[zsolt-kolbay-sonarsource]

Description

S1144 does not highlight unused private getters or setters when they are inside a public property.

Repro steps

public class PropertyAccess
{
    public int PrivateGetter { private get; set; } // FN - unused private getter
    public int PrivateSetter { get; private set; } // FN - unused private setter

    public int ExpressionBodiedPropertyWithPrivateGetter { private get => 1; set => _ = value; } // FN - unused private getter
    public int ExpressionBodiedPropertyWithPrivateSetter { get => 1; private set => _ = value; } // FN - unused private setter
}

Expected behavior

An issue should be raised for the unused getter or setter.

Actual behavior

No issue is raised.

Known workarounds

None.
