c# - Simple HttpClient test failing on Mono -

when executing simple little test on mono (3.2.1) on mac os x never prints response console instead says shutting down finalizer thread timed out.
there wrong code or mono misbehaving?

using system; using system.net.http;  namespace vendtest {   class mainclass   {         public static void main(string[] args)         {             client client = new client();             client.httpclientcall();         }     }      public class client     {         httpclient client;          public client()         {             client = new httpclient();         }          public async void httpclientcall()         {             httpclient httpclient = new httpclient();             httpresponsemessage response = await httpclient.getasync("http://vendhq.com");             string responseasstring = await response.content.readasstringasync();             console.writeline(responseasstring);         }     } } 

you should never use async void methods , 1 reason why. main() end before httpclientcall() completes. , since exiting main() terminates whole application, nothing printed.

what should change method async task , wait() in main(). (mixing await , wait() can lead deadlocks, it's right solution for console applications.)

class mainclass {     public static void main()     {         new client().httpclientcallasync().wait();     } }  public class client {     httpclient client = new httpclient();      public async task httpclientcallasync()     {         httpclient httpclient = new httpclient();         httpresponsemessage response = await httpclient.getasync("http://vendhq.com");         string responseasstring = await response.content.readasstringasync();         console.writeline(responseasstring);     } }
