title: What is the difference between an App and Application in c#.net?
body: <p>Is there any difference between <code>App</code> and <code>Application</code> in c#?</p>
  
  <p>I am trying to use <code>App.current.Resources</code> in control library which is loaded in main <code>WPF</code> application. But it is not possible in a straight way, but at the same time it is allowing me to use <code>Application.current.Resources</code> </p>
  
  <p>Could anyone help me to understand the basic differences between these two. 
  Is there any flaw on using <code>Application.Current.Resources</code> instead of <code>App.current.Resources</code>?</p>
