Declaring a Form before a SpeechRecognitionEngine prevents speech recognition

If I declare a new Form before I call SpeechRecognitionEngine.SetInputToDefaultAudioDevice();, then the SpeechRecognitionEngine wont recognize any speech. Why is this.

Here is the code

namespace Test2
{
    class Program
    {
        static void Main()
        {
        Form form1 = new Form();

        SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine();
        recognizer.SetInputToDefaultAudioDevice();
        recognizer.LoadGrammar(new DictationGrammar() );
        recognizer.SpeechDetected += Program.SpeechDetectedEvent;
        recognizer.RecognizeAsync();

        while(true){}
        }

static void SpeechDetectedEvent(Object sender, SpeechDetectedEventArgs e){
Console.WriteLine("Detected Speech");
}

}
}

You'll notice that if you move form1 = new Form(); ahead of SetInputToDefaultAudioDevice, then the recognizer will detect speech.

My guess/hypothesis is that it has something to do with message loops and threading but my knowledge is to limited to judge.
