NullInjectorError: No provider for Store!

[sandeep206]

I was following the Reactive workshop steps. After completing the 1 step, while running I got the error No provider for Store in my component.
Later realized the store StateModule needs to be injected in the app module.
This might help someone in the future.

I had a weird similar issue where CoreDataModule is being imported by both AppModule and ProjectsModule causing an issue with StoreModule.forRoot() being invoked twice.
I removed the duplicate import from ProjectsModule and that seemed to work for me.
