Reset variable value after delay in WPF

I have code that executes and gets the return value of the execution. I set this value to the dependency property of my window because there are style triggers associated with it. When a variable is 0, it uses the default style when 1 is reddish and when 2 is greenish.

But I have to reset this style after some time in some practical way.

What is the easiest way to do this?

if (!Compiler.TryCompile(strText, Models[Model], EntryPoint.Text, out error))
{
    output.Items.Add("Error compiling:");
    output.Items.Add(error);
    CompilationStatus = 1; // dependency property bound on ui
}
else {
    output.Items.Add("Compilation successful!");
    CompilationStatus = 2; // dependency property bound on ui
}

// should execute this after 5 seconds 
CompilationStatus = 0;  // dependency property bound on ui

The project uses WPF and .Net 4. Thanks !!

Usually, a special extension method is used for this:

public static class DispatcherHelper
{
    public static void DelayInvoke(this Dispatcher dispatcher, TimeSpan ts, Action action)
    {
        DispatcherTimer delayTimer = new DispatcherTimer(DispatcherPriority.Send, dispatcher);
        delayTimer.Interval = ts;
        delayTimer.Tick += (s, e) =>
        {
            delayTimer.Stop();
            action();
        };
        delayTimer.Start();
    }
}

In your case, you can use it as follows:

Dispatcher.DelayInvoke(TimeSpan.FromSeconds(5), () => 
{
   CompilationStatus = 0; 
}

, WPF .Net 4, , :

new Task(delegate() {
  Thread.Sleep(5000);
  Dispatcher.Invoke((Action)delegate(){
     CompilationStatus = 0;
  });
}).Start();
