        NormalWaitDialog/*your wait form*/ _frmWaitDialog = null;


        //Btn Load Click Event
        _frmWaitDialog = new NormalWaitDialog();
        _frmWaitDialog.Shown += async (s, ee) =>
        {
            await Task.Run(() =>
           {
               // DO YOUR STUFF HERE 

               //Made long running loop to imitate lengthy process
               int x = 0;
               for (int i = 0; i < int.MaxValue; i++)
               {
                   x += i;
               }

           }).ConfigureAwait(true);
            _frmWaitDialog.Close();
        };
        _frmWaitDialog.ShowDialog(this);
