  <p>Here i am using <a href="https://www.nuget.org/packages/Tulpep.NotificationWindow/" rel="nofollow noreferrer">Tulpep notification</a> for create desktop notification. I have one start button in my form. When start button clicked, timer start to pop desktop notification. But it is shows notification only when i not comment on  <code>MessageBox.Show("");</code>. and if i remove or comment <code>MessageBox.Show("");</code> it is not showing notification. I debug in both case, there is no error or exception in both case.</p>
  
  <p>Is any one have idea why is this happening?</p>
  
  <p>I am using <code>.net framework 4.5.2,visual studio 2015, windows 8</code>.</p>
