PublishAsync methoed PersistentConnection: Attempt to create a channel while being disconnected.

[zhujinhu21]

my easynetq is v0.50.12.407.

in the web(mvc) action I use PublishAsync method ，sometimes it happens error ，error message is
EasyNetQ.EasyNetQException: PersistentConnection: Attempt to create a channel while being disconnected.
在 EasyNetQ.PersistentConnection.CreateModel()
在 EasyNetQ.Producer.PersistentChannel.OpenChannel()
在 EasyNetQ.Producer.PersistentChannel.InvokeChannelActionInternal(Action1 channelAction, DateTime startTime) 在 EasyNetQ.Producer.PersistentChannel.InvokeChannelAction(Action1 channelAction)
在 EasyNetQ.Producer.ClientCommandDispatcherSingleton.<>c__DisplayClass5`1.b__2()

my code is
// POST api/values
public HttpResponseMessage Post([FromBody] TeslaOrder order)
{
using (var messageBus = RabbitHutch.CreateBus("host=localhost;username=zhujinhu;password=123456;publisherConfirms=true;timeout=60"))
{
//messageBus.Publish(order);
messageBus.PublishAsync(order).ContinueWith(task =>
{
// this only checks that the task finished
// IsCompleted will be true even for tasks in a faulted state
// we use if (task.IsCompleted && !task.IsFaulted) to check for success
if (task.IsCompleted && !task.IsFaulted)
{
Console.Out.WriteLine("{0} Completed", 11);
}
if (task.IsFaulted)
{
Console.Out.WriteLine("\n\n");
Console.Out.WriteLine(task.Exception);
Console.Out.WriteLine("\n\n");
}
});
}
return Request.CreateResponse(HttpStatusCode.Created);
}

when debug it go into task.IsFaulted。

Your bus instance is getting disposed before the message is published. Don't create an instance per call, create 1 instance per application domain.

Also, you're not returning the task from your controller action, so it executes outside the context of your controller action, that is not a good idea.
