Small error in the sample code, the ThrowIfNull method takes 2 parameters. The first is the variable to check for null, the second is the name of the parameter that will end up in the exception if thrown.

So the correct call would be ArgumentNullException.ThrowIfNull(subscriber, nameof(subscriber));
