azureservicebus - Async Monitoring Azure Service Bus With Worker Role -

i have worker role monitoring azure service bus can potentially receive thousands of messages @ peak times. realize can use cloud service create multiple instances of worker role (competing consumers), , scale way, each worker instance asynchronously handle multiple messages well.

so question in this; in client.onmessage handler, can call async function goes off on thread, , onmessage resumes reading next message? ideally, happen defined number of times.

for example:

 client.onmessage((receivedmessage) =>             {                 try                 {                    await processcurrentmessage(receivedmessage);                    // launch asynchronously x times                  }                 catch(exception ex)                 {                     receivedmessage.abandon();                    //handle error                 }             });     public async void processcurrentmessage(brokeredmessage receivedmessage)   {         // properties message , stuff   } 

what trying scale having each worker role handle x amount of messages @ time, leveraging cpu on cloud service, , enhance adding more cloud instances. if had 20 messages in queue , 10 consumers, 10 start (1 per competing consumer), 11th message wait until 1 finished, etc. seems kind of road block if each message took several minutes process.

appreciate advice or tips.
