Dotnet Core Expert

Summary

This one walks you through building .NET 8 apps with minimal APIs, clean architecture, and CQRS using MediatR. It's opinionated about async/await everywhere, nullable reference types enabled, and never exposing entities directly in responses. The workflow enforces actual compilation checks with dotnet build and running tests before you move forward, which catches issues early. Includes reference docs for EF Core, JWT auth, and cloud-native patterns. Best for greenfield microservices or API projects where you want modern C# 12 patterns baked in from the start. The constraint list is useful if you're tired of seeing synchronous database calls in reviews.
