captive dependency

A long-lived object holding on to a short-lived one, so it outlives its time.

A captive dependency occurs when a longer-lived service (a singleton) depends on a shorter-lived one (scoped or transient), extending that dependency's lifetime; scope validation reports it.

Examples

  • A singleton cache that takes a scoped DbContext in its constructor keeps that one context for the life of the app.
