The InvalidMessageContractException is thrown when custom attribute usage results in the generation of an invalid service description. For example, if a System.ServiceModel.MessageContractAttribute type has multiple parts with the same name, or a method has multiple parameters with the same name.

The following code example shows a contract and service that throws an InvalidMessageContractException that says operand appears more than once in the message.

[ServiceContract(Namespace = "http://contoso.com/IMath")]
public interface IMath
{
    [OperationContract]
    void Add(AddMessage a);
}

[MessageContract]
public class AddMessage 
{
    [MessageBodyMember(Name="operand")]
    public int a;

    [MessageBodyMember(Name = "operand")]
    public int b;
}
