Getting ready
For this sample, we will be using the editable OData API exposed by odata.org. Just a note, at the time of writing the book this service was provided for testing OData edit features with some restrictions.
You can browse OData using http://services.odata.org/(S(bltvbobia1rthiavqczdcr1u))/OData/OData.svc/. We will be using this link to consume the data in this recipe. For simplicity, we shall only update the categories.

datasvcutil /uri:http://services.odata.org/(S(bltvbobia1rthiavqczdcr1u))/OData/OData.svc/ /out:.\EditODataModel...
