RabbitMQ C# connection trouble when using a username and password

It seems that I have found a solution to my own problem.
The following code works:

ConnectionFactory factory = new ConnectionFactory();
factory.UserName = "user";
factory.Password = "password";
factory.VirtualHost = "https://stackoverflow.com/";
factory.Protocol = Protocols.FromEnvironment();
factory.HostName = "192.168.0.12";
factory.Port = AmqpTcpEndpoint.UseDefaultPort;
IConnection conn = factory.CreateConnection();

Thanks for listening and perhaps this at least could be useful to someone else. 🙂
