Running the ASP.NET Core Web API project

Our ASP.NET Core Web API was created by Visual Studio 2017 IDE for the Windows environment and Yeoman generator for Linux/ macOS. We will run the application using either IIS Express or the Kestrel server.

Before running the application, let's understand more about the Values controller (created by default). Under the Controllers folder it has a C# class file named ValuesController.cs:

    using System.Collections.Generic; 
    using Microsoft.AspNetCore.Mvc; 
 
    namespace MyFirstCoreAPI.Controllers  
    {    
      [Route("api/[controller]")] 
      public class ValuesController : Controller 
      { 
        // GET api/values 
        [HttpGet] 
        public IEnumerable<string> Get() 
        { 
            return new string[] { "value1", "value2" }; 
        } 
 
        // GET api/values...
