This technique hasn't changed substantially since Dynamics AX 2012. The key difference is that we will need to manually craft the binding. We still need to create a C# project to consume the web service, and then use it as a reference within our F&O project.
The example service is a weather service provided by Open Weather (https://openweathermap.org/). There is no recommendation here. It was simply the first one I found when I searched for weather web services. The aim is to create a recipe that you can use for your web services. The chosen service, in this case, isn't relevant.
