Blazor application shows error in console when Auto mode is used

I used Visual Studio latest preview with .NET8 RC1 to build a new Blazor App that allows Client and Server interactive components. By default, the app has its default rendering mode which I think is SSR.

In order to switch to the Auto mode, I used the following code as suggested by Microsoft (https://learn.microsoft.com/en-us/aspnet/core/blazor/components/render-modes?view=aspnetcore-8.0)

So I have this:

    <Routes @rendermode="@RenderMode.Auto"/>

in my App.razor file.

Although the app runs, I see this error in the browser console:

Uncaught (in promise) Error: System.InvalidOperationException: Root component type 'BlazorApp9.Components.Routes' could not be found in the assembly 'BlazorApp9'.
   at Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer.<UpdateRootComponents>g__AddRootComponent|8_0(RootComponentOperation operation)
   at Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer.UpdateRootComponents(String operationsJson)
   at Microsoft.AspNetCore.Components.RenderTree.WebRenderer.WebRendererInteropMethods.UpdateRootComponents(String operationsJson)
   at

If I use RenderMode.Server, I dont see this error.

I have not changed any code to the template provided by Visual Studio.

Any ideas?

Any interactive components (which is what you are making Routes by setting its RenderMode to Auto) must be moved to the webassembly/client project in RC1.

This is required because Routes must now be built in WASM and sent to the browser as part of the webassembly bits.
