c# - Check if component is resolved in outermost LifetimeScope -

-

i reworking existing codebase make better use of autofac container. situation i'm having lot of things used resolve components straight container in classic servicelocator anti-pattern. i'm in process of introducing proper unit-of-work schemes using lifetimescope.

the issue i'm facing component must resolved child lifetimescope implementing idisposable , must disposed. if they're resolved in root scope never happen.

is there way prevent components being resolved in root scope? crashing runtime ok this, since i'm going through these cases 1 one , introducing scopes needed. way can think of create little dummy component gets resolved once root lifetime scope , resolving in .instanceperlifetimescope(), storing statically somewhere. when later component resolved i'll 1 of dummy components , see if it's same instance 1 lifes in root scope. it's bit clunky though, , there better way?

you try using 'per matching lifetime scope' registration:

containerbuilder.registertype<foo>()                 .as<ifoo>()                 .instancepermatchinglifetimescope("scope");

this way ifoo can resolved when @ least 1 ancestor lifetime scope tagged lifetime scope , tag equals "scope". root lifetime scope not tagged, when try resolve ifoo it, autofac throw exception.

see the autofac wiki more information.
