title: Does WPF have a set of default binding converters available?
body: <p>When creating WPF user controls I often find myself creating small converter classes when binding values.</p>
  
  <p>Often you need to do similar conversions, and it made me wonder whether I might be missing some existing available implementations.</p>
  
  <ul>
  <li>Does the .NET library contain any implementations of <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.ivalueconverter.aspx" rel="nofollow"><code>IValueConverter</code></a> or <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.imultivalueconverter.aspx" rel="nofollow"><code>IMultiValueConverter</code></a>?</li>
  <li>Has there been any attempt made to create a library of reusable value converters?</li>
  </ul>
