ScenarioExisting WCF Service

TransactionFlow is mandatoryTransactionScope is required for “PlaceOrder” method

‘PlaceOrder’ method If message header “BeginNewPO” exists, create a key randomly and insert PO into PO tableOtherwise, Insert lineItem details in message to PODetails table

BizTalk Send Port emits a single documentPO master detailsMultiple PO LineItem details

Requirement

Need to split the single BizTalk documentCreate WCF message with header for PO master detailsCreate Multiple WCF messages, one for each Line item

Initiate a transactionAs part of the same transaction

Send WCF message with PO headerSend WCF messages for each Line Item

Solution

Create a Custom Binding Element in WCFWCF Message InterceptionSplit WCF Message into

Single message for Order headerMultiple messages , one for every Line Item in the orderSubmit the messages one by one

Create a Custom Binding in BizTalk Send Port Use WCF-Custom adapterConfigure binding

By themselves, WCF and BizTalk add significant value

Integrating them provides enhances the value

Leveraging ScenariosWS-* standards support of WCF in BizTalk

WCF extensibility scenarios are easy configurable in BizTalk
