How to use Perception simulation in Unity

Hi,

I have Unity 2017.1.0f3 version. I managed to import the "PerceptionSimulation" dll's into my unity project.
I have created a TestRunner->Editmode test and wrote the following:

Task.Run(async () =>
{
System.Uri a = new System.Uri("http://169.254.48.38/");
try
{
//Thread.Sleep(5000);
System.Console.WriteLine("inside try");

RestSimulationStreamSink sink = await RestSimulationStreamSink.Create(
// use the IP address for your device/emulator
a,
// no credentials are needed for the emulator
new System.Net.NetworkCredential("", ""),
// normal priorty
true
// cancel token
);
System.Console.WriteLine("simulaiton manager object created");
IPerceptionSimulationManager manager = PerceptionSimulationManager.CreatePerceptionSimulationManager(sink);


But, the sink object is not getting initialised. The second print state is not printed. Only System.Console.WriteLine("inside try"); is printed.

How do I proceed with this?

Thanks!
