Your Own Client

So far, you've only used a premade client to consume a Web API. However, for less popular APIs, there will not be any client for you to use. In those cases, you will have to make HTTP calls yourself. In .NET, the way of making calls has evolved quite a lot. If you don't want any third-party libraries, you can use the HttpClient class.

HttpClient

In this section, you'll repeat the GitHub Users example (from the Postman section), but this time using HttpClient. The flow for this is quite simple and is described for you in detail in the following example:

1. Within the GitHttp static class, create the GetUser method:

   public static async Task GetUser()

2. Within the GitExamples method, first, create a client:

   client = new HttpClient { BaseAddress = new Uri("https://api.github.com") };
   client.DefaultRequestHeaders.Add("User-Agent", "Packt");

Creating a client almost always involves specifying a specific base URL...
