Setting a startup page in Blazor

The startup page in my Blazor application is Index.cshtml. I'd like to change the startup page to the homepage, namely my Home.cshtml.
I'm using vs2019, ASPNET CORE Blazor (0.9.0-preview3-19154-020).

Blazor Serverside has routing in the Startup.cs, which i think is for the services, and not for the pages...and is left as generated by creating a new Blazor project.

app.UseMvc(routes =>{   routes.MapRoute(name: "default", template: "{controller}/{action}/{id?}");});

The client's startup has (as generated by a new Blazor project):

public void ConfigureServices(IServiceCollection services){} public void Configure(IComponentsApplicationBuilder app){     app.AddComponent<App>("app");}

Do I need to register the routing in the client side startup.cs somehow?

the index.cshtml only has one line of code in it:

@page "/"

How do I change my 'startup' page from Index.cshtml to Home.cshtml?

I've looked in a lot of places and understand Blazor is 'experimental'. Feels like i'm working way to hard to change something this simple.
