Define a Blazor Page using .razor.cs file only; no .razor file

Question

I was hoping the "Test.razor.cs" file below (with no corresponding "Test.razor" file hence no "partial" ) would actually work as a Page for example. But I get the "Sorry, there's nothing at this address." error when going to ".../Test"

using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Rendering;
using NorthWind.UI.Shared;

namespace NorthWind.UI.Pages
{
    public class Test : ComponentBase
    {

        protected override void BuildRenderTree(RenderTreeBuilder builder)
        {
            builder.OpenComponent(0, typeof(SurveyPrompt));
            builder.AddAttribute(1, "Title", $"Some Test");
            builder.CloseComponent();

            base.BuildRenderTree(builder);
        }
    }
}

Is there a way to add it to the pages that Blazor can evaluate too (other than adding a front end .razor file )?

Answer 1

The Answer is to add the Microsoft.AspNetCore.Components.RouteAttribute to the class

    [Route("/Test")]
    public partial class Test : ComponentBase
    {

        protected override void BuildRenderTree(RenderTreeBuilder builder)
        {
            builder.OpenComponent(0, typeof(SurveyPrompt));
            builder.AddAttribute(1, "Title", $"Some Test");
            builder.CloseComponent();

            base.BuildRenderTree(builder);
        }
    }
