Dapr for building distributed .NET Core applications
summary
Builds a working Twitter hashtag monitor (filtering for #microsoft) in .NET Core 3.1 that streams tweets into a distributed pipeline: a Dapr sidecar handles a Twitter input binding, publishes events to Azure Service Bus, stores state in Redis state store, and updates a SignalR hub to push a live top‑10 leaderboard maintained by Dapr’s actor model. Runs locally with Docker Compose or Kubernetes, uses the Dapr CLI for sidecars, allows step‑through debugging, and successfully receives and processes live messages.
