How do you use Factory Pattern alongside DI?

Updated Apr 28, 2026

Short answer

When you need to construct objects at runtime using data unknown at startup, DI injects a Factory rather than the object itself.

Deep explanation

DI containers are great for wiring static graphs. But if an object requires dynamic parameters (like a User ID from a payload) plus injected services (like a Logger), you inject an IOrderFactory. The factory takes the runtime parameters, requests the static services from the container, and returns the constructed object.
