Reflection against protected fields not considered

[Rainer Bernhardt]

When sorting out private fields without the Serializable attribute, you might want to consider sorting out protected fields aswell

The check can be done with (field.IsPrivate || field.IsPublic == false)

if (!namespaceStr.StartsWith("UnityEngine", StringComparison.Ordinal) && (field.IsPrivate || field.IsPublic == false) && field.GetCustomAttributes(typeof(SerializeField), false).Length == 0)
{
    skipProperty = true;
 }

Great suggestion. I will begin work on the inclusion.

Thanks!
