title: Azure ServiceBus returns null on Client.Receive()
body: <p>I have a problem with receiving messages from a queue i have set up in azure.
  I have done this successfully using the same code before but now i just get null when i try to fetch messages.
  When i view the queue in azure management console i clearly see that the queue contains 5 messages.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>ServiceBus SB = new ServiceBus();
  Microsoft.ServiceBus.Messaging.BrokeredMessage message;
  while (true)
  {
      message = SB.ReceiveMessage("orders");
      if (message == null)
      {
          break;
      }
      Procurement.Order order = message.GetBody&lt;Procurement.Order&gt;();
      order.id = Guid.NewGuid().ToString();
      order.remindercount = 0;
  
      using (DbManager db = new DbManager())
      {
          if (db.SetSpCommand("CreateOrderHead",
              db.Parameter("@companyId", order.companyId),
              db.Parameter("@orderId", order.orderId),
              db.Parameter("@suppliercode", order.suppliercode),
              db.Parameter("@supplierorderId", order.supplierorderId),
              db.Parameter("@orderdate", order.orderdate),
              db.Parameter("@desireddate", order.desireddate),
              db.Parameter("@ordertext", order.ordertext),
              db.Parameter("@name", order.name),
              db.Parameter("@street", order.street),
              db.Parameter("@zip", order.zip),
              db.Parameter("@city", order.city),
              db.Parameter("@country", order.country),
              db.Parameter("@countrycode", order.countrycode),
              db.Parameter("@deliveryterms", order.deliveryterms),
              db.Parameter("@reference", order.reference),
              db.Parameter("@deliveryinstruction", order.deliveryinstruction),
              db.Parameter("@id", order.id),
              db.Parameter("@partycode", order.partyCode)
              ).ExecuteNonQuery() == 1)
          {
              message.Complete();
              message = null;
          }
  
          db.SetSpCommand("DeleteOrderRows",
              db.Parameter("@orderid", order.orderId),
              db.Parameter("@companyId", order.companyId)
              ).ExecuteNonQuery();
  
          foreach (Procurement.Orderrow r in order.Orderrows)
          {
              db.SetSpCommand("CreateOrderRow",
              db.Parameter("@companyId", r.companyId),
              db.Parameter("@orderId", r.orderId),

          }
      }
  }
  Thread.Sleep(new TimeSpan(0, 1, 0));

  <p>And this is the ServiceBus-class:</p>

  <p>I think this should be pretty straight forward but i cant find out what im doing wrong.
  Its probably something small that im missing...</p>
