.net - How to do wcf routing service using xpath? -

-

i have wcf project needs routing stuff. 1 scenario there is, service versioning. example if there change or new service needs implemented new client on wcf service breaking, create different service endpoint consumed new client. bu thing old client should still able communicate older version of service(that's how service versioning should work right?). so, decided use wcf routing service using xpath method.

two things can xpath method, either check version on data contract using content filtering or looking @ header. want both sake of bench marking. understand how xpath work don't know how implement it.

any tutorials or examples appreciated. found few examples on web they're not giving full config.

best regards,
