Building GraphQL APIs in C#
summary
Claims that GraphQL cuts client-server round trips and lets clients shape responses get demonstrated with concrete tools and code: uses .NET 6 ASP.NET Core, adds Hot Chocolate via NuGet, calls AddGraphQLServer().AddQueryType() and MapGraphQL() to expose a one endpoint POST API whose body contains a JSON field named query. Demo builds Book and Author records, implements getBooks and getBook, and exercises them with GraphiQL/Banana Cake Pop and Postman; it returns exact JSON fields as requested (server briefly crashes once during the demo).
