In chapters 13 through 19 you worked through each layer of a server-side rendered ASP.NET Core application, using Razor Pages and Model-View-Controller (MVC) controllers to render HTML to the browser. In part 1 of this book you saw a different type of ASP.NET Core application, using minimal APIs to serve JSON for client-side SPAs or mobile apps.
