I experienced the same error message. I managed to fix it:

In my case the error was that I missed the [datacontract] and [datamember] attributes in the parent class of my returned class. The error message was misleading.

[OperationContract]
List GetData();

[DataContract]
public class MyClass : MyParentClass
{       
    [DataMember]
    public string SomeString { get; set; }      
}

// Missing DataContract
public class MyParentClass
{
    // Missing DataMember
    public int SomeNumber { get; set; }

}
