    I want to known which one (s) would be the best solution in this scenario.

    1) Invoke the Service 1 that invoke business rules BLL, which will then access the DAL layer to perform CRUD operations.

    2) Shortly thereafter, the service 2 will be invoked , which will also make access to BLL and then access the DAL for CRUD.

    If an exception occurs in the execution of the operation of the Service 2 for example.

    Can I  implement so that everything that was done before will be undone, including operations of the service 1 ?

    Any sugestions ?


    thank you

    WCF Transactions

    Here is an example http://www.codeproject.com/Articles/38793/6-Steps-to-Enable-Transactions-in-WCF

    //1. Add TransactionFlow attribute to Service operations

[ServiceContract]
public interface IService1
{
[OperationContract]
[TransactionFlow(TransactionFlowOption.Allowed)]
void UpdateData();
}

//2. Add TransactionScopeRequired attribute to Service operation implementation
[OperationBehavior(TransactionScopeRequired = true)]
public void UpdateData()
{
//
}


//3.Enable transactionFlow for bindings in config
<bindings>
<wsHttpBinding>
<binding name="TransactionalBind" transactionFlow="true"/>
</wsHttpBinding>
</bindings>

//4. Attach binding to the end point
<endpoint address="" binding="wsHttpBinding" 
	bindingConfiguration="TransactionalBind" contract="WcfService1.IService1">

//5. Call the both services under Transaction scope
using (TransactionScope ts = new TransactionScope(TransactionScopeOption.RequiresNew))
{
try
{
ServiceReference1.Service1Client obj = new ServiceReference1.Service1Client();
obj.UpdateData();
ServiceReference2.Service1Client obj1 = new ServiceReference2.Service1Client();
obj1.UpdateData();
ts.Complete();
}
catch (Exception ex)
{
ts.Dispose();
}
}
