2010• MSDN Forums

Poster, Moderator• Active in testing

Connect releases – VS 2010

Objectives and Takeaways• Introductions • Overview of the WCF LOB SDK• Demo - SqlBinding• Architecture of the SDK• Enterprise LOB and Generic Datasource Scenarios• Demo - SalesForceBinding

OVERVIEW OF THE WCF LOB SDK

What is the WCF LOB SDK?• Free Toolkit from Microsoft based on WCF

custom bindings• Provides client manageability, usability

improvements for using custom bindings• LOB = [classic ERP] datasource • Can be used for any system that needs to

provide metadata or context to developers• Architectural foundation for BizTalk Adapter Pack

What is provided?• VS client-side integration• Wizards for creating custom binding adapters

(Code gen)• Metadata explorer• WCF Service wrapper extension• SDK, samples• Add custom binding to machine.config code• Setup project example

Comparing WCF and WCF LOB SDK

WCF• Service, client• Default, standard

bindings• Custom bindings based

on binding elements• Add Service Reference• .NET compatible config

file elements

WCF LOB SDK• Adapter, client, optional

service• Custom bindings based

on binding elements• Add Adapter Service

Reference• .NET compatible config

file elements

Demo - Using the sqlBinding in VS 2008

Observations• Wizard-like form similar to Add Service Ref• Object browser enables quick selection of

datasource objects• After wizard executes, new proxy class added• DataContracts created for parameters, results• When used with BizTalk, XSDs are generated• Proxy generation options like with SvcUtil

Questions?

FAQ:• What about VS 2010 support?• The add adapter service reference not showing

up after install. Why?• Compatible w/ EF?

ENTERPRISE LOB & GENERIC DATASOURCE SCENARIOS

Enterprise LOB Scenario• Enterprise system storing data: SAP, Oracle,

PeopleSoft, Siebel, CRM, etc.• System-specific formats, connectivity, supporting

infrastructure• WCF LOB SDK provides foundation for custom

bindings/adapters based on your code:– Example: Custom Oracle binding from WCF LOB SDK +

ODP.Net APIs

• WCF LOB SDK service wrapper acts as protocol transition/bridge layer

Generic Datasource Scenario• LOB<T> where T : YourDataSource• Foundation for exposing data or O/R layer• Middle tier service layer• CSLA service layer

Other Uses for the SDK• Client for connecting to ESB or SOA resources• Light weight UDDI explorer• Centralize connectivity management• Client for missing VS functionality – for

referencing Web 2.0 services

Questions?

FAQ:• What are the licensing terms of the BizTalk

Adapter Pack?• What do you mean by “protocol transition” or

“protocol bridging”?

Component Architecture

WCF LOB SDK Development Lifecycle• Wizard based metadata code generation• Setup projects based on samples• Connection, URI, Property Grid Type Editors• Binding Elements if required• Metadata Browser and Search• WSDL customizations

Demo – SalesForce CustomBinding• No supported SalesForce VS extension

currently was available• SalesForce provides REST and SOAP APIs

but has specialized implementation• Async operations only exposed on REST,

would be useful if called via SOAP and bridged from REST

APPENDIX

Example of a custom binding (WCF)<configuration> <system.serviceModel> <bindings> <customBinding> <binding name="myBinding"> <textMessageEncoding

messageVersion="Soap11" /> <httpTransport /> </binding> </customBinding> </bindings> <services> <service behaviorConfiguration="WcfServiceLibrary1.Service1Behavior"

name="WcfServiceLibrary1.Service1"> <endpoint address="" binding="customBinding" bindingConfiguration="myBinding" contract="WcfServiceLibrary1.IService1"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost:8731/Design_Time_Addresses/WcfServiceLibrary1/Service1/" /> </baseAddresses> </host> </service> </services>

Comparing WCF LOB with BizTalk

WCF LOB SDK• Custom Binding centric• Custom Bindings shown

in Add Adapter Service wizard

• .NET project: add adapter service

• Generates client proxy

BizTalk• Adapter centric• Custom Bindings shown

in WCF-Custom adapter• BizTalk project: Add

generated items \ consume adapter service

• Generates BizTalk schema, binding file
