Hi i use wshttpbinding in my service Config and message security. my app works fine but after 10 or 20 min when client call any method of service, an exception throw cuz my security token will be expired, and connection cant be work.

one solution is re_create connection to make new token (but i cant use this cuz my service contain datacontext and if i re_create service, datacontext will be new)

other solution is change security type from message to transport (i try this solution but nothing change cuz other exception throw)
