With .NET we often use WebAPI services. These services are most of the time based on the Restful principle. However, for a few years, GraphQL has been gaining popularity. Listening to talks about a topic can give you a good overview of what a technology stack can do. But playing with new technology will help you gain far better insights. So in this workshop, you are going to build your own GraphQL Service in .NET using Visual Studio or Jetbrains Rider. Because of the code, you will have to write, some basic understanding of .NET is required and of course, you do need your laptop with Visual Studio or Jetbrains Rider installed with of course the latest version of .NET.
