With the .NET Framework 3.5 release, WCF added support for building REST style services. REST support within WCF was enhanced with the release of .NET Framework 3.5 SP1 to add make REST development easier and to support the ADO.NET Entity Framework entities in WCF contracts. REST Starter kit released independently of .NET framework improves development productivity by providing additional

Read about ASP.NET Partial Trust environment. Currently WCF provides very little support for partial trusted environment. When hosting in medium trust environment - only basicHttpBinding is supported by default. If you want to use wsHttpBinding, security mode needs to be set as 'None' or 'Transport'. Default security mode for wsHttpBinding is 'Message'. Partially trusted callers are

Dear Readers, I will be blogging exclusively on Windows Communication Foundation from July 30th for 3 weeks till 20th August. It will start with the most basic tutorials & concepts and move towards advanced one. I am also going to cover some posts on how to migrate from Remoting to WCF for existing users. So, Pls join me by giving your ideas and feedback on this great technology.

Following are the various options available today for hosting WCF service with the features provided by them : 1. Self Hosted : Console application, Easy to deploy, not recommended for production environments. 2. Windows Service : no IIS required, Robust environment, message-activation not supported, recommended for light weight/use services. 3. IIS 5.1, IIS 6.0 : all the health controlling/

Securing Services involves four aspects mainly : 1. Authentication : Who the client is and whether it is allowed to communicate with service. 2. Confidentiality : Encrypting communication between client and service. 3. Integrity : To make sure that the communication is tamper proof. 4. Authorization : The access or execution rights of the client with respect to the service. The various modes of

Metadata endpoints are like any other endpoints and are used by service providers to publish metadata of their services in a more standard way. Metadata of a service can be retrieved either by using a WS-Transfer GET request or a HTTP/GET request using the ?wsdl query string. In the below example adding <serviceMetadata> element in behaviour and adding endpoint to publish it will enable

All communication in WCF happens through endpoints. Each endpoint contains following details : 1. Address of the endpoint. It uniquely identifies the endpoint. 2. Binding information for the client. 3. Contract that identifies the methods available. Sample config file : In the below config the endpoint has base address while the second end point has address as baseAddress/mex <?xml version="

Bindings contain details which are required to an endpoint of WCF Service. The information contained in Bindings can be classified mainly into three categories : 1. Protocols : details of security mechanism, transaction context, reliable messaging requirements etc. 2. Encoding : details about message encoding like text or binary. 3. Transport : Transport protocol to use like http or binary. The

WCF has primarily three types of contracts :service contractThe contract defines the name of the service, its namespace, and other global attributes. The contract is defined by creating an interface and applying the ServiceContractAttribute attribute to the interface.operation contractthe operation contract define the parameters and return type of an operation. When creating an interface that

WCF is basically a message based architecture where clients and servers communicate using messages instead of remote invocation like DCOM.Currently WCF supports three message patterns :One way messaging : client sends a message to service without expecting a response backRequest – Response : client sends a message and waits for replyDuplex Messaging : client & service send message to each
