ASP.NET Core Web API and Swagger GUI

ASP.NET MVC and ASP.NET Web API previously had different types and configurations, but the Web API from ASP.NET Core is the same as the one from ASP.NET Core MVC. The Web API offers a simple communication technology based on Representational State Transfer (REST). With REST, HTTP verbs such as GET, POST, PUT, and DELETE are used. GET is used to retrieve resources, POST to add new resources, PUT to update resources, and DELETE to delete resources.
