BasicBinding

This sample demonstrates the use of basicHttpBinding that provides HTTP communication and maximum interoperability with first- and second-generation Web services.

Note Note

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

Important note Important

The samples may already be installed on your machine. Check for the following (default) directory before continuing.

<InstallDrive>:\WF_WCF_Samples

If this directory does not exist, go to Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF) Samples for .NET Framework 4 to download all Windows Communication Foundation (WCF) and WF samples. This sample is located in the following directory.

<InstallDrive>:\WF_WCF_Samples\WCF\Basic\Binding\Basic\Http

This sample is based on the Getting Started Sample that implements a calculator service.

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 shown in the following code example.

<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.

To set up, build, and run the sample

  1. Install ASP.NET 4.0 using the following command.

    %windir%\Microsoft.NET\Framework\v4.0.XXXXX\aspnet_regiis.exe /i /enable
    
    
  2. Ensure that you have performed the One-Time Setup Procedure for the Windows Communication Foundation Samples.

  3. To build the C# or Visual Basic .NET edition of the solution, follow the instructions in Building the Windows Communication Foundation Samples.

  4. To run the sample in a single- or cross-machine configuration, follow the instructions in Running the Windows Communication Foundation Samples.
