New Project, Templates (In VS Community 2017, Visual C# is the top level), Visual C#, Web:
	select "ASP.NET Web Aplication (.NET Framework)"
	select Web API

To Add A Controller: Solution Explorer, right click the project, add, new item, Visual C#, Web, Web API
	Make sure to include "Controller.cs" at the end of whatever word you choose to make it unique.

Next add an html page:  solution explorer, right click the project, add, HTML Page:
	Inside the page, paste (inside the body tag):
	
	<div id="div1"><h2>Let jQuery AJAX Change This Text</h2></div>
	<button>Get External Content</button>

	<script src="http://code.jquery.com/jquery-2.2.4.min.js"></script>
	<script>
		$(document).ready(function(){
			$("button").click(function(){
				$("#div1").load("api/Basic/Get/0");
			});
		});
	</script>

GET, POST, PUT, DELETE  (REST methods):  Let's setup the mappings to the controller:

Solution Explorer, App_Start folder, WebApiConfig.cs, add these mappings:
			config.Routes.MapHttpRoute(
				name: "DefaultApi",
				routeTemplate: "api/{controller}/{id}",
				defaults: new { action = "Get", id = RouteParameter.Optional },
				constraints: new { id = @"\d" }
			);
			config.Routes.MapHttpRoute(
				name: "BasicActionRoute",
				routeTemplate: "api/{controller}/{action}/{id}",
				defaults: new { id = RouteParameter.Optional },
				constraints: new { id = @"\d" }
			);
