CAMP GOLDYCODE CAMPING RESERVATION SYSTEM
A simple service that allows one to make, alter, or cancel a reservation at the Camp Goldy Code CampgroundThe reservation system is available to any client, regardless of type of code, native OS, etc.

SERVICE ORIENTED ARCHITECTURE AND PRINCIPLES
P:5
WHAT IS SERVICE ORIENTATION?
Service-Oriented Architecture (SOA) is a set of principles and methodologies for designing and developing software in the form of interoperable services. These services are well-defined business functionalities that are built as software components (discrete pieces of code and/or data structures) that can be reused for different purposes. SOA design principles are used during the phases of systems development and integration.

WHAT IS WCF?
Windows Communication Foundation (WCF) is a framework for building service-oriented applications. It is a runtime and a set of APIs for creating systems that send messages between services and clients.WCF is the foundation for other distributed technologies by Microsoft, such as Azure, AppFabric, and BizTalkAnd speaking of Azure…– Free 90-day trial at http://www.windowsazure.com– Click “Try It Free”

HOW IT WORKS: A WCF OVERVIEW
P:9
WCF CONTRACTSBuilding out service and data contracts
P:11
CONTRACTS CAN BE KIND OF STICKY…
P:12
WCF CONTRACTS
Contracts determine what data and operations are exposedService contracts define operationsData contracts define the data (duh!)And you’ve got other contracts, too– Message Contracts– Fault Contracts
P:13
A CONTRACT IS JUST A SCHEMA…
P:14
SERVICE CONTRACTS & DATA CONTRACTS
P:15
CONFIGURING THE SERVICE
P:16
BINDINGS
The binding controls the messaging details (what happens on the wire) for that endpoint.Common bindings are common recipes as to how WCF will configure the underlying channel stacks.There are countless extensibility points found throughout the WCF channel layer.

ABC’S: ADDRESS, BINDING, CONTRACT
P:18
HOSTING THE SERVICE
P:19
HOSTING THE SERVICE
A WCF Service is a library, it has no life of its ownThe host brings the WCF service to life by providing the process in which it operates.Most of the time, WCF services will run in a ready-made host environment such as Internet Information Server (IIS) or AzureAnd speaking of Azure…– Free 90-day trial at http://www.windowsazure.com– Click “Try It Free”A lot of things require a host!

USING A WCF SERVICE
P:21
CONSUMING A SERVICE
Because WCF exposes service functionality through open standards, such as SOAP, you can use almost any type of client to consume the service.Allowing a .NET client to consume the service is as easy as creating a service reference or generating a proxy through a command-line utility (svcutil.exe)Non-.NET clients would typically use SOAP to consume a WCF Service
