\viewkind4\uc1\pard\lang2052\f0\fs20 Hi Scott,
\par
\par From your description ,I understand you want to convert a .NET remoting service to WCF hosted. However, you met some problems on converting a singleton SAO since it uses dynamically assigned listening port, so you're wondering how to do this in WCF, correct?
\par
\par If your main concern is dynamically configuring service port. I think you can consider do the ServceHost creation programmatically. Thus, you can use code to specify the baseAddress or subaddress for each endpoint of the service.
\par
\par I've found two web articles which provide some sample code on creating WCF service host programmtically. They also include the code that supplyl the service's address(include port)

\par
\par Hope this helps some.

\par
\par I have a small program that exposes an interface via soap as follows:
\par
\par HttpChannel ipc = new HttpChannel( nPort );
\par ChannelServices.RegisterChannel( ipc, false );
\par RemotingConfiguration.RegisterWellKnownServiceType(
\par typeof(WsdlClient.CJLResponse), "JLSoapResponse.rem",
\par WellKnownObjectMode.Singleton );
\par
\par This works fine. Note that the port the program is listening on varies. This
\par allows for multiple instances of the program to run concurrently.
\par
\par I want to convert this to its WCF equivalent.
\par
\par I am current using the following configuration which works for a single
\par instance but not for multiple.
\par
\par <system.serviceModel>
\par <services>
\par <service name="WsdlClient.CJLResponse"
\par behaviorConfiguration="SoapRspService">
\par <host>
\par <baseAddresses>
\par <add baseAddress="http://xx.xx.xx.xx:5300/JLSoapResponse.wcf"/>
\par </baseAddresses>
\par </host>
\par <endpoint address=""
\par \tab\tab\tab\tab\tab binding="basicHttpBinding" bindingConfiguration="SoapRspBindingBasicHttp"
\par \tab\tab\tab\tab\tab\tab contract="JLSoapCommon.IJLSoapResponse" />
\par </service>
\par </services>
\par <bindings>
\par <basicHttpBinding>
\par <binding name="SoapRspBindingBasicHttp"
\par maxReceivedMessageSize="65536">
\par <readerQuotas maxStringContentLength="65536"/>
\par <security mode="None">
\par <transport clientCredentialType="None" />
\par </security>
