I have converted my Blazor Server-side Application to the new Blazor Web App project. Everything works as expected except for when I navigate to a view that does not exist.

I can reproduce what I am experiencing by creating a default Blazor Web App project in Visual Studio, launching via F5, and navigating to /somepaththatdoesnotexist (or any URL that does not exist).

What I experience is a blank white page.

What is the recommended configuration to restore the “not found” experience of the previous Blazor Server-side projects?
