ServiceBus Serialization Scenarios

ServiceBus Serialization Scenarios.
Use BrokeredMessage with explicit json to understand whats going on.
E.g. for using in Azure functions

class MyData
{
 public string name {get;set;}
}

// Sender
[FunctionName("Send")]
public static void Send(..., [ServiceBus("%Topic%")] out BrokeredMessage brokeredMessage, ...)
{
 ...
 MyData myData = new MyData();
 string bodyJson = JsonConvert.SerializeObject(myData);
 brokeredMessage = new BrokeredMessage(bodyJson);
 brokeredMessage.Label = "My routing info";
 ...
}

// Receiver
[FunctionName("Receive")]
public static void Receive([ServiceBusTrigger("%Topic%", "%Subscription%")] BrokeredMessage brokeredMessage, ...)
{
 ...
 string bodyJson = brokeredMessage.GetBody<string>();
 MyData myData = JsonConvert.DeserializeObject<MyData>(bodyJson);
 ...
}

If you want to send a test message using Service Bus Explorer in the send message dialog just paste the json e.g. {"name":"Andreas"} into Message -> Message Text and then set Sender -> Body Type to String (i.e. not Stream). Set the Label as well if you want to route the message.
