Communicate over the Internet (WCF)

Use an HTTP binding with WCF.

Again, this is just a configuration change in our working WCF service.

Here’s the server’s app.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="WCFHost.FileService"
               behaviorConfiguration="FileServiceMEXBehavior">
        <endpoint address=""
						binding="basicHttpBinding"
						contract="FileServiceLib.IFileService"/>
						<endpoint address="mex"
						binding="mexHttpBinding"
						contract="IMetadataExchange"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/FileService"/>
          </baseAddresses>
        </host>
      </service>

    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="FileServiceMEXBehavior">
        <!-- Allows metadata to be viewed via a web
             browser or other HTTP request -->
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

					    

Note

To be able to enable an HTTP endpoint under Vista or Windows 7, you need to run this command as an administrator:

netsh http add urlacl url=http://+:PORT/user=MYMACHINE\UserName

Here’s an example:

netsh http add urlacl url=http://+:8080/ user=BEN-PC\Ben

The client’s app.config is shown next:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <bindings>
          <basicHttpBinding>
