Background Services in ASP.NET Core and .NET

on YouTube ↗01h 00m

" summary

Demonstrates turning a console app into a long‑running host using Microsoft.Extensions.Hosting, registers hosted work via BackgroundService, and shows the worker service template, container deployment, and new .NET 8 options to start/stop services concurrently. Builds a channel-based producer/consumer demo and a two‑service pipeline using S3 + SQS (localstack) that successfully moves upload processing off the request path. Covers gotchas: blocking start methods, fire‑and‑forget risks, synchronous work-before-first-await and Task.Yield as a workaround, plus the niche IHostedLifecycleService hooks.
