Since the CloudToScope dictionary now uses StringComparer.InvariantCultureIgnoreCase, converting environment.Name to lower case is unnecessary and could be removed for clarity.

Suggested change

	?? CloudToScope.GetValueOrDefault(environment.Name.ToLower(), null);
	?? CloudToScope.GetValueOrDefault(environment.Name, null);
