Trigger an action to start after X milliseconds

you can try :

await Task.Delay(2000);

Just like you said this can be accomplished in a very clean way using Tasks and async programming.

You will want to read about it: http://msdn.microsoft.com/en-us/library/hh191443.aspx

Here's an example:

public async Task DelayActionAsync(int delay, Action action) 
{
    await Task.Delay(delay);

    action();
}
