Use of wcf transaction with example

A WCF Transaction allow us to make operations that consumers can use inside transactions. We can call a wcf service operation inside a transaction scope (for example) and ensure that our operation will be atomic. It's really helpful to ensure integrity in our operations.

For example, suppose that we have two wcf operations:

  • debit(double mont,string account);
  • deposit(double mont,string

If I've implemented wcf transactions I can build up a transfer operation mixing the two operations in a transaction and I'll be sure that there will not be any inconsistency. If any of service calls fail , the entire transaction will rollback.

try
{
  using(TransactionScope scope = new TransactionScope())
  {
     IserviceClient client = new IserviceClient();
     client.debit(499,"acdf5-sdsd-4546-223-2");
     client.deposit(499,"45651-as4d-ghhd-222-1");

     scope.Complete();
  }
}
catch
{
   Debug.WriteLine("Some error occurred...");      
}

It can be helpful. http://www.codeproject.com/Articles/183708/WCF-Transactions-Brief-Introduction

EDIT: You should use transactions when the service operation changes any state (a database insert,update or delete, any file modification) although transactions are not useful when you do a simple read operation for example.
