Serverless GraphQL in .NET with Azure Functions and Hot Chocolate

on YouTube ↗01h 02m

" summary

Builds a .NET GraphQL server using Hot Chocolate on Azure Functions, shows configuring in-process vs isolated hosts to get cancellation/streams, and uses DB context pooling, EF Core queries with projection/filter/sort middlewares, and cursor pagination. Demonstrates real-time subscriptions delivered over SignalR/Azure SignalR Service or GraphQL SSE, with a publish-book mutation and a console subscriber that receives events. Covers cold-start, consumption vs premium plans, and using Redis/NATS for cross-instance pubsub; demos run and publish events successfully.
