IIS Hosting中的WCF库未从客户端连接

Question

Hello I have a WCF service library project and I have created a WPF app to host it for testing and that works just fine, but I also created a web app to host it in IIS for production and when I try to connect to the IIs one I never can.

I am using a net.tcp bininding and I have gone in to IIS and added the net.tcp biniding to the web app and the web site.

Basically this is a duplex service with the methods marked as one way. When I call the method in the client the callback never gets called and I end up just sitting there waiting for several minutes before I close the application. When I self host the service I get a response almost immediately on the callback.

Also I have tried using localhost:808 and just localhost. If I use svcutil to generate the config it leaves the port off of the address. I don't get any errors that I am aware of, but I honestly don't really know how to tell if I get any errors it throws from IIS.

Also if I go to http://localhost:9595/EcuWebService/Service.svc I get the page that tells me to use svcutil to generate my client proxy.

As Jocke suggested below I attached a debugger and received this error: The service '/EcuWebService/service' does not exist.

Also here is the contents of my svc file:

<%@ ServiceHost Language="C#" Debug="true" Service="EcuWeb.ServiceLib.Contracts.EcuWebServiceMain" %>

below is my Web.config:

This is the config for the client app. The commented out endpoint is the endpoint that I use when not hosting in IIS and it works.

Answer 1

Ok I finally got this figured out.

First I had to add:

<host>
 <baseAddresses>
  <add baseAddress="net.tcp://localhost:5555/EcuWebService" />
  <add baseAddress="http://localhost/EcuWebService" />
 </baseAddresses>
</host>

Then for the endpoint I just used:

<service name="EcuWeb.ServiceLib.Contracts.EcuWebServiceMain">
<endpoint address="service" binding="netTcpBinding" bindingConfiguration=""
 name="netTcp_EcuWebServiceEndpoint" contract="EcuWeb.ServiceLib.Contracts.IEcuWebServiceMain">
 <identity>
  <dns value="localhost" />
 </identity>
</endpoint>

Then in the client I had to use:

<endpoint address="net.tcp://localhost/EcuWebService/Service.svc/service"
    binding="netTcpBinding" bindingConfiguration="netTcp_EcuWebServiceEndpoint"
    contract="EcuWebService.IEcuWebServiceMain" name="netTcp_EcuWebServiceEndpoint">
            <identity>
                <dns value="localhost" />
            </identity>
        </endpoint>

When I added the port it didn't work, but once I removed it it worked no problem. Also I doubt the base address is required as IIS is giving the address anyway.

Answer 2

What happens? Do you get an exception? Can you browse it in the IIS?

Your service has:

endpoint address="net.tcp://localhost:808/EcuWebService/mex"

and the client:

endpoint address="net.tcp://localhost/EcuWebService/service"

I think you need provide more details to get a good answer.
