 By default, an ASP.NET Core app doesn't provide a status code page for HTTP error status codes, such as *404 - Not Found*. When the app sets an HTTP 400-599 error status code without a body, it returns the status code and an empty response body. However, an app generated from the Blazor Web App project template calls <xref:Microsoft.AspNetCore.Builder.StatusCodePagesExtensions.UseStatusCodePagesWithReExecute%2A> to add Status Code Pages Middleware to the request pipeline for pages that aren't found, which generates the response body by re-executing the request pipeline using the path to the Not Found error page (`/not-found`): 
 
 ```csharp
-app.UseStatusCodePagesWithReExecute("/not-found", createScopeForStatusCodePages: true);
+app.UseStatusCodePagesWithReExecute("/not-found", 
+    createScopeForStatusCodePages: true);
