ASP.NET Core's Built-in Dependency Injection Framework
summary
Covers ASP.NET Core’s built‑in DI with concrete details: explains singleton scoped transient lifetimes, shows thread‑safe RequestIDFactory registered as a singleton producing incrementing IDs while RequestID is scoped per HTTP request, and the demo proves IDs persist across tabs and increment correctly. Shows how to hook Autofac (RegisterType and lifetime chaining) and StructureMap, and warns Ninject requires the community “missing DI extensions” workarounds and won’t cleanly inject into views.
