title: How do I implement IDataServiceMetadataProvider and tell my Data Service to use that custom provider?
body: <p>There's no obvious entry point for implementing a custom provider for an ADO.NET Data Service using <code>IDataServiceMetadataProvider</code>, and then telling a Data Service to use that provider. Has anyone had any luck in this area? I've tried implementing this interface on my Data Source class, but none of my breakpoints are hit. There is also no (obvious) way to set the provider from the Data Service's <code>DataServiceConfiguration</code> parameter passed in to the <code>InitializeService</code> function.</p>
  
  <p>Any help would be appreciated. Thanks!</p>
