title: WCF Multiple requests from same client
body: <p>i am building a WCF Service and i need clients to be able to acquire multiple results in the same time.
  For example 5 callings of void UploadPhoto(byte[] photo);
  and 1 string GetInfo()</p>
  
  <p>If I understand it correctly, than whenever I do a request for a service, I need to get a response for the first one before the second gets proceeded. Is that correct?</p>
  
  <p>Thanks</p>
