title: WCF Data Services 5.2 MaxProtocolVersion
body: <p>When I set <code>MaxProtocolVersion</code> to V3 my service no longer accepts requests stating <code>MaxDataServiceVersion: 2.0</code>. Response from the service is:</p>
  
  <pre><code>HTTP/1.1 400 Bad Request
  Cache-Control: private
  Content-Length: 158
  Content-Type: application/json;odata=verbose;charset=utf-8
  Server: Microsoft-IIS/7.5
  X-AspNet-Version: 4.0.30319
  X-Content-Type-Options: nosniff
  DataServiceVersion: 1.0;

  {"error":{"code":"","message":{"lang":"nb-NO","value":"The MaxDataServiceVersion '2.0' enter code hereis too low for the response. The lowest supported version is '3.0'."}}}
  </code></pre>
  
  <p>How can a service configured as version 3 handle requests from clients compliant with version 2?</p>
