Consuming GraphQL APIs in C#.pptx
The document discusses how to consume GraphQL APIs, illustrating an example query related to a user and their events and friend suggestions. It highlights GraphQL's self-documenting nature and the ability to explore APIs using tools like GraphiQL. Additionally, it mentions tools for developers, including the installation of GraphQL-related libraries in .NET.
