- Multiple platforms
- Communication between applications is permissible
- Allows multiple clients to access the same services
Features of WCF
One of the key features of WCF is that it facilitates you to produce service oriented applications. With the ability to send and receive data via the web, Service-oriented architecture (SOA) is one of the key applications developed. The varied service oriented applications created can easily interconnect with any platform and any service as long as the essential contracts are met.
WCF gives an immense amount of leeway regarding interoperability. With WCF providing various Web Services(WS) infrastructure protocols through various channels and WS application protocols, it is only natural that interoperability is activated. This enables the various WS application protocols for interoperability based on different languages such as XSD and WSDL.
Multiple Message Patterns
Every platform facilitates the ability to enable multiple message patterns through the use of WCF. Some of the message patterns that help in communication include the request/reply pattern, one-way message pattern, the duplex exchange pattern etc.
All data contract entities, involved in realization of service operation comprise service metadata. WCF sustains circulating service metadata using formats like WSDL, XML Schema and WS-Policy. This metadata is utilized to instinctively generate and organize clients for gaining access to WCF services.
A data contract is an official contract between a service and a client that theoretically explains the data to be exchanged. Data contract is known to be explicit or implicit. WCF outlines implicit contracts for built-in types such as int and string, but explicit opt-in data contracts can be easily defined for custom types.
Security in WCF provides Authentication, Authorization, Integrity and Confidentiality. Messages are encrypted to guard privacy and users are requested to identify themselves before being allowed to receive messages. Security can be employed using well-known standards such as SSL or WS-SecureConversation.
Multiple Transports and Encodings
Messages can be sent on any of several built-in transport protocols and encodings. The most common protocol and encoding is to send text encoded SOAP messages using is the HyperText Transfer Protocol (HTTP) for use on the World Wide Web. Alternatively, WCF allows you to send messages over TCP, named pipes, or MSMQ. These messages can be encoded as text or using an optimized binary format. Binary data can be sent efficiently using the MTOM standard. If none of the provided transports or encodings suit your needs you can create your own custom transport or encoding. For more information about transports and encodings supported by WCF see Transports in Windows Communication Foundation.
Reliable and Queued Messages
WCF enables reliable message exchange through dependable sessions applied via WS-Reliable Messaging and using MSMQ. WCF provides support for queuing by using Microsoft Message Queuing (MSMQ) as a transport. WCF also enables disconnected communication between client and service via queued calls. This enables possibilities such as load-balancing, enhanced availability and recompensing work.
WCF supports durable messages. Durable messages are the ones which are never lost because of any kind of disruptions at the time of contact. These messages are frequently saved in the database, so that messages are retrieved in case of loss of connection.
WCF Transactions is unlike other languages. You can merge your message and database operation in single unit in WCF. WCF enables transactions using one of 3 transaction models that include WS-AtomicTtransactions, the APIs in the System.Transactions namespace, and Microsoft Distributed Transaction Coordinator. Some of the attributes that feature in WCF Transcations models are the ServiceBehavior attribute, the OperationBehavior attribute, and the TransactionFlow attribute.
AJAX and REST Support
Representational state transfer (REST) is a style of software architecture for distributed hypermedia systems such as the World Wide Web. REST is an example of an evolving Web 2.0 technology. WCF Rest Services are normal WCF Services that have added functionality with an edge of Ajax.
The WCF architecture has numerous of extensibility possibilities. If additional facility is needed, there are various entry points that permit you to modify the behavior of a service. WCF extensibility can be created through Managed Extensibility Framework (MEF) as it provides you with a lifetime management option and has a strongly typed metadata.
