title: Visual Studio custom warnings for non closed connections
body: <p>On our project I have noticed that there are many places where we forget to close some connections. Now the question is if it's possible to make visual studio show a warning if we don't close/dispose it?</p>
  
  <p>A correct example would be:</p>
  
  <pre><code>var app = new Application();
  
  try {
  //Some code
  } finally {
  app.Dispose();
  }
  </code></pre>
  
  <p>So my idea is if it's possible to make a warning that triggers if an Application/connection is created and an dispose is missing.</p>
