Keith Elder's WCF presentation @ VSdotNetUG.org

A test client for WCF inside the first few minutes!
WCF Test Client is a WCF Service Host ... nice to run with F5 instantly. (but we know that we want to create a real service host ourselves later, or just use IIS)

WCF Service Host is useful for testers... they script against it.

Great tool:
+ double-click on the GetData (vanilla out of the box), new tab with the "Invoke" button.
+ double-click on the GetDataUsingDataContract (vanilla out of the box), new tab with the "Invoke" button.
+ Invoke, and it shows results
+ Invoke, and you have two tabs: Formatted and XML so you can see the raw data (like if you had issues)

ASMX not really usable in WinForms. WCF is.
ASMX is not as performant either... nor is security as simple.

AJAX == JSON -> attribute
Twitter == REST api -> attribute

Request, no reply ex: MSMQ ... IsOneWay ex: OperationClient(IsOneWay) on the interface
Request, Reply (normal)
Duplex (Dual) ex: massively online gaming - XBox Live

MessageHeader if you need absolute control over ordering for interoperability.

... Too too much to keep up the blogging on while watching.
You'll have to see Keith's presentation to understand how much.

The best parts
+ use of the WcfTestClient
+ WAS - Windows (process) Activation Service
+ timing shows that net.tcp beats http by about 33%, and net.msmq beats tcp by even more.

more later...
