Reactive Mobile Apps with GraphQL and Maui

GraphQL is designed for a mobile-first / cloud-first world and specifies how to expose modern APIs. GraphQL, since its inception, has been rapidly growing and is now the go-to solution for new APIs. The largest internet companies in the world like Facebook, Twitter, Netflix, and GitHub are all running on top GraphQL. Become part of this next shift in technology and learn why GraphQL has become so popular with companies of all sizes.

    In this workshop, we will introduce you to GraphQL and the major concepts behind it. We will look at how to build a GraphQL server with ASP.NET Core 7 and Hot Chocolate. You will learn how to query GraphQL and what tools are out there that can help you explore and manage large schemas. Further, we will dive into Maui and explore how to efficiently build fast and fluent mobile applications using Microsofts newest take on Mobile applications.
