Windows Communication Foundation Extensibility Samples

The samples in this section demonstrate some Windows Communication Foundation (WCF) extensibility scenarios.

In This Section

• DataContract Surrogate
  Demonstrates how processes such as serialization, deserialization, schema export, and schema import can be customized using a data contract surrogate class. This sample shows how to use a surrogate in a client and server scenario where data is serialized and transmitted between a WCF client and service.

• Extending Control Over Error Handling and Reporting
  Demonstrates how to extend control over error handling and error reporting in a WCF service using the IErrorHandler interface.

• Operation Formatter and Operation Selector
  Demonstrates how WCF extensibility points can be used to allow message data in a different format from what WCF expects. By default, WCF formatters expect method parameters to be included under the <soap:body> element. The sample shows instead how to plug in a custom operation formatter that parses parameter data from an HTTP GET query string and invokes methods using that data.

• Custom Service Host
  Demonstrates how to use a custom derivative of the ServiceHost class to alter the run-time behavior of a service. This approach provides a reusable alternative to configuring a large number of services in a common way. The sample also demonstrates how to use the ServiceHostFactory class to use a custom ServiceHost in the Internet Information Services (IIS) or Windows Process Activation Service (WAS) hosting environment.

• Instancing Extensibility Samples
  Demonstrates WCF instancing extensibility scenarios.

• Custom Message Filter
  Demonstrates how to replace the message filters that WCF uses to dispatch messages to endpoints.

• Parameter Filter
  Demonstrates how to validate the parameters passed to a method before it is invoked.

• Message Inspectors
  Demonstrates how to implement and configure client and service message inspectors.

• Metadata Extensibility Samples
  Demonstrates WCF metadata extensibility scenarios.

• Interoperable Extensibility Samples
  Demonstrates WCF interoperable extensibility scenarios.

• Binding Extensibility Samples
  Demonstrates WCF binding extensibility scenarios.

• Transport Extensibility Samples
  Demonstrates WCF transport extensibility scenarios.

• Message Encoder Extensibility Samples
  Demonstrates WCF channel extensibility scenarios.

• Message Encoder Extensibility Samples
  Demonstrates WCF message encoder extensibility scenarios.

• Rules-Driven WCF Router
  Uses the Windows Workflow Foundation (WF) rules engine to implement the core router functionality that determines where to forward a given message.

• Security Extensibility Samples
  Demonstrates WCF security extensibility scenarios.

• File Persistence Provider Sample
  Demonstrates how to create a persistence provider that works with durable services.

• Web Programming Model Extensibility Samples
  Demonstrates how to use the extensibility model for the WCF Web programming model.

• Syndication Extensibility Samples
  Demonstrates how to use the extensibility model for WCF syndication feeds (ATOM/RSS).

• JSON with Padding (AJAX)
  Demonstrates support for JSON with Padding (JSONP) in WCF services.
