Implementing WCF Service Part 2 - Client

I will consume the Customer WCF Service which I developed in Part 1 on WS* Http Binding, you can implement the best security, transactions and many more things using this way. However, I will consume in a very simplistic way in this post. I assume that you have already deployed the WCF Service under IIS and have a working URL ready to be referenced and you are planning to use the customer WCF service in ASPX web Page.

Create a Test Web Site Project using Visual Studio 2008/5 and focus on following 3 files

1.       Web.Config

2.       CustomerWcfServiceTest.aspx – The page you added for testing the WCF Service

3.       CustomerWcfServiceTest.aspmx.vb – Code behind file for WCF Service Test Page

Steps: Right Click on the project and click add the Customer WCF Service using Add Service Reference. Let’s say you give it a name called CustomerWcfService.

 

Web.Config

After adding the above service, verify the web.config file that binding and endpoint information is added to it. This information gets automatically added or removed when you add or remove a service reference. The address will vary as per your machine. You should be able to see like

 

<system.serviceModel>

   <bindings>

    <wsHttpBinding>

    <bindingname="WSHttpBinding_ICustomerService"closeTimeout="00:01:00"

     openTimeout="00:01:00"receiveTimeout="00:10:00"sendTimeout="00:01:00"

     bypassProxyOnLocal="false"transactionFlow="false"hostNameComparisonMode="StrongWildcard"

     maxBufferPoolSize="524288"maxReceivedMessageSize="65536"messageEncoding="Text"

     textEncoding="utf-8"useDefaultWebProxy="true"allowCookies="false">

     <readerQuotasmaxDepth="32"maxStringContentLength="8192"maxArrayLength="16384"

      maxBytesPerRead="4096"maxNameTableCharCount="16384" />

     <reliableSessionordered="true"inactivityTimeout="00:10:00"

      enabled="false" />

     <securitymode="Message">

      <transportclientCredentialType="Windows"proxyCredentialType="None"

       realm="" />

      <messageclientCredentialType="Windows"negotiateServiceCredential="true"

       algorithmSuite="Default"establishSecurityContext="true" />

     </security>

    </binding>

   </wsHttpBinding>

</bindings>

<client>

   <endpointaddress="http://vishwa/ExampleService/CustomerService.svc"

    binding="wsHttpBinding"bindingConfiguration="WSHttpBinding_ICustomerService"

    contract="CustomerWcfService.ICustomerService"name="WSHttpBinding_ICustomerService">

    <identity>

     <dnsvalue="localhost" />

    </identity>

   </endpoint>   

</client>

</system.serviceModel>

Remember, you will be using binding Name WSHttpBinding_ICustomerService for consuming this service in code behind file.

 CustomerWCFServiceTest.aspx: Add the following code inside the body of this page

You are done. Run the project and test the page, you should be able to Add, Modify, Delete and Get Customer records.
