BusinessLogicModule - How to debug in VS??

I have followed the instructions listed in this https://msdn.microsoft.com/en-us/library/ms365150.aspx MSDN article but cannot get it working.  Can anyone shed some light on how to debug?  I have insalled VS 2015 on the subscriber and have the DLL dropped into the C:\Program Files\Microsoft SQL Server\120\COM folder.  I have my code listed below

    public class ReplicationBusinessLogicModule : BusinessLogicModule
    {
        private string _PublisherName;
        private string _SubscriberName;
        private string _ArticleName;
        private string _ReplicationTime;

        public ReplicationBusinessLogicModule()
        {
            var sb = new StringBuilder();
            sb.AppendLine("-------------------------------------");
            sb.AppendLine("In ReplicationBusinessLogicModule: " + DateTime.Now);
            sb.AppendLine("-------------------------------------");
            sb.AppendLine();
            System.IO.File.AppendAllText(@"C:\Temp\ReplicationBusinessLogicModule.txt", sb.ToString());
        }

        public override void Initialize(string publisher, string subscriber, string distributor, string publisherDB, string subscriberDB, string articleName)
        {
            _PublisherName = publisher;
            _SubscriberName = subscriber;
            _ArticleName = articleName;
            _ReplicationTime = DateTime.UtcNow.ToString("yyyy-MM-dd HH:mm:ss.fffffff", CultureInfo.InvariantCulture);

            var sb = new StringBuilder();
            sb.AppendLine("-------------------------------------");
            sb.AppendLine("In Initialize: " + DateTime.Now);
            sb.AppendLine("ArticleName: " + _ArticleName);
            sb.AppendLine("-------------------------------------");
            sb.AppendLine();
            System.IO.File.AppendAllText(@"C:\Temp\ReplicationBusinessLogicModule.txt", sb.ToString());

        }
