Analyzer

Diagnostic ID: CA1860

Describe the improvement

An interface such as IReadOnlyList<> inherits its Count property from IReadOnlyCollection<>.

I believe it makes sense for the CA1860 diagnostic to apply to these types as well?

Describe suggestions on how to achieve the rule

Update the HasEligible*Property methods to also inspect AllInterfaces / BaseTypes, similar to the UseCountProperly analyzer.

Additional context

namespace Test;

public class Class1 {
	public void Foo() {
		IReadOnlyList<int> list = [];
		IReadOnlyCollection<int> collection = list;

		if( list.Any() || collection.Any() ) {
			return;
		}
	}
}
