ASP .NET Basics for Experts

on YouTube ↗59m

" summary

Live demos show a .NET 7 web API for waffle orders using Minimal APIs and global using files to reduce top-level clutter, extension methods that move dozens of DI registrations out of Program, and three HTTP client styles: generic, named and strongly typed HTTP client wired to IHttpClientFactory. Resiliency uses Polly retry+circuit breaker policies against a local Azure Function rigged to fail — retries succeed on the 3rd try, the circuit opens and raises a BrokenCircuitException, and stays open for 10 seconds. Also covers Steeltoe discovery, and explains Singleton/Scoped/Transient lifetimes with live value comparisons.
