Creating and implementing the TwitterWebService class

In this section, we will create the TwitterWebService class that will inherit from our ITwitterWebService interface and implement the underlying instance methods that we declared within our interface class. They will help us to communicate with our app that we created within the Twitter Developer Portal.

Let's start by creating the TwitterWebService class for our TrackMyWalks app by performing the following steps:

1. Firstly, right-click on the Services folder and choose Add | New File... from the pop-up menu.
2. Next, create a new Empty Class called TwitterWebService within the Services folder, as you did in the section entitled Creating and implementing the TwitterAuthDetails class, located within this chapter.
3. Then, ensure that the TwitterWebService.cs file, which is located within the Services folder, is displayed within the code editor, and enter the following code snippet:

    //
    //  TwitterWebService.cs
    //  TwitterWebService Class...
