Evergreen - Webview2 ((exclusive))

By not bundling the runtime with your application, your installer size is significantly smaller. Instead of packaging a

For the vast majority of applications, the Evergreen distribution mode is not only the recommended choice but also the most practical one. It reduces application size, ensures that security patches are applied swiftly, and allows developers to focus on building rich features rather than managing runtime infrastructure.

Leverage asynchronous APIs for navigation, script execution, and communication between the native host and the web content. This prevents the UI thread from being blocked and ensures that your application remains responsive.

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.

To ensure a smooth user experience, run the installer with silent arguments so the user isn't bombarded with extra installation wizards. By not bundling the runtime with your application,

on handling web-to-native communication (calling .NET methods from JS).

WebView2 comes in two primary modes of distribution:

Leverage the WebView2 Preview Channels (Beta, Dev, and Canary). Set up automated Continuous Integration (CI) pipelines to run UI automation tests against these pre-release channels. This gives you a multi-week warning before a breaking change hits your production users. Managing Runtime Availability If Microsoft pushes a breaking change (e

When your app launches, it checks if the WebView2 Runtime is installed.
