How should I validate parameters passed into my WCF service?

Normally you check incoming parameters in your public methods using if-then-throw pattern or Code Contracts.
My question is, how should I validate parameters passed in my WCF service? For example, I've got the following contract:

[OperationContract]
Stock GetStock(string symbol);

I want to ensure that symbolparameter is not null or empty string. Should I use the same if-then-throw pattern or Code Contracts precondition on the service-side? Should I add a FaultContract attribute to the GetStock method and return a fault to the client? What's the best parameters validation technique for WCF service?

Enterprise Library Validation Application Block has an adaptor for integration with WCF designed for exactly this.

This CodeProject Introduction is a little old but gives a bit more background than the MSDN links.
