+WinAppSDK supports custom WebView2 environments, starting with WinAppSDK 1.5 ([1.5.0-experimental2](/windows/apps/windows-app-sdk/experimental-channel#version-15-experimental-150-experimental2)).  For more information, see [WinUI3 WebView2 with a custom CoreWebView2Environment](https://github.com/microsoft/microsoft-ui-xaml/issues/6150).
+
+To instantiate a custom WebView2 environment, initialize WebView2 with one of the overrides of `WebView2.EnsureCoreWebView2Async` (listed below), and pass in your custom `CoreWebView2Environment` (and, optionally, custom `CoreWebView2ControllerOptions`):
+
+```csharp
+public IAsyncAction EnsureCoreWebView2Async (CoreWebView2Environment environment)
+public IAsyncAction EnsureCoreWebView2Async (CoreWebView2Environment environment, CoreWebView2ControllerOptions controllerOptions)
+```
+
+Also see the example code in [Disabling SmartScreen navigation](#disabling-smartscreen-navigation), below.
