Dotnet Backend
This is your go-to for building ASP.NET Core 8+ APIs when you need more than just CRUD routes. It handles the full backend stack: EF Core with proper query optimization (AsNoTracking, eager loading), JWT auth with policy-based authorization, background workers using IHostedService, and production patterns like global exception handling and response caching. The code examples are solid and modern, covering both Minimal APIs and controller-based approaches. It won't help with .NET Framework projects or deployment specifics, but if you're spinning up a new API or refactoring an existing one with Entity Framework, authentication, or scheduled jobs, this gives you the enterprise patterns without the boilerplate hunting.
