How do I use HttpClient?

The general process for using HttpClient consists of a number of steps:

1. Create an instance of HttpClient .
2. Create an instance of one of the methods (GetMethod in this case).
3. Tell HttpClient to execute the method.
4. Read the response.
5. Release the connection.
6. Deal with the response.

HttpClient is fully thread-safe when used with a thread-safe connection manager such as MultiThreadedHttpConnectionManager. At the same time the HttpClient instance and connection manager should be shared among all threads for maximum efficiency.

HttpClient is able to process multiple concurrent requests. It is a layer over HttpWebRequest and HttpWebResponse. All methods with HttpClient are asynchronous. In this example, I have created a console application. To call Web API methods from the console Application, the first step is to install the required packages, using NuGet Package Manager.

I am calling an external service using HttpClient from within an ASP.Net MVC 4 Web Api project running on .Net Framework 4.5 The sample code is as follows (ignore the return values as this is sample code to test calling an external service):

Background We all use Web API in our applications to implement HTTP services. HTTP services are much simpler if we use Web API, but, the fact is, the benefits of using Web API are not limited to that. Previously, we’ve used WCF services instead of Web API, when we were working with endpoints.
