Default NetTcp Binding

  • Artigo

Download sample

This sample demonstrates the use of the NetTcpBinding binding. This sample is based on the Getting Started Sample that implements a calculator service. In this sample, the service is self-hosted. Both the client and service are console applications.

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\Net\Tcp\Default.

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 in the binding attribute of the <endpoint> element as shown in the following sample configuration:

<endpoint address=""
          binding="netTcpBinding"
          contract="Microsoft.ServiceModel.Samples.ICalculator" />

The previous sample shows how to configure an endpoint to use the netTcpBinding binding with the default settings. If you want to configure the netTcpBinding binding and change some of its settings, it is necessary to define a binding configuration. The endpoint must reference the binding configuration by name with a bindingConfiguration attribute. In this sample, the binding configuration is named Binding1 and is defined as shown in the following sample configuration:

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

<bindings>
  <netTcpBinding>
    <binding name="Binding1" 
             closeTimeout="00:01:00"
             openTimeout="00:01:00" 
             receiveTimeout="00:10:00" 
             sendTimeout="00:01:00"
             transactionFlow="false" 
             transferMode="Buffered" 
             transactionProtocol="OleTransactions"
             hostNameComparisonMode="StrongWildcard" 
             listenBacklog="10"
             maxBufferPoolSize="524288" 
             maxBufferSize="65536" 
             maxConnections="10"
             maxReceivedMessageSize="65536">
      <readerQuotas maxDepth="32" 
                    maxStringContentLength="8192" 
                    maxArrayLength="16384"
                    maxBytesPerRead="4096" 
                    maxNameTableCharCount="16384" />
      <reliableSession ordered="true" 
                       inactivityTimeout="00:10:00"
                       enabled="false" />
      <security mode="Transport">
        <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
      </security>
    </binding>
  </netTcpBinding>
</bindings>

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. Ensure that you have performed the One-Time Set Up Procedure for the Windows Communication Foundation Samples.

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

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

    Note

    Because the server is self-hosted, you must specify an identity in the client's App.config file to run the sample in a cross-machine configuration:

    <client>
  <endpoint name=""
      address="net.tcp://servername:9000/servicemodelsamples/service" 
      binding="netTcpBinding" 
      contract="Microsoft.ServiceModel.Samples.ICalculator">
        <identity>
          <userPrincipalName value = "user_name@service_domain"/>
        </identity>
  </endpoint>
</client>
