Knowing when you are in an injection context will allow you to use the [`inject`](api/core/inject) function to inject instances.
NOTE: For basic examples of using `inject()` in class constructors and field initializers, see the [overview guide](guide/di/overview#where-can-inject-be-used).

## Run within an injection context
When you want to run a given function in an injection context without already being in one, you can do so with `runInInjectionContext`.
This requires access to a given injector, like the `EnvironmentInjector`, for example:
<docs-code header="src/app/heroes/hero.service.ts" language="typescript"
highlight="[9]">
```ts {highlight: [9], header"hero.service.ts"}
@Injectable({

})
export class HeroService {
private environmentInjector = inject(EnvironmentInjector);

Note that `inject` will return an instance only if the injector can resolve the required token.
