Add WebView2

Add WebView2 only when the product needs embedded web content.

Add The Control

<Grid>
    <WebView2 x:Name="DocsView" />
</Grid>

Initialize and apply navigation policy:

await DocsView.EnsureCoreWebView2Async();
DocsView.CoreWebView2.NavigationStarting += (_, args) =>
{
    var allowed = args.Uri.StartsWith("https://docs.example.com/", StringComparison.OrdinalIgnoreCase);
    args.Cancel = !allowed;
};
DocsView.Source = new Uri("https://docs.example.com/");

Choose Runtime

Choice	Default?	Notes
Evergreen	Yes	Best security/update path for most apps
Fixed Version	No	Use for strict compatibility/offline requirements and update it deliberately

Test

Native shell still launches without elevation.
Navigation policy blocks unexpected origins.
Web content can be smoke-tested with Playwright if complex.
Runtime availability is tested on a clean machine or documented as installer responsibility.
