title: .NET equivalent for GetLastInputInfo?
body: <p>Is there a .NET equivalent to the Windows <a href="http://msdn.microsoft.com/library/ms646302.aspx" rel="noreferrer"><code>GetLastInputInfo()</code></a> API?</p>
  
  <p>I know it's possible to P/Invoke the API but I'm looking for a method or technique that's already built into the .NET framework.</p>
