Download sample

This sample demonstrates the use of basicHttpBinding that provides HTTP communication and maximum interoperability with first- and second-generation Web services. This sample is based on the Getting Started Sample that implements a calculator service.

Note

The WCF samples may already be installed on your machine. Check this (default) directory before continuing: <InstallDrive>:\Samples\WCFWFCardspaceIf this directory doesn’t exist, click the download sample link at the top of this page. Note that this will download and install all of the WF, WCF, and CardSpace samples, you will only have to do this once. The sample is located in the following directory <InstallDrive>:\Samples\WCFWFCardSpace\WCF\Basic\Binding\Basic\Http.

Note

The setup procedure and build instructions for this sample are located at the end of this topic.

The binding is specified in the configuration files for the client and service. The binding type is specified using the binding attribute of the <endpoint> element as shown in the following sample configuration:

<services>
    <service 
        type="Microsoft.ServiceModel.Samples.CalculatorService"
        behaviorConfiguration="CalculatorServiceBehavior">
       <endpoint address=""
             binding="basicHttpBinding"
             contract="Microsoft.ServiceModel.Samples.ICalculator" />
    </service>
</services>

To use the basic binding with default behavior, only the binding section name is required. If you want to configure the basic binding and change some of its settings, it is necessary to define a binding configuration. The endpoint must reference the binding configuration by name by using the bindingConfiguration attribute of the <endpoint> element, as shown in the following sample code:

<services>
    <service 
        type="Microsoft.ServiceModel.Samples.CalculatorService"
        behaviorConfiguration="CalculatorServiceBehavior">
       <endpoint address=""
             binding="basicHttpBinding"
             bindingConfiguration="Binding1" 
             contract="Microsoft.ServiceModel.Samples.ICalculator" />
    </service>
</services>

In this sample, the binding configuration is named "Binding1" and is defined as follows:

<bindings>
   <basicHttpBinding>
      <binding name="Binding1" 
               hostNameComparisonMode="StrongWildcard" 
               receiveTimeout="00:10:00"
               sendTimeout="00:10:00"
               openTimeout="00:10:00"
               closeTimeout="00:10:00"
               maxMessageSize="65536" 
               maxBufferSize="65536" 
               maxBufferPoolSize="524288" 
               transferMode="Buffered" 
               messageEncoding="Text" 
               textEncoding="utf-8"
               bypassProxyOnLocal="false"
               useDefaultWebProxy="true" >
         <security mode="None" />
      </binding>
   </basicHttpBinding>
</bindings>

The binding element provides attributes for setting the host name comparison mode, maximum message size, proxy options, timeouts, message encoding, and other options.

When you run the sample, the operation requests and responses are displayed in the client console window. Press ENTER in the client window to shut down the client.

    Add(100,15.99) = 115.99
    Subtract(145,76.54) = 68.46
    Multiply(9,81.25) = 731.25
    Divide(22,7) = 3.14285714285714

    Press <ENTER> to terminate client.
