1 Birds of the Same Feather BizTalk and WCF K.Meena Director SymIndia Training & Consultancy Pvt Ltd Session Code:

2 Agenda Overview WCF BizTalk WCF-BizTalk Integration Integration Scenarios WCF Send Adapters WCF Receive Adapters Specific Use cases

3 Objectives & Pre-requisites Objectives Focus on Integration issues Present many scenarios of integration Pre-requisites Knowledge in designing and developing with WCF BizTalk

4 Agenda Overview WCF BizTalk WCF-BizTalk Integration Architecture Integration Scenarios WCF Send Adapters WCF Receive Adapters Specific Use cases

5 WCF Service Client Message (SOAP) Message Headers: Addressing, Security, etc Body: Payload Message Service Metadata Services pass messages described by a contract Service may provide metadata Describing the contract Describing the policy it applies to communication

6 Mechanics of Communication Client Service What Contract do I send? Where Address do I send it? How should Binding I send it? Security? Encoding? Transport?

7 Mechanics of Communication Client Service Endpoint Endpoint Address Binding Contract Address Binding Contract Endpoint Address Binding Contract

8 WCF Runtime Architecture

9 Agenda Architectural Overview WCF BizTalk WCF-BizTalk Integration Integration Scenarios WCF Send Adapters WCF Receive Adapters Specific Use cases

10 BizTalk Message Flow XML, Flat File, Binary Orchestration XML, Flat File, Binary Receive Port Send Port Group (optional) Receive Adapter Receive Location Send Port Send Adapter Decrypt Parse Resolve Party Receive Pipeline XML Serialize Sign Encrypt Send Pipeline Tracking Database Message Box Database Management Database

11 Agenda Architectural Overview WCF BizTalk WCF-BizTalk Integration Integration Scenarios WCF Send Adapters WCF Receive Adapters Specific Use cases

12 WCF and BizTalk Server Together Bid Evaluation Order Placement BizTalk Server Capacity Planning Order Receiving Job Costing

13 Integration How? BizTalk Extensibility Point Adapter Framework WCF send and receive facilities are exposed ( to and from) BizTalk through a set of adapters

14 Channel Stack WCF Service Host Operation Operation / Receive Receive Location Location BizTalk Pipeline WCF as Adapter for BizTalk BizTalk WCF Receive Adapter Orchestrations BizTalk WCF Send Adapter Channel Stack WCF Client Send Port BizTalk Pipeline Message Box

15 WCF as Adapter for BizTalk Seven traditional BizTalk adapters WCF-BasicHttp WCF-WsHttp WCF-NetTcp WCF-NetMsmq WCF-NetNamedPipe WCF-Custom WCF-CustomIsolated UI Ensures ease of use and minimizes potential for mis-configuration

16 The Flow

17 Complementary Support WCF platform for building services on Windows Support for Standard communication protocols for services on Windows BizTalk Standards based Integration and BPM Server for Windows Infrastructure for orchestrating and extending WCF services

18 Use Cases Exposing BizTalk orchestration as a WCF service Consuming a WCF service from BizTalk orchestration Transactional Receive and Send Using Headers WS-* headers for routing and message processing Custom headers Using BizTalk as SOAP intermediary

19 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)

20 Integration Made Easy Publishing wizard Publish WCF http service in IIS Publish metadata for in-proc or out-of-proc adapter to IIS Consuming wizard Create message and port types Create a proxy equivalent Bindings file Operation to action mapping

21 Agenda Overview WCF BizTalk WCF-BizTalk Integration Integration Scenarios WCF Send Adapters WCF Receive Adapters Specific Use cases

22 Scenario: Consuming WCF Service BizTalk Messaging Send Port Config. Address Binding Contract Endpoint Address Binding Contract BasicHttpBinding Order Service (WCF) Schema Info, Send Port Config. Info WCF Service Consuming Wizard

23 BizTalk Consuming WCF Service K. Meena Director SymIndia Training & Consultancy Pvt Ltd

24 Scenario: Publish Orchestration as WCF Service Receive Lcation Config. Address Binding Contract BizTalk Orchestration BasicHttpBinding Proxy ABC Details WCF Client SVC Util WCF Service Publishing Wizard Endpoint Info in IIS

25 Orchestration as WCF Service K. Meena Director SymIndia Training & Consultancy Pvt Ltd

26 Scenario Requirement Client App coordinates a Distributed Transaction WCF as Resource Manager BizTalk WCF Receive Adapter as RM Transaction committed only when WCF service commits BizTalk WCF adapter commits Usage of Custom Pipeline component to abort transactions

27 Scenario: Distributed Transactioning Transactions start and end at the message box Transaction Boundary Transaction Boundary Client WCF Adapter WCF Adapter App publish subscribe Message Box

28 Distributed Transactioning Transactions start and end at the message box Transaction Boundary Transaction Boundary Client WCF Adapter WCF Adapter App Message Box

29 Transaction Commited Start Commit Txn Place Order Client Archiving Commit Queue BizTalk Server R2 WCF Adapter Commit WCF Service

30 Transaction Aborted Start Abort Txn Place Order Client Abort Abort Commit BizTalk Server R2 w/wcf Adapter Queue Archiving WCF Service

31 Distributed Transactioning K. Meena Director SymIndia Training & Consultancy Pvt Ltd

32 Scenario Existing WCF Service TransactionFlow is mandatory TransactionScope is required for PlaceOrder method PlaceOrder method If message header BeginNewPO exists, create a key randomly and insert PO into PO table Otherwise, Insert lineitem details in message to PODetails table BizTalk Send Port emits a single document PO master details Multiple PO LineItem details

33 Requirement Need to split the single BizTalk document Create WCF message with header for PO master details Create Multiple WCF messages, one for each Line item Initiate a transaction As part of the same transaction Send WCF message with PO header Send WCF messages for each Line Item

34 Solution Create a Custom Binding Element in WCF WCF Message Interception Split WCF Message into Single message for Order header Multiple messages, one for every Line Item in the order Submit the messages one by one Create a Custom Binding in BizTalk Send Port Use WCF-Custom adapter Configure binding Custom Interceptor, Transaction Flow Encoder Transport

35 Scenario: Custom Binding Element Send Port Config. BizTalk Messaging Address Custom Binding WCF-Custom Inproc adapter CustomBinding= WCFMsgInterceptor, TransactionFlow Text Msg Encoding, Http Transport Contract WCF Service SVC Util WCF Service Consuming Wizard Endpoint Info in IIS

36 WCF Adapter configured with Custom Binding Element K. Meena Director SymIndia Training & Consultancy Pvt Ltd

37 Requirement Orchestration exposed as a WCF service endpoint Secured Access to a BizTalk Receive Location Configurable Windows groups Write a WCF Custom Behaviour and use it while configuring BizTalk Receive location

38 Scenario: Custom Behaviour BizTalk rchestration Receive Location Config. Address WSHttop Binding Contract Custom Behavior Behavior For access check WCF Client

39 WCF Adapter with Custom Behavior K. Meena Director SymIndia Training & Consultancy Pvt Ltd

40 Summary By themselves, WCF and BizTalk add significant value Integrating them provides enhances the value Leveraging Scenarios WS-* standards support of WCF in BizTalk WCF extensibility scenarios are easy configurable in BizTalk BizTalk as a Broker for WCF Services to communicate
