WCF Presentation pptx

MSDN Getting Started with WCF Tutorial, Understanding Events in WCF - Codeproject, Understanding Operation Types - communication modes

Note: These examples won't run until you have completed the setup described in the previous lecture page. That's because most of them host in Internet Information Server (IIS). Microsoft is using only one web application to run any of them and the setup is required for that application switching to work work in IIS. The same is true for all the Microsoft samples (see Previuos lecture page).

WCF Self Host Service
Microsoft's calculator service, used in many of the MS WCF Samples
WCF Instances
Show how to use each of the three server activation models using Microsoft Calculator service.
WCF Message Concurrency
Explore effects of message concurrency using Microsoft Calculator service.
WCF Message Passing
Illustrate use of message contract with Microsoft Calculator service.

Note: These examples do not need the setup described in the last lecture. Most of them self-host in windows applications. The few that do use IIS each supply their own web application.

Most of the examples here are simple demos and have very little error handling. To show you how to add error handling I've taken one of the examples, BasicService - Programmatic, with no error handling, and added that in BasicService - Programmatic Version 2, with exception handling for each of the service methods. See comments in the handout. You will find that enhanced demo in the folder here.

Service Object Lifetimes - Instancing

Hand Crafted WCF Services - BasicHttp
Hand Crafted WCF Services - WSHttp
Builds services without using the WCF wizard. Both declarative and programmatic construction of channels are illustrated.

WCF Wizard-based Service
This project shows you what the C# WCF wizard generates. It's probably easier to start from one of my projects.
Self-Hosted Strings Service
Demonstrate service sending strings by value, reference, and receiving out string.

Self Hosted File Service
Illustrates how to send files in chunks using a WCF service.
Timed File Streaming Service
Illustrates how to use streaming (inherently chunks) of binary files.

WCF Message Passing Communication
Show how to build a simple, effective message-passing system using WCF data contract.
WCF Peer-To-Peer Communication
This example uses both WCF and WPF to build a chat like facility.
