If anyone is trying to create the KeyEventArgs for use in a unit test you'll find that Keyboard.PrimaryDevice.ActiveSource is null.. and throws an exception when you try to use it.

Mocking a PresentationSource is a workable solution (requires sta):

[Test]
[RequiresSTA]
public void test_something()
{
  new KeyEventArgs(
    Keyboard.PrimaryDevice,
    new Mock().Object,
    0,
    Key.Back);
}
