ASP .NET Basics for Experts
summary
Demonstrates .NET 6 features by building a waffle API with code on GitHub (Layla-hyphen-P): adoption of Minimal APIs, top‑level statements and global usings, refactoring registrations into IServiceCollection extension methods, and explicit use of dependency injection. Shows HTTPClientFactory patterns (generic, named, strongly typed), adds Polly policies — retry, fallback and a Polly circuit breaker set to three failures — and observes the circuit open and block calls. Mentions Steeltoe OSS for discovery and that the demo runs live.
