Answer 1

I used Olivier Jacot-Descombes's solution, it's very simple and working well. thanks. update: it even works well without using a different threads/background worker.

I use it with backgroudworker, mouse cursor looks great when it's busy working and return to normal when the work is done.

public void pressButtonToDoSomeLongTimeWork()
{    
    Mouse.OverrideCursor = Cursors.Wait;
    // before the long time work, change mouse cursor to wait cursor

    worker.DoWork += doWorkLongTimeAsync;
    worker.RunWorkerCompleted += worker_RunWorkerCompleted;
    worker.RunWorkerAsync();  //start doing some long long time work but GUI can update
}

private void worker_RunWorkerCompleted(object sender,     
                                       RunWorkerCompletedEventArgs e)
{
    //long time work is done();
    updateGuiToShowTheLongTimeWorkResult();
    Mouse.OverrideCursor = null;  //return mouse cursor to normal
}
