Level 300What is new in WCF 4 to make it easy?What is AppFabric?WCF + AppFabric = Easy

Warning: Excessive use of implicit, explicit and angle brackets ahead

The big picture of WCF 4

What is new?Configuration defaults, default endpointsWorkflow ServicesHigh performance tracing with ETWNew features for REST-based servicesQueued messaging enhancementsNew protocols

Basic Profile 1.2WS-Discovery and DiscoveryService

RouterServiceNew DataContractResolver, extensibility

My thoughts on WCF

WCF is hardCompared to ASMXConfiguration

BindingsEndpoints

Building ServicesASMX

Write class, add attribute

Expose web methods

Just work with POCO“old” WCF

Interface + Attribute

Write class, add attribute

Data Contracts

Config

Protocol Mappings

<protocolMapping> <clear /> <add scheme="http" binding="basicHttpBinding" bindingConfiguration="" /> <add scheme="net.tcp" binding="netTcpBinding" bindingConfiguration="" /> <add scheme="net.pipe" binding="netNamedPipeBinding" bindingConfiguration="" /> <add scheme="net.msmq" binding="netMsmqBinding" bindingConfiguration="" /> </protocolMapping> Start with this

Eg: http://demo

This is your binding

Default binding config!!!

10

Default Endpoints & Hosts

Self HostSupply base address via code or configExplicit: ServiceHost.AddDefaultEndPoints() Implicit: ServiceHost.Open()

IISBase address is .svc endpointHTTP protocol is provided by defaultProtocols can be added in IIS Manager

11

Are Default Endpoints A Good Thing?

Designed to cater for the current majorityYou may be special

Quota issuesWSHttp or WebHttpMEXLimiting which contracts on which protocols

You can override in machine.config (bad – mostly) or app.config (better – mostly)

Refined Default Config<system.serviceModel> <behaviors> <serviceBehaviors> <behavior> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /></system.serviceModel>

POCO BEFORE .NET 3.5 SP1[DataContract]public class User{ [DataMember] public string FirstName { get; set; } [DataMember] public string LastName { get; set; } [DataMember] public string Username { get; set; } public string Password { get; set; } // do not share}

Explicit

14

POCO FROM .NET 3.5 SP1public class User { public string FirstName { get; set; } public string LastName { get; set; } public string Username { get; set; } [IgnoreDataMember] public string Password { get; set; } // do not share}

IMPLICIT

Been to my other talks?

16

A rose by any other name…

Windows Server AppFabric Contains two key componentsHosting

EndPoint, Windows App Server Extensions, DublinCaching

VelocityNot to be confused with Azure AppFabric

17

N.B. AppFabric

Requires .NET 4 on ServerApplications for not need .NET 4, depends on features

Standalone download or Web Platform InstallerHigh Availability is only in Windows Server 2008 Enterprise & Data Centre
