Async Reponse

[ghost]

I have some problem in usage of .net sdk's.
TransloaditResponse responseFirst = null;
ITransloadit transloadit = new Transloadit.Transloadit();
IAssemblyBuilder assembly = new AssemblyBuilder();
String transloadPost = String.Empty;
for (int i = 0; i < Request.Files.Count; i++ )
{
assembly.AddFile(Request.Files[i].FileName);

            }

assembly.SetTemplateID(transloadit.Config.DefaultTemplateID);
responseFirst = transloadit.InvokeAssembly(assembly);

I got a sync response with responseFirst.Data["ok"] = ASSEMBLY_EXECUTING.
But I need async response with responseFirst.Data["ok"] = ASSEMBLY_COMPLETED.
I want to wait till process is completed like "PHP integration". I do not want to use notify_url parameter.
But I did not find that how I can use .Net sdk to get asyc response or wait while assembly is completed.
