hello,

I wanted to know what is the use the MessageParameterAttribute in wcf.

In my function:

[OperationContract]
public float GetAirfare(
[MessageParameter(Name=”fromCity”)] string originCity,
[MessageParameter(Name=”toCity”)] string destinationCity);

I dont use fromCity or toCity anywhere in the implementation or even while using a service. Then whats the point in giving it a name?
