Windows Communication Foundation are Confidentiality, Integrity, Auditing, Authentication and Authorization. In Windows Communication Foundation, security can be configured at two different levels: Transport Level Security It secures the actual transport (i.e. the pipe) over which the message passes through from client to a service. For example it uses SSL (Secure Socket Layer) to ensure point-to-point protection. […]
Microsoft Windows Communication Foundation comes with a set of built-in bindings and each binding is designed to fulfill some specific need. So, if interoperability is our concern and we need to communicate with non-WCF system, then, we should go for basicHttpBinding or wsHttpBinding. BasicHttpBinding WsHttpBinding Primarily BasicHttpBinding is designed to exchange SOAP over HTTP(s) only, […]
In this article, we will have a look into new and important features in major versions of Windows Communication Foundation starting from WCF 3.5 to WCF 4.5. What’s new in vWCF3.5? WCF support for REST Style Services by introducing Web programming model using rich features of HTTP instead of just a transport. In order to […]
As we know that with previous versions of WCF, WSDL (Web Service Description Language) file does not contain Data Contracts of the service. XSD files contains the Data Contracts and WSDL has import directives for the those XSD files. Due to this dependency on other files, processing of such WSDL file by some third-party was […]
Validating configuration is another new features in Windows Communication Foundation v4.5. Basically, it can be considered as an enhancement to Visual Studio as well. Previously, config files were not validated if we build our WCF project. Now with WCF 4.5, if we build our project and our configuration file has some validation issue, […]
Windows Communication Foundation is a great programming platform for building service-oriented applications. However, you will find out that most of WCF developers had a concern that it has lengthy and complex configuration settings. If you ever workedwithprevious versionsofWCF,youmust be familiar with following configuration.
<binding name=”WSBinding” closeTimeout=”00:01:00? openTimeout=”00:01:00?
receiveTimeout=”00:10:00? sendTimeout=”00:01:00? bypassProxyOnLocal=”false”
messageEncoding=”Text” textEncoding=”utf-8? useDefaultWebProxy=”true”
<readerQuotas maxDepth=”32? maxStringContentLength=”8192? maxArrayLength=”16384?
maxBytesPerRead=”4096? maxNameTableCharCount=”16384? />
<reliableSession ordered=”true” inactivityTimeout=”00:10:00?
<transport clientCredentialType=”Windows” proxyCredentialType=”None”
<extendedProtectionPolicy policyEnforcement=”Never” />
<message clientCredentialType=”Windows” negotiateServiceCredential=”true”
algorithmSuite=”Default” establishSecurityContext=”true” />
Above configuration is the default binding configuration generated on client-side when you add […]
As we know that with previous versions of Windows Communication Foundation, while creating proxy using SvcUtil.exe tool, the output generated file contains the Service Contract, Client operations as well as Data Contracts. There was no way to generate the Service Contract only. But with Windows Communication Foundation v4.5, now its possible to generate the Service Contract only using SvcUtil.exe tool as follows:
svcutil.exe “http://localhost:MyWCFService/Service1.svc?wsdl” /serviceContract
