c# - Memory leak in MediaPlayer -

can please explain why following program runs out of memory?

class program {     private static void threadroutine()     {         system.windows.media.mediaplayer player = new system.windows.media.mediaplayer();     }      static void main(string[] args)     {         thread athread;         int iteration = 1;          while (true)         {             athread = new thread(threadroutine);             athread.start();             athread.join();              console.writeline("iteration: " + iteration++);         }     } } 

to fair, specific exception system.componentmodel.win32exception, "not enough storage available process command." exception happens on attempt create new mediaplayer.

mediaplayer not implement idisposable interface i'm not sure if there other cleanup necessary. didn't find in mediaplayer documentation.

my guess thread objects created aren't garbage collected in time.

as stating in comment are out of luck respect finding solution doesn't involve memory leak, i'm posting alternative answer though doesn't attempt answer original question.

if use threadpool instead, (a) runs faster , (b) not crash.

class program {     private static void threadroutine(object state)     {         var player = new mediaplayer();          var iteration = (int)state;         if (iteration % 1000 == 0)         {             console.writeline("executed: " + state);         }     }      static void main(string[] args)     {         (int = 0; < 10000000; i++)         {             if (i % 1000 == 0)             {                 console.writeline("queued: " + i);             }              threadpool.queueuserworkitem(threadroutine, i);         }     } }

on machine, have no problem creating 10 million thread-pool threads in few seconds.
