Building a RESTful Minimal API with .NET Core 7

.NET Core and ASP.NET Core are robust frameworks used to create RESTful APIs, and this tutorial demonstrates their capabilities by guiding users through the development of a simple Minimal API that simulates credit score ratings. The Minimal API approach offers a streamlined method for building high-performing HTTP APIs with minimal setup, bypassing traditional scaffolding and controllers in favor of defining API routes and actions directly. The tutorial involves creating a simple API that generates random credit scores using a GET method and allows users to store and retrieve scores using POST and GET methods, respectively, without connecting to any external backend systems. The project setup includes using the .NET CLI to create a new web application, starting with a basic structure in Program.cs, and progressively adding functionality such as a CreditScore record type to handle score generation and user-added scores. The API is tested using Postman, and the tutorial concludes by suggesting further enhancements, including security and monetization options, to expand the API's functionality.
