.NET Aspire: Let's build a cloud application with baked in observability
summary
Claim: .NET Aspire provides an opinionated developer stack that ships OpenTelemetry baked in so logs, metrics and traces are automatically collected and sent to a local OTLP endpoint and dashboard. Demo wires a Blazor site → API → RabbitMQ → worker, plus Redis cache and Postgres, uses environment-variable service discovery and built-in retry/resilience. Deployment proof-of-concept pushes the same app to Azure Container Apps via azd. Everything runs locally and in Azure for the demo (minor network hiccups noted), showing end-to-end traces, metrics and logs.
