Question

I am trying to host a WCF service with netNamedPipeBinding in a web applicaion on a Vista machine.

I enabled the non-HTTP service activation as described in this article: http://msdn.microsoft.com/en-us/library/ms731053.aspx

I configured the service as follows:

<endpoint address="net.pipe://myservice"
binding="netNamedPipeBinding"
bindingConfiguration="MyService_NamedPipeBindingConfig"
contract="ICMyService" />

<netNamedPipeBinding>
    <binding name="MyService_NamedPipeBindingConfig"
         maxBufferSize="2147483647"
         maxReceivedMessageSize="2147483647">
        <security mode="None">
            <transport protectionLevel="None" />
        </security>
    </binding>
</netNamedPipeBinding>

When I browse to the .svc file (on IIS, not the Visual studio webserver) I get this message:

[InvalidOperationException: The protocol 'net.pipe' is not supported.]
   System.ServiceModel.Activation.HostedTransportConfigurationManager.InternalGetConfiguration(String scheme) [phone]

   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +68
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

I was hoping for a quicker and easier deployment using WAS, but this exception is not helping. Does any body know if I am doing somehting wrong?

Did you follow that article exactly, or did you replace instances of ‘net.tcp’ in the command lines with ‘net.pipe’? It may just be that you did not enable the net.pipe binding for that web site and your virtual directory.
