Agenda What’s new in WCF 4? Default endpoints Default bindings and behaviors Recommendations for defaults What is Windows Server AppFabric? Simplified WCF configuration and troubleshooting

Who Is This Session For?

WCF 4 WCF 4 released April 2010 WCF 4 enhancements Part of Visual Studio 2010 and .NET Framework 4 WCF 4 enhancements Configuration defaults, default endpoints High performance tracing with ETW New features for REST-based services Queued messaging enhancements WCF Workflow Services New protocols Basic Profile 1.2 WS-Discovery and DiscoveryService RouterService New DataContractResolver, extensibility Our focus + AppFabric

Is WCF Hard?

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

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

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

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

Are default endpoints a good thing?

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!)

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

What makes a better default?

Default Bindings And Behaviors Tech Ed North America 2010 1/2/2018 8:56 PM Default Bindings And Behaviors DEMO © 2010 Microsoft Corporation. All rights reserved.

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

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

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?

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

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

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

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!

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

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

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

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
