    copied!<p>I'm writing code to consume the Bing Geocode service (Bing Maps), and I am successfully able to pull JSON data via wcf, unfortunately I seem to be unable to map a piece of the data returned.</p> <p>I created all the appropriate DataContracts as needed and populated them with the required members, but I when I start getting into the children I get the following error:</p> <p>Element ':item' contains data from a type that maps to the name 'http://schemas.microsoft.com/search/local/ws/rest/v1:Location'. The deserializer has no knowledge of any type that maps to this name. Consider using a DataContractResolver or add the type corresponding to 'Location' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer.</p> <p>So I commented out the "children" objects, and was basically able to discern that it was blowing up when it tries to read the 'Location' part of the JSON object</p> <p>in my code below, it concerns the part here:</p> <pre><code> "__type":"Location:http:\/\/schemas.microsoft.com\/search\/local\/ws\/rest\/v1", </code></pre> <p>for what its worth, the url is bad, but I don't care. I don't want to use that type (which apparently maps back to a schema at Microsoft's website). Is there a way to tell WCF to ignore that link? Its not like <em>I</em> can. </p> <p>What Bing returns</p> <pre><code>{ "authenticationResultCode":"ValidCredentials", "brandLogoUri":"http:\/\/dev.virtualearth.net\/Branding\/logo_powered_by.png", "copyright":"Copyright © 2010 Microsoft and its suppliers.
