Note that the DataChanged() method includes some asynchronous calls to Get() methods from a service class. These are the service classes in the shared library that are also used by the MVC and Razor Pages web apps in NetLearner. Note that the Startup class doesn’t have to be called Startup, but you do have to tell your application what it’s called. Instead, you just need a call to AddServerSideBlazor() in ConfigureServices() and a call to MapBlazorHub() in Configure() while setting up endpoints with UseEndPoints(). Razor Pages is the default for building server-side web applications in ASP.NET Core. Components within the underlying MVC framework still have their uses such as using controllers for building RESTful APIs.

However, Razor Pages removes a lot of the unnecessary ceremony that comes with the ASP.NET implementation of MVC and is a simpler, and therefore more maintainable development experience. If you choose to build your own, you can choose from a wide range of programming languages and frameworks. If you are a beginner, you will probably want to start with a framework and language that is easy to learn, well supported and robust. If you are considering making a career as a programmer, you probably want to know that the skills you acquire while learning your new framework will enhance your value to potential employers.
