Address
The location at which
a WCF service can be found. The address incorporates a protocol and URI.
Not dependent on
timing. Each application or command runs in the specified order, but the
specified item does not wait for any previously started processes to finish
before an application or command runs.
A method
call that returns to the caller immediately regardless of whether processing
has completed. The results of processing are returned through another call on
another thread. Asynchronous methods free the caller from having to wait until
processing has finished.
In .NET
Framework security, the process of discovering and verifying the identity of a
principal by examining the user's credentials against some authority.
In .NET
Framework security, the process of limiting access rights by granting or
denying specific permissions to an authenticated identity or principal.
Behavior
In WCF, a way of
customizing the behavior of a client or service.
In WCF, the
transport-level details that define how a client interacts with a service.
Claim
In security, claims are
pieces of information held within a credential.
The behavior and
state that a class provides, which is matched with what a client of that class
can expect to hold. A contract is expressed partly by the signatures for all
public fields, methods, properties, and events of that class. This is augmented
by a description (usually in simple descriptive text) of what each field or
property represents, together with what each method does.
In security, a
credential carries information about a caller, and is used for authentication.
Duplex
When applied to a WCF
contract, indicates independent two-way communication between client and
service.
Encoder
A class that converts
a message into bytes for transmission.
A combination of
address, binding and contract.
NAT
Network Address
Translator. Hardware or software that hides local network addresses behind a
single IP address, translating incoming and outgoing packets as necessary.
SAML
Security Access Markup
Language provides a way to attach credentials to a message.
In WCF, the way
in which a message is secured. Transport mode uses the security of the
transport, while message mode secures the message itself.
Applications
that expose services through interfaces and contracts. Service oriented
applications benefit from being loosely coupled.
A simple, XML-based
protocol for exchanging structured and type information on the Web. The
protocol contains no application or transport semantics, which makes it highly
modular and extensible.
Transport
The underlying
communication protocol. WCF supports three transports: HTTP, TCP and Named
Pipes.
