developers typically choose between two primary deployment strategies:
To appreciate the Evergreen model, it helps to understand the two ways Microsoft allows you to distribute the WebView2 runtime with your app: Fixed Version Mode
While automated, certain issues may arise requiring manual intervention:
