WCF Self Host problem in setup.

WCF Self Host problem in setup.

I'm setting up a service to run the server for a WCF rather then IIS, and have my server app:

static void Main()

{

ServiceHostm myServicHost = new ServiceHost(

typeof(WcfPortal),

new Uri("net.tcp://localhost:8001"));

myServicHost.Open();

Application.Run(new Form1());

myServicHost.Close();

}

the referces added are my library of BOs and CSLA

and my app config is:

<configuration>

<system.serviceModel>

<services>

<service name = "WcfPortal">

<endpoint

address = "net.tcp://localhost:8001"

binding = "netTcpBinding"

contract = "Csla.Server.Hosts.IWcfPortal"

/>

</service>

</services>

</system.serviceModel>

</configuration>

I'm getting "Service 'Csla.Server.Hosts.WcfPortal' has zero application (non-infrastructure) endpoints."

I feel I'm missing something, such as net.tcp://localhostL8001/????? but not sure what.

The http version I've got wors well, but is slow, as based on my own nonCSLA testing WCF where you can use netTCP appears to be 5times faster.....

Thanks Tony

Hi,

Yes, you're missing the endpoint name. The correct address is a valid URI like this: net.tcp://localhost:8001/MyWcfService

Just make this change in the URI and address in the configuration file and should be fine...

 

Regards,

Thanks - I see the interface is the key here, not the uri, as long as both the client/server have the same url referece? OK... so  I've got past this error now, but when I call the DataPortal (in this case to setup my security):

"The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://ws.lhotka.net/WcfDataPortal:FetchResult. The InnerException message was ''Element' '_fieldManager' from namespace 'http://schemas.datacontract.org/2004/07/Csla' is not expected. Expecting element '_serializableChangedHandlers'.'.  Please see InnerException for more details."

I'm thinking as both the client and server is using the same interface, the the 'joy' of WCF means tha the pmumbing is automatic (as long as the interface IS the same)........ mmmm - Ah!

I re-added references to CSLA, and bingo!! I'm away... thanks for pointing out the obvious - wcf light has just gone on! (I'm so used to the webservce,iis,soap stuff).

Thanks Tony

I'm also trying to get this to work with netTcpBinding with a console app as my host:

Here's my config:

<system.serviceModel>

      <services>

        <service name="Csla.Server.Hosts.WcfPortal">

          <endpoint address="net.tcp://localhost:7001/WcfPortal" binding="netTcpBinding"

            bindingConfiguration="" contract="Csla.Server.Hosts.IWcfPortal" />

        </service>

      </services>

    </system.serviceModel>

 

Here's my hosting code:

Dim host As New ServiceModel.ServiceHost(GetType(Csla.Server.Hosts.WcfPortal))

            host.Open()

            For Each ep In host.Description.Endpoints

                Console.WriteLine(ep.Address)

            Next

            Console.WriteLine("The service is hosted. Press any key to exit")

I can see the endpoint listed in the console.  When I try to add a service reference to the net.tcp://localhost:7001/WcfPortal address, I get this error:
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:7001/WcfPortal'.
The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:04:59.8099892'.
An existing connection was forcibly closed by the remote host
If the service is defined in the current solution, try building the solution and adding the service reference again.
Any pointers please?

Resolved it with the following serviceModel config:

<services>

      <service behaviorConfiguration="returnFaults" name="Csla.Server.Hosts.WcfPortal">

        <host>

          <baseAddresses>

            <add baseAddress="net.tcp://localhost:7001/WCFDataPortal"/>

          </baseAddresses>

        </host>

        <endpoint binding="netTcpBinding"

                  bindingConfiguration="netTcpBinding_IWcfPortal"

                  contract="Csla.Server.Hosts.IWcfPortal" />

        <endpoint address="mex" binding="netTcpBinding" contract="IMetadataExchange"

           bindingConfiguration="mexTcp" />

      </service>

    </services>

    <behaviors>

      <serviceBehaviors>

        <behavior name="returnFaults">

          <serviceDebug includeExceptionDetailInFaults="true"/>

          <serviceMetadata />

        </behavior>

      </serviceBehaviors>

    </behaviors>

    <bindings>

      <netTcpBinding>

        <binding name="netTcpBinding_IWcfPortal" maxReceivedMessageSize="2147483647" portSharingEnabled="true">

          <readerQuotas maxDepth="1024" maxStringContentLength="2147483647"

            maxArrayLength="2147483647" maxBytesPerRead="2147483647" />

          <security mode="None" />

        </binding>

        <binding name="mexTcp" portSharingEnabled="true">

          <security mode="None" />

        </binding>

      </netTcpBinding>

    </bindings>
