+Due to changes in the framework across releases of ASP.NET Core, Razor markup for the `App` component (`App.razor`) isn't shown in this section. To inspect the markup of the component for a given release, use ***either*** of the following approaches:
+
+* Create an app provisioned for authentication from the default Blazor WebAssembly project template for the version of ASP.NET Core that you intend to use. Inspect the `App` component (`App.razor`) in the generated app.
+* Inspect the `App` component (`App.razor`) in [reference source](https://github.com/dotnet/aspnetcore/blob/main/src/ProjectTemplates/Web.ProjectTemplates/content/ComponentsWebAssembly-CSharp/Client/App.razor).
