ProtoBuf WCF "No Model instance has been assigned" - wcf

Question

I am getting this error:
No Model instance has been assigned to the ProtoOperationBehavior
I just used the WCF template application in Visual Studio to see if I could get it running. How do I fix this error?
Code
public class Service1 : IService1
{
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
public CompositeType GetDataUsingDataContract(CompositeType composite)
{
if (composite == null)
{
throw new ArgumentNullException("composite");
}
if (composite.BoolValue)
{
composite.StringValue += "Suffix";
}
return composite;
}
}
[ServiceContract]
public interface IService1
{
[OperationContract]
[ProtoBehavior()]
string GetData(int value);
[OperationContract]
[ProtoBehavior()]
CompositeType GetDataUsingDataContract(CompositeType composite);
}
[DataContract]
[ProtoBuf.ProtoContract]
public class CompositeType
{
bool boolValue = true;
string stringValue = "Hello ";
[DataMember(Order = 1)]
[ProtoBuf.ProtoMember(1)]
public bool BoolValue
{
get { return boolValue; }
set { boolValue = value; }
}
[DataMember(Order = 2)]
[ProtoBuf.ProtoMember(2)]
public string StringValue
{
get { return stringValue; }
set { stringValue = value; }
}
}
app.config:

I tried using nuget. That did not work.
I would love to hear more about what problems you had there
I then tried to use the google code version (Core, net30 assembly), same error.
The "core only" library does not include the meta-programming layer - it is designed for use with pre-generated serialization assemblies. As such, there is no default model - one must always be provided.
The simplest "fix" here is simply to use the "full" build of the library; this has the meta-programming model as a default model.
