title: What does Microsoft.Practices.ServiceLocation.ServiceLocator do?
body: <p>I know this sounds lame, but MSDN seems to have a bunch of empty information on it. Like this link <a href="http://msdn.microsoft.com/en-us/library/microsoft.practices.servicelocation.servicelocator%28v=pandp.51%29.aspx" rel="nofollow">ServiceLocator</a>. I just rolled onto a project with Unity and Prism. I have found it in some code where a WPF UserControl is passed in like this</p>
  
  <pre><code>var alert = ServiceLocator.Current.GetInstance&lt;AlertControl&gt;();
  </code></pre>
  
  <p>Is this like Unity's resolve?</p>
