Term | Definition |
address | Specifies the location where messages are received. It is specified as a Uniform Resource Identifier (URI). The URI schema part names the transport mechanism to use to reach the address |
application endpoint | An endpoint exposed by the application and that corresponds to a service contract implemented by the application. |
behavior | A behavior is a component that controls various run-time aspects of a service |
binding | Defines which communication protocols are used to communicate with WCF services. It is constructed of a set of components called binding elements that stack one on top of the other to create the communication infrastructure. See endpoint. |
channel | A concrete implementation of a binding element. The binding represents the configuration |
claims-based security | Allows authorized access to protected resources based on claims. |
client application | A client application is a program that exchanges messages with one or more endpoints. The client application begins by creating an instance of a WCF client and calling methods of the WCF client. It is important to note that a single application can be bot |
coding | Allows the developer to retain strict control over all components of the service or client |
configuration | Configuration has the advantage of allowing someone other than the developer (for example |
contract | A contract is a specification of support for the particular type of contract that it is. A service contract |
data contract | The data types a service uses must be described in metadata to enable others to interoperate with the service. The descriptions of the data types are known as the data contract |
declarative application | An application that is described sufficiently to be created at runtime without running imperative instructions. |
endpoint | Consists of an address |
endpoint address | Enables you to create unique endpoint addresses for each endpoint in a service |
fault contract | A fault contract can be associated with a service operation to denote errors that can be returned to the caller. An operation can have zero or more faults associated with it. These errors are SOAP faults that are modeled as exceptions in the programming m |
hosting | A service must be hosted in some process. A host is an application that controls the lifetime of the service. Services can be self-hosted or managed by an existing hosting process. |
hosting process | A hosting process is an application that is designed to host services. These include Internet Information Services (IIS) |
initiating operation | An operation that is called as the first operation of a new session. Non-initiating operations can be called only after at least one initiating operation has been called. |
instancing model | A service has an instancing model. There are three instancing models: “single” in which a single CLR object services all the clients; “per call” in which a new CLR object is created to handle each client call; and “per session |
message | A message is a self-contained unit of data that may consist of several parts |
message contract | A message contact describes the format of a message. For example |
message security mode | Message security mode specifies that security is provided by implementing one or more of the security specifications. Each message contains the necessary mechanisms to provide security during its transit |
metadata | The metadata of a service describes the characteristics of the service that an external entity needs to understand to communicate with the service. Metadata can be consumed by the ServiceModel Metadata Utility Tool (Svcutil.exe) to generate a WCF client a |
operation contract | An operation contract defines the parameters and return type of an operation. When creating an interface that defines the service contract |
projection | The representation of data on the wire. For example |
security | Security in WCF includes confidentiality (encryption of messages to prevent eavesdropping) |
self-hosted service | A self-hosted service is one that runs within a process application that the developer created. The developer controls its lifetime |
service | A program or process that exposes one or more endpoints |
service contract | The service contract ties together multiple related operations into a single functional unit. The contract can define service-level settings |
service operation | A service operation is a procedure defined in a service's code that implements the functionality for an operation. This operation is exposed to clients as methods on a WCF client. The method may return a value |
system-provided bindings | WCF includes a number of system-provided bindings. These are collections of binding elements that are optimized for specific scenarios. For example |
terminating operation | An operation that is called as the last message in an existing session. In the default case |
transport security mode | Security can be provided by one of three modes: transport mode |
transport with message credential security mode | This mode uses the transport layer to provide confidentiality |
type converter | A CLR type can be associated with one or more System.ComponentModel.TypeConverter derived types that enable converting instances of the CLR type to and from instances of other types. A type converterr is associated with a CLR type using the System.Compone |
WCF client | A WCF client is a client-application construct that exposes the service operations as methods (in the .NET Framework programming language of your choice |
workflow services | A workflow service is a WCF service that is implemented as a workflow. The workflow contains messaging activities that send and/or receive WCF messages. |
WS-* | Shorthand for the growing set of Web Service (WS) specifications |
XAML | eXtensible Application Markup Language |
XAML schema | A markup schema used to define custome types in XAML. |
