Creating and implementing the TwitterAuthDetails class

In this section, we will create the TwitterAuthDetails class, which will essentially contain various properties and instance methods that will be used by our TwitterWebService class.

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

1. Ensure that the TrackMyWalks solution is open within the Visual Studio for Mac IDE.
2. Next, right-click on the Services folder, and choose Add | New File... from the pop-up menu, as you did in the section entitled Creating and implementing the LocationService class within Chapter 7, Adding Location-based Features Within Your App.
3. Then, choose the Empty Class option under the General section and enter TwitterAuthDetails for the name of the class to be created, as shown in the following screenshot:
