Bien codé et commenté, merci bien :)

Comme j'ai passé un peu de temps à refaire l'exemple présent dans la classe pour une utilisation WPF, je la dispose ici pour ceux que ça intéresse :

using System;
using System.Threading;
using System.ComponentModel;
using System.Windows.Threading;

namespace IdleInput
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
private InputInfos.ClsAfIdleInfos IdleWatch = null;

private BackgroundWorker backgroundWorker1 = new BackgroundWorker();

#region "Thread pour Label"
private string mThreadText = string.Empty;

delegate void SetTextCallback(string text);
private void SetText(string sText)
{
if (richTextBox1.Dispatcher.CheckAccess())
{
// The calling thread owns the dispatcher, and hence the UI element
richTextBox1.AppendText(sText);
}
else
{
// Invokation required
SetTextCallback d = new SetTextCallback(SetText);
richTextBox1.Dispatcher.Invoke(d, new object[] { sText });
}
}
private void SetThreadText(string sText)
{
mThreadText = sText;
while (backgroundWorker1.IsBusy)
{
// Remplace Application.DoEvents();
Application.Current.Dispatcher.Invoke(
System.Windows.Threading.DispatcherPriority.Background,
new ThreadStart(delegate { })
);
}

backgroundWorker1.RunWorkerAsync();
}
#endregion

public Window1()
{
InitializeComponent();

//instanciation ClsAfIdleInfos
IdleWatch = new InputInfos.ClsAfIdleInfos(20000, InputInfos.ClsAfIdleInfos.WatchingFrenquencyConstants.Fast);

//events
IdleWatch.CameBack += new InputInfos.EventHandler(IdleWatch_CameBack);
IdleWatch.IdleExpired += new InputInfos.EventHandler(IdleWatch_IdleExpired);
IdleWatch.IdleTick += new InputInfos.IdleTickEventHandler(IdleWatch_IdleTick);

//backgroundWorker event
backgroundWorker1.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorker1_RunWorkerCompleted);
}

private void IdleWatch_CameBack(object sender, EventArgs e)
{
SetThreadText("Activité détectée");
}
private void IdleWatch_IdleTick(object sender, InputInfos.IdleTickEventArgs e)
{
SetThreadText(String.Format("Utilisateur sans activité depuis {0} seconde(s)", e.ElapsedTime));
}
private void IdleWatch_IdleExpired(object sender, EventArgs e)
{
MessageBox.Show(String.Format("Fin de l'observation : {0} ms sans activité.", IdleWatch.GetIdleTimeSpan()));
IdleWatch.Dispose();
}

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
this.SetText(mThreadText);
}
}
}
