The ConfigureServices() calls AddMvc() to add the required services to DI container. The Configure() then calls UseMvcWithDefaultRoute() to add MVC middleware with default routing configured for us. In spite of these differences you can create a single project that makes use of these three development options. Core features such as model binding, DI, sessions, and cache can be utilized in Razor Pages as well as MVC in the same way.
