Version to support the .Net 2.0 framework.
This version uses a version of the Mono library for JSON and RestSharp.
Here is an example to call using async in C# .Net 2.0.
If you do not neet async call one of the other methods directly.
Thread t = new Thread(submitJob);
t.Start();
private void submitJob()
{
Client smClient = new Client("API_KEY");
smClient.trackasync("METRIC_NAME", 1);
}
