3. Agenda What’s new in WCF 4? Default endpoints
Default bindings and behaviors

Create proxy and call methods
WCF 4
Generate a service interface and class, modify namespace
Expose service operations
Use complex types, serialize public members (POCO)
Generate service reference (proxy)

8. DEMO WCF Simplified Tech Ed North America 2010 1/2/2018 8:56 PM

9. ASMX Equivalence In WCF 4
POCO types introduced with .NET Framework 3.5 SP1
No need to produce data contracts or serializable types for WCF
WCF 4 introduces features to simplify the ASMX equivalent path
Protocol mappings
Default endpoints
Default bindings and behaviors

10. Protocol Mappings Protocol mappings match
Protocol scheme
Binding
Binding configuration (default “”)
Binding defaults are provided by the service model
NOTE: See Machine.config.comments

11. Default Endpoints Generate one endpoint per base address, per contract
Only one base address per protocol (http, net.tcp, net.pipe, net.msmq)
IIS-hosting
Base address is .svc endpoint
HTTP protocol provided by default
Protocols added in IIS Manager
Self-hosting
Supply base address per protocol in config or code
Explicitly call ServiceHost.CreateDefaultEndpoints()
MetadataExchange endpoint added by default
Supports proxy generation

12. DEMO Default Endpoints Tech Ed North America 2010 1/2/2018 8:56 PM

13. Are default endpoints a good thing?

14. Default Endpoints Feel good ASMX-equivalent experience
No need to touch configuration
Administer protocols via IIS Manager
However…
Default bindings usually require some tweaking
BasicHttpBinding is pretty close, could be quota issues
Might want to map HTTP to WSHttp or WebHttp
Developer ultimately has to come up with the right binding configuration
Sometimes want/need more control over endpoints
Which contracts exposed over multiple protocols
Suppressing metadata endpoints
(Look ma! I can do WCF!)

15. Default Bindings and Behaviors
Supply better defaults in the machine or application config
Protocol mappings
Map http protocol to WS2007HttpBinding or WebHttpBinding
And then use default binding
Binding configurations
Provide new defaults for each binding
Behaviors
Provide a default service behavior
All services must share settings

16. What makes a better default?

17. Default Bindings And Behaviors

18. Default Bindings and Behaviors
Heavily influenced by security model
Common scenarios:
Classic Intranet
Anonymous over HTTP
Anonymous over HTTPS/SSL
UserName over SSL
UserName for Certificate
Trusted subsystem / Windows or Certificate
Federated identity

20. Recommendations: Endpoints, Bindings and Behaviors
Automatic endpoints, default bindings and default behaviors are very useful for early prototyping and productivity
You will necessarily make adjustments for protocol requirements
Unless all you want is ASMX
You will control endpoints
Visibility
Not all contracts may be exposed over all protocols
You may choose a few default bindings per protocol
Configure in application config (visibility)
Allow default configuration to be used per endpoint
You may be able to share service behaviors across services
If security behavior is equivalent

21. Configuring WCF Services
For developers
Easier with default endpoints, default bindings, default behaviors
Easier with templates illustrating recommended practices
For IT
How does IT know to adjust relevant settings?
What tools can they use?

22. Troubleshooting WCF Services
For developers
Exceptions during development
Enable trace in configuration
Test again
Search through trace logs (cumbersome)
Difficult to resolve problems involving multiple service calls
For IT
File-based logs inefficient
Performance counters are heavy
May not be able to reproduce issue
Need a way to control monitoring and diagnostic settings
Must not affect system performance

23. Windows Server AppFabric
Technologies for deploying, managing and scaling applications deployed on Internet Information Services (IIS) 7
Manage and monitor services and workflows via IIS Manager and Windows PowerShell (formerly codename “Dublin”)
Distributed in-memory cache (formerly codename “Velocity”)
AppFabric and WCF
Empowers the IT role
Through dashboard can access necessary WCF configuration
Provides immediate visibility into application metrics
Enable monitoring and diagnostics
Leverages high performance ETW tracing
View relevant execution statistics

24. Configuring WCF and WF Settings
Per machine, disable metadata browsing
Per application, enable as desired
Enable or disable metadata endpoints

25. Configuring WCF and WF Settings
Per machine, enable Health Monitoring
Per application, use Troubleshooting as needed
Enable message logging as needed
NOTE: can customize profiles!

26. Configuring WCF and WF Settings
Per machine, disable auto-start to conserve resources
Per application, likely to opt-in depending on availability requirements
Required for services hosted with the Windows Azure AppFabric Service Bus

27. Configuring WCF and WF Settings
Per machine, set defaults for throttling
Per application, may require adjustments for load
Throttles are very important to WCF service scalability and throughput!
WCF 4 throttling defaults are much better

28. Configuring WCF and WF Settings
Per machine, not likely to set certificate
Per web site, good place to set default cert for site
Per application, may adjust per application

29. WCF and Windows Server AppFabric

30. Summary WCF can be as easy as ASMX WCF 4 simplifies configuration
If you don’t need additional features
WCF 4 simplifies configuration
Reduced footprint
Centralize defaults (and customize them)
AppFabric provides useful administrative and troubleshooting tools
IT administrator can configure appropriate settings
Developers can troubleshoot code locally, more easily
Easier to track down issues on production servers
