applications, across a local network and over the internet.
WCF Service:
WCF
service is a program that exposes collection of endpoints. Each endpoint is a
portal for communicating to and fro from another network. All communications
taken place through the endpoint. End point consists of three components (i.e.
Address, Binding & Contract).
Additional Information On WCF:
Windows communication foundation
is designed to offer a manageable approach
to provide
- distributed computing,
- broad interoperability, and
- direct support for service
orientation
WCF simplifies development of connected applications through a new service-oriented
programming model.
The typed
programming model (called the service model) is designed to ease the development
of distributed applications and to provide developers with expertise in ASP.NET
Web
The Microsoft Platform for
SOA for building distributed and interoperable applications
It Unifies
- ASMX,.NET Remoting and
Enterprise Services Stack
- A Single programming model
for all
- Configuration drives
protocol choices, messaging formats ,process allocation, etc.
Service Oriented
- Built for service oriented
system design
- Simplifies how you approach
SOA
- Introducing a API between
Functionalities and Service is called CONTRACTS
Loosely Coupled
- Not bound to any protocol
in encoding format or hosting environment
- It can accessed from using
any of the protocol like TCP,HTTP etc
- Everything is configurable
- Note-Loosely Coupled and
everything is configurable as part of the Deployment and NOT as part of
the Development
Interoperable
- Supports core web services
standards
- Ratified and not –yet
ratified
- Extensible to quickly adapt
to new protocols and updates
Integration
- Integrates with earlier
Microsoft stacks like COM, Enterprise services, MSMQ
