Question

I’m using the WCF Project on Codeplex (also known as WebAPI via Nuget). My simple service produces XML beautifully, but returns JSON where every property is named “item”.

[OperationContract]
[WebGet(UriTemplate = "all")]
public IQueryable<myobject> GetAllUsers() {
    return (from myobject u in MyDatabase.MyObjects
           select u).AsQueryable();
}

Here’s the generated JSON.

[
  {
    "item":null,
    "item":641412011,
    "item":null,
    "item":"en_US",
    "item":"-7",
    "item":true
  }
]

The return value is a public class POCO.

[Serializable]
public class MyObject {
    [DataMember(Name = "id")]
    public int ID { get; set; }

    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "first_name")]
    public string FirstName { get; set; }

    [DataMember(Name = "last_name")]
    public string LastName { get; set; }
}

Has anyone seen this?

Sorry. Some digging tipped me off that I was missing the [DataContract] attribute on my POCO class.

[Serializable]
[DataContract]
public class MyObject {
    [DataMember(Name = "id")]
    public int ID { get; set; }

    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "first_name")]
    public string FirstName { get; set; }

    [DataMember(Name = "last_name")]
    public string LastName { get; set; }
}
