WCF Basic Principles

> Developers write services that respond to messagesWCF i t i id th CLR WCF services execute inside the CLR

WCF messages use SOAP model

Services expose addressable endpointsServices expose addressable endpoints

> Services implement contracts that describe messages being exchangedb g a g d Individual contracts are either structural (schema) or

behavioral (interface)

Contracts constrain message flow between initiator and service



AddressAddress Binding Contract(Where) (How) (What)

> Makes an EndPoint uniquely addressable

> Uri based http://localhost/myservice

//l lh / net.tcp//localhost/myservice

> Base address + relative path for each EP http://localhost/myservice

http://localhost/myservice/ep1

http://localhost/myservice/ep2 http://localhost/myservice/ep2

> Normally configured by the Administrator



Bindings Address Binding Contract(Where) (How) (What)

> Bindings determine ‘how’ an endpoint is accessibleC fi th WCF C i ti I f t t Configure the WCF Communication Infrastructure

Transport, Encoding and (WS*) Protocols

WCF bli h bi di fi ti th h t d t> WCF publishes binding configuration through metadata

> Bindings are normally specified in configuration Can be specified in code as well



Contracts Address Binding Contract(Where) (How) (What)

> Contracts describe the external view of a service

> Contracts are exposed through WSDL and XSD

> Contracts are explicitly defined, opt-in model

Types of Contracts

> Service Contract Defines the operations of a service Defines the operations of a service

Each operation defines a Message Exchange Pattern (MEP)– OneWay, Request/Reply and Duplex

> Data Contract Structural “schemas” for data representations

> Fault Contract Defines errors/faults that a service may return so that

consumer applications can handle these situations more consumer applications can handle these situations more gracefully

> Message Contract



g Controls SOAP processing/data model

Metadata

> Describes the capabilities of a service

> Metadata consists of contracts (XSD, WSDL) and Policy

> Metadata can be published through: HTTP Get (baseaddress?wsdl)

WS-Metadata Exchange (MEX)b d l f h d– MEX is a SOAP based protocol for exchanging metadata



Behaviors

> Behaviors determine the local client and service behavior

> Behaviors can be applied through code and configuration> Behaviors can be applied through code and configuration

> Developer vs. Administrator behaviors

Behavior Description

Instancing Specifies the number of instances of services available for handling a message

Concurrency Determines if a service supports single-threaded or multi-threaded modes of operation

Throttling Determines the maximum number of simultaneous i i i direquests, connections, service instances, pending

operations

Exception Handling Determine how exceptions are handled



Security (Impersonations, Authorization), Local Transactions, custom, etc.

WCF Scenarios



WCF CapabilitiesSecurity, Reliable Communication and Transaction

> Security Secure, simple and interoperable, p p Support for Message (WS*) and Transport level security

– Authentication, Authorization, Transfer security

> Reliable Messaging> Reliable Messaging WCF provides reliable communication over unreliable

infrastructure– SOAP based reliable sessions for connected

communicationcommunication– MSMQ based reliability for disconnected

communication

> Transactions> Transactions Transactions ensure Consistency WCF Transaction Scenarios

– Perform an Service Operation as a single transaction



– Perform an Service Operation as a single transaction– Flowing transactions across services
