How to stop a delegate to be serialized in WCF?

Question

How to stop a delegate to be serialized in WCF.

 

My code is like below:

public delegate void ClientCallback(CommonContracts.IEventData a_ErrorData); 

 

 

 

I would like to do this because i am getting below error:

<Message>There was an error while trying to serialize parameter http://tempuri.org/:GetDriveResult. The InnerException message was 'Type 'System.DelegateSerializationHolder+DelegateEntry' with data contract name 'DelegateSerializationHolder.DelegateEntry:http://schemas.datacontract.org/2004/07/System' is not expected.

Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.'.

Please see InnerException for more details.

</Message>

 

Can any body help me here?
