c# - ConfigureAwait(true) not returning on the context it was awaited on -

-

sample : 

 static void main(string[] args)  {      int counter = 0;      var t = new system.timers.timer();      t.interval = 3000;      t.elapsed += async (sender, e) =>        {         debug.writeline("before await - thread : {0} , counter : {1}", thread.currentthread.managedthreadid, counter);         await task.delay(1000).configureawait(true);         debug.writeline("ater await thread : {0}, counter : {1} ", thread.currentthread.managedthreadid, counter);           counter++;          if (counter == 2)          {             debug.writeline("stop");             t.stop();          }      };       t.start();       console.readkey();  }

this outputs :

 before await - thread : 4 , counter : 0   ater await thread : 4, counter : 0    before await - thread : 5 , counter : 1   ater await thread : 4, counter : 1     stop

why didn't return on thread await called on. first time timer runs on thread 5 , suppose capture context when async operation ends, , can see returns on thread 4.

there isn't synchronization context in console app.

if run code in winforms , you'd see work expected..
