 WS-* Interoperability
 Integration with legacy systems.

Implementation

2. Interoperability
 Ability to communicate with other platforms
thru standard protocol like SOAP.
 SOAP is platform independent.
 To achieve interoperability WCF team
generated
many compatibility tests for a subset of
different vender specifications.
 Microsoft created WCF interoperability Plug-
Fest #
 Sun is one of the participants.CA 907 WCF

3. Interoperability
 Sun web services team worked with Microsoft
WCF team.
 They released open source framework –
Project Tango1
which focuses on
interoperability with WCE.
 It has evolved into Web Services
Interoperability Technology(WSIT)2
 Another major participant in the WCF/.NET
interoperability is Axis Project from Apache
Software Foundation 3

 One of the earliest efforts is to implement WS-
I Basic Profile.

5. Interoperability
WS-I Basic Profile
 Some venders had chosen different versions
of WSDL or SOAP.
 So getting interoperability among diff. system
is very difficult.
 The early SOA vendors did not confirm to
open standards, so true interoperability
between different vendors is very difficult.

6. Interoperability
WS-I Basic Profile
 Major participants form Web Services
Interoperability (WS-I) organization to develop
web services standard in non- proprietary and
open manner.
 Currently appox. 90 organizations are
participating.

7. Interoperability
WS-I Basic Profile
 Core components
- In April 2004 WS-I released version 1.0.
- This set of specifications laid the groundwork
for vendors and customers to form strong
base.
- Many companies and open sources groups
recognized that market will no longer allow
stand alone proprietary interoperability stack.

8. Interoperability
WS-I Basic Profile
 Core components
- S0AP 1.1 - WSDL 1.1 - UDDI 2.0
- XML 1.0 - XML Schema Part1:
Structures
- XML Schema Part 2: Datatypes
- SSL Version 3.0
etc….

9. Interoperability
WS-I Basic Profile
 ASP.NET Support for basic profile
- Initially it did not support basic profile 1.0.
- With ASP.NET 2.0 support for basic profile
1.1 was available

10. Interoperability
Web Service protocol support by WCF
 BasicHttpBinding
- Supports WS-Basic Profile 1.1
- Allows to create endpoint which can
communicate with *.asmx based web services.
 WSHttpBinding
- Basic + secure+reliable sessions.

11. Interoperability
Web Service protocol support by WCF
 WSDualHttpBinding
- Copy of WSHttpBinding but it supports
duplex
WCF Services are compatible with Web Service
Enhancement(WSE 3.0)

12. Integration
 Process of linking together different computing
systems and software applications physically
or functionally, to act as a unit.
 WCF supports COM+ Integration, MSMQ

13. Chapter 13 Deploying WCF
 Installing WCF Services
 Upgrading existing services
 Troubleshooting WCF service installations.

14. Installing WCF Services
 Operating System support
- Windows XP SP2
- Windows Server 2003 with SP1
- Windows Vista (WCF is installed)
- Window 7
 Required Software
- .NET Framework 3.0, 3.5 and …
- IIS(Internet Information Services)
- MSMQ(MicroSoft Message Queuing)

15. Installing WCF Services
 .NET Framework
- http://www.microsoft.com/en-
in/download/details.aspx?id=22
- Needed on machine in which you want to run

16. Installing WCF Services
 IIS
- Needed on machine in which you want to
Host WCF Service
- To install it open control panel add
remove programs Add/Remove Windows
Components

19. Installing WCF Services
 Hosting on IIS
- Create virtual directory in
c:inetpubwwwroot directory
- Copy of publish .svc and config files (see
demo)
 Hosting as Windows Service
- Create .exe of your host application.
- Install it by using installutil.exe
- Start service by net start command
- Stop service by net stop command

20. Upgrading Services
 Upgrading in IIS is very easy copy or republish
the assembly, config, svc files and you are
done.
 In Window Service you need to restart service
manually after doing changes in your code. So
that the changes are available.

21. Trouble Shooting WCF
installations
 Client/Server Communications
- It client cannot communicate with service
then problem might not be with client only.
- Start looking at service first, by using
svcutil.exe
- On IIS try the address of service in browser.
- If both options are ok then problem is on
client side.
- Review client config file.

22. Trouble Shooting WCF
installations
 Unexpected Service behavior
- Reason is unhandled exception.
- It can be monitoring by setting
IncludeExceptionDetailInFaults=true either in
code or config.
- After testing you can turn it off.
- You can also see Trace viewer, Message
logging
