In c# complete the code in the TODO area of the code below. This can be done in any of the following ways. WebRequest and HttpWebResponse classes, a WebClient object, or an HTTPClient object.

In this lab, you will be writing your own C# web client that communicates to a web server and downloads a short message. There are multiple ways to implement the web client, a few of them being to utilize the WebRequest and HttpWebResponse classes, a WebClient object, or an HTTPClient object. Your web client should use a download method to contact the web server and display the server's response to the user. The template code already creates a working web server for you, so you'll only need to handle the client-side code.

Download the assignment template here. Submit the completed .cs file with your completed client code.
