Alternative to TypeDescriptor in Silverlight 3?
<p>Am using this code in WPF to check for properties.</p>

<pre><code>if (TypeDescriptor.GetProperties(this)[propertyName] == null)
{
      //some code here...
}
</code></pre>

<p>I want to use the same logic in Silverlight 3, but there is no TypeDescriptor. Anyone knows an alternate way to do it in Silverlight.</p>
