shared service at module level

[chesminsky]

Hi.
I m trying to implement dynamic loading using your technique.
I got some problem.
If my dynamic module has providers

@NgModule({
	providers: [
		SampleService
	],
//....
})

and this service is injected in component i get
NullInjectorError: No provider for SampleService!
if i declare it as

@Component({
	providers: [
		SampleService
	],
})

everything seems ok, but service get destroyed with component

I need help...
How can i make shared service at module level ?
PS my angular version is 5
