Producer messages using Apache.NMS Console app and Windows Forms

Question

I am trying to produce messages to and consume messages from ActiveMQ Artemis queues for the first time. I am able to connect and produce messages via Apache.NMS.ActiveMQ as well as Apache.NMS.AMQP when I use the code in a C# console application. However, when I put that same code in a C# Windows forms application the CreateSession method call runs forever.

IConnectionFactory factory = new ConnectionFactory(brokerUri);
using (IConnection connection = factory.CreateConnection(username, password))
{
    using (ISession session = connection.CreateSession(AcknowledgementMode.AutoAcknowledge))
    {
        IDestination destination = session.GetQueue(queueName);
        IMessageProducer producer = session.CreateProducer(destination);
        IMessage textMessage = session.CreateTextMessage(text);
        producer.Send(textMessage);
    }
}

My broker is using SSL, and I use the Apache.NMS.ActiveMQ library with the brokerUri="ssl://mybroker:443" and I use Apache.NMS.AMQP with the brokerUri="amqps://mybroker:443". Again, each of these work fine when run in a Console app, but not a Windows Forms app.

For the tl;dr crowd:

We've encountered this issue in AMQ6 and AMQ7. The workaround mentioned in the jira issues and the comments above is to wrap any AMQ connection code in a Task.Run, like so:

System.Threading.Tasks.Task.Run(() =>{
    connnection.Start();
});
