BindingList equivalent in Silverlight? Want to observe changes in collection elements
<p>I was looking around for something like <a href="http://msdn.microsoft.com/en-us/library/ms668604.aspx" rel="nofollow"><code>ObservableCollection&lt;T&gt;</code></a> that would also raise an event whenever the properties of item in the collection change.  I came across <a href="http://msdn.microsoft.com/en-us/library/ms132679.aspx" rel="nofollow"><code>BindingList&lt;T&gt;</code></a>, but was disappointed to learn that it's not available in Silverlight.</p>

<p>I'm aware that I could build this fairly easily by subclassing <a href="http://msdn.microsoft.com/en-us/library/ms668604.aspx" rel="nofollow"><code>ObservableCollection&lt;T&gt;</code></a> and subscribing to the PropertyChanged events of items as they are added (and unsubscribing as they are removed, of course).  Before I do that, though, I want to make sure there isn't something I can use out of the box.</p>
