Summary
In this chapter, we explored how to use HotChocolate and Entity Framework Core to create a GraphQL API. We discussed how to define object types, queries, and mutations, as well as how to use dependency injection to inject the DbContext instance and services into the resolver. We also introduced the data loader, which can reduce the number of queries to the database. Additionally, we discussed interface and union types, which are useful for defining polymorphic types. Finally, we explored how to use filtering, sorting, and pagination in HotChocolate.
In the next chapter, we will discuss SignalR, which is a real-time communication library in ASP.NET Core.
