ASP.NET Basics for Experts
summary
Migrates a .NET 5-style Startup into .NET 6 top-level statements and minimal hosting, showing code on GitHub (Layla-P/BasicsForExperts-CodeEdition) and a live waffle demo that uses an Azure Function ingredients API. Implements managed clients with builder.Services.AddHttpClient and strongly typed clients, wraps them with Microsoft.Extensions.Http.Polly policies (retry, fallback, circuit breaker), and demonstrates a circuit breaker trips after 3 failures when the API returns 500. Organizes registrations via IServiceCollection extensions and uses user secrets for connection strings.
