WCF Adapter Core Features

Seven traditional BizTalk adaptersWCF-BasicHttpWCF-WsHttpWCF-NetTcpWCF-NetMsmqWCF-NetNamedPipeWCF-CustomWCF-CustomIsolated

UI Ensures ease of use and minimizes potential for mis-configuration

WCF as Adapter for BizTalk

The Flow

Complementary Support

WCFplatform for building services on WindowsSupport for Standard communication protocols for services on Windows

BizTalkStandards based Integration and BPM Server for WindowsInfrastructure for orchestrating and extending WCF services

Use Cases

Exposing BizTalk orchestration as a WCF serviceConsuming a WCF service from BizTalk orchestration Transactional Receive and SendUsing Headers

WS-* headers for routing and message processing Custom headers

Using BizTalk as SOAP intermediary

Use Cases

Using custom binding elements Using custom bindings Using BizTalk dynamic send ports Consuming a WCF Service originating from WCF-LOB Adapter (SAP, Siebel, Oracle DB, and Tibco RV)

Wizards

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
