 Alternatively, you can write the HTML to a <xref:System.IO.TextWriter> by calling `output.WriteHtmlTo(textWriter)`.
 
 The task returned by <xref:Microsoft.AspNetCore.Components.Web.HtmlRenderer.RenderComponentAsync%2A> completes when the component is fully rendered, including completing any asynchronous lifecycle methods. If you want to observe the rendered HTML earlier, call <xref:Microsoft.AspNetCore.Components.Web.HtmlRenderer.BeginRenderingComponent%2A> instead.
