 1. In this next step we want to refactor some code and generate a new record for our Weather API. The goal is to add a new record that includes the name of the city. We are going to achieve this by asking Copilot directly from the file using code comments. From the file pane, navigate to the following path `SampleApp\BackEnd\Program.cs` and open `Program.cs`.

Notice in the text box you can 'add context', which allows you to attach files, folders and other items to the context of Copilot so that it can better understand your codebase. Agent mode should be selected by default. You have the capability to choose your model as well. Also note, the open tab `Program.cs` is being referenced for context.
