Desired functionality.

It should build

Mention any other details that might be useful.

the build pass when aot is disabled

[jotatoledo]

Shouldnt you inject that through a InjectionToken?

[hansl]

Hi @benbenw,

You cannot use a pure type to inject, e.g. an enum or an interface. You will need to use an InjectionToken, as @jotatoledo pointed out. Please follow Angular's documentation for help on how to use tokens.

Please note this is not a problem with the Angular CLI. This error (and further discussions and support) should be moved to github.com/angular/angular.

Closing this as Working As Intended.

[benbenw]

Sorry for the noise.

But it's misleading as it compiles without aot
