Get started with GraphQL in .NET using C#
Created at Facebook in 2012 and released as open-source software in 2015, GraphQL has proven that it is here to stay. GraphQL is one of the "Big Three" when it comes to building modern APIs (alongside REST and gRPC), and it is the approach of choice for many big companies like GitHub, Shopify and thousands more. GraphQL solves many problems that developers encounter when building traditional REST APIs, and it does it with fashion, sporting an elegant read and write approach as well as a unique way to subscribe to data changes. In this 7-and-a-half-hour course, Michael Staib, a GraphQL steering committee member and creator of the popular GraphQL library HotChocolate, will assume you have no knowledge on this topic and take you to a very decent level where you'll be able to build GraphQL .NET applications using C#.
