Hi,

I’m having great difficulty getting a simple net.tcp,n-tier deployment working on IIS.

 What I have done:

·        IIS 7.0 is installed & the “WindowsCommunication Foundation Non-HTTP Activation” feature is enabled.

·        Windows Process Activation, Net.Tcp Port Sharing& Net.Tcp Listener Adapter Services are Automatic & started.

·        For IIS in the “Site Bindings” I have setnet.tcp to 12345:* and for the BOS Web Application I have set “EnabledProtocols” to http,net.tcp

·        The Application Pool is .NET 4, Integrated

 I have successfully implemented a standard WCF DuplexService over TCP so I’m pretty sure all of this is setup correctly.

The Web.Config contains the following:

 <ideablade.configuration version="6.00" xmlns="http://schemas.ideablade.com/2010/IdeaBladeConfig">

    <logging logFile="log\DebugLog.xml" />

  </ideablade.configuration>

  <system.serviceModel>

    <services>

      <service name="EntityService" >

        <endpoint address=""

                  binding="netTcpBinding" 

                  bindingConfiguration="InsecureTcp"

                  contract="IdeaBlade.EntityModel.IEntityServiceContract" />

      </service>

      <service name="EntityServer">

        <endpoint address=""    

                  binding="netTcpBinding"

                  bindingConfiguration="InsecureTcp"

                  contract="IdeaBlade.EntityModel.IEntityServerContract" />   

      </service>

    </services>     

    <bindings>

      <netTcpBinding>

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

          <security mode="None"/>

        </binding>

      </netTcpBinding>

    </bindings>   

  </system.serviceModel>

 And the App.Config:

  <ideablade.configuration version="6.00" xmlns="http://schemas.ideablade.com/2010/IdeaBladeConfig">

    <logging logFile="DebugLog.xml"/>    

    <objectServer>

      <clientSettings isDistributed="true" />

    </objectServer>   

  </ideablade.configuration> 

  <system.serviceModel>

    <client>

      <endpoint name="EntityService"

                address="net.tcp://localhost:12345/WpfApplication1Web/EntityService.svc"

                binding="netTcpBinding" 

                bindingConfiguration="BasicTcp"

                contract="IdeaBlade.EntityModel.IEntityServiceContract"/>

      <endpoint name="EntityServer"

                address="net.tcp://localhost:12345/WpfApplication1Web/EntityServer.svc"

                binding="netTcpBinding" 

                bindingConfiguration="BasicTcp"

                contract="IdeaBlade.EntityModel.IEntityServerContract"/>

    </client> 

    <bindings>

      <netTcpBinding>

        <binding name="BasicTcp">

          <security mode="None" />

        </binding>

      </netTcpBinding>

    </bindings>    

  </system.serviceModel> 

When I run the application I get the following error: Cannotfind ObjectServer or default ServiceKey

When looking in the Client log file there is this message:

There was no endpoint listening at net.tcp://localhost:12345/WpfApplication1Web/EntityService.svcthat could accept the message. This is often caused by an incorrect address orSOAP action. See InnerException, if present, for more details.

The weird thing is that if I open the EntityService ina web browser (http://localhost/WpfApplication1Web/EntityService.svc )and then run the application, everything works. Itseems to me that the Activation of the TCP endpoint is not working unless thehttp endpoint is activated first.

Another option I tried was to explicitly create the EntityServer.svc& EntityService.svc file and comment out the RegisterVirtualPathProvider inthe Global.asax.

When running the application I get the same error as above,but in the Event View there is this:

WebHost failed to process a request.

I’m all out of ideas, any help will be greatly appreciated.

Alternatively, can I get hold a working wpf sample applicationfor an n-tier, net.tcp configuration?

I'm using Devforce 6.1.1.1 for a WPF application
