In .Net 2.0 you can use the System.Media.SoundPlayer class instead:

.

SoundPlayer sound = new SoundPlayer(@"C:\Windows\Media\tada.wav");

.

sound.Load(); // can also be called asychronously i.e. LoadAsync()

.

sound.Play(); // default is to play asyncronously

.

Or you can play a system specific sound:

.

My.Computer.Audio.PlaySystemSound(Media.SystemSounds.Asterisk)
