WCF transactions -


i imagine following wcf service usage: (of cash acceptor)

service consumer 1                           service consumer 2 cashacceptorservice.begintransaction();     cashacceptorservice.stopdevice();                                             //this should throw exception: device locked / used in transaction                                      cashacceptorservice.acceptmoney();            cashacceptorservice.endtransaction();

service consumer 1 , 2 use same wcf single instance. wonder if functionality implemented. wcf transactions offer this?

how see done?

if following true:

  • the service interacting transactional object (eg database)
  • the service has transaction flow enabled

then wcf indeed offer this.

the client can use transactionscope class. transactions initiated on client flow through service automatically.

using(transactionscope transactionscope = new transactionscope()) {      // stuff service here      cashacceptorservice.acceptmoney();      //      //      transactionscope.complete(); }

handling transactions in wcf tends entire chapter of book, should enough information on right track.
