Programming WCF Services

Chapter 1. WCF Essentials This chapter describes the essential concepts and building blocks of WCF and its architecture, enabling you to build simple services. You will learn the basic terms regarding addresses, bindings, contracts, and e...

Chapter 2. Service Contracts The ServiceContract attribute presented in the previous chapter exposes an interface (or a class) as a service-oriented contract, allowing you to program in languages like C#, using constructs like interfaces,...

Chapter 3. Data Contracts In the abstract, all that WCF provides for is the ability to host and expose native CLR types (interfaces and classes) as services, and the ability to consume services as native CLR interfaces and classes. WCF se...

Chapter 4. Instance Management Instance management is the name for a set of techniques used by WCF to bind client requests to service instances, governing which service instance handles which client request. You need instance management b...

Chapter 5. Operations The classic object- or component-oriented programming models offered only a single way for clients to call a method: the client would issue a call, block while the call was in progress, and continue executing once th...

Chapter 6. Faults Any service operation can at any moment encounter an unexpected error. The question is how (if at all) that error should be reported back to the client. Concepts such as exceptions and exception handling are technology-s...

Chapter 7. Transactions Transactions are the key to building robust, high-quality service-oriented applications. WCF provides simple, declarative transaction support for service developers, enabling you to configure parameters such as enl...

Chapter 8. Concurrency Management Incoming client calls are dispatched to the service on threads from the thread pool. Since multiple clients can make multiple concurrent calls, the service itself can sustain those calls on multiple threa...

Chapter 9. Queued Services WCF enables disconnected work between clients and services. The client posts messages to a queue, and the service processes them. Such interaction enables different possibilities, and in turn a different program...
