Question

I have following object, it works fine when I specify standart objects like int, string and not with custom object.

[DataContract(Namespace = "")]
public class StatusLog<TItem>
{
    /// <summary>
    /// Gets or sets the key.
    /// </summary>
    /// <value>
    /// The key.
    /// </value>
    [DataMember]
    public Guid Id { get; set; }

    /// <summary>
    /// Gets or sets the action status.
    /// </summary>
    /// <value>
    /// The action status.
    /// </value>
    [DataMember]
    public ActionStatus ActionStatus { get; set; }

    /// <summary>
    /// Gets or sets the object.
    /// </summary>
    /// <value>
    /// The object.
    /// </value>
    [DataMember]
    public TItem Object { get; set; }

    /// <summary>
    /// Gets or sets the message.
    /// </summary>
    /// <value>
    /// The message.
    /// </value>
    [DataMember]
    public string Message { get; set; }
}

This works:
return new StatusLog { Id = Guid.NewGuid(), ActionStatus = ActionStatus.Deleted, Object = Convert.ToInt32(id), Message = “Node deleted successfully” };

This does not work:
new StatusLog {Id = Guid.NewGuid(), ActionStatus = ActionStatus.Created, Object = MyCustomObject};

Have a look at KnownType Attribute.
