Question
I have this App.config in my wcf service library:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="addr" value="net.tcp://localhost:22222/AdministrationService/"/>
</appSettings>
<system.serviceModel>
<services>
<service name="Watchman.WcfService.AdministrationService" behaviorConfiguration="MyBehavior">
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:22222/AdministrationService/"/>
</baseAddresses>
</host>
<endpoint name="Ep1" address="net.tcp://localhost/AdministrationService/" binding="netTcpBinding" bindingConfiguration="DuplexBinding" contract="Watchman.WcfService.Interfaces.IAdministration"/>
<endpoint name="mex" address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MyBehavior">
<serviceThrottling maxConcurrentSessions="10000"/>
<serviceMetadata httpGetEnabled="true" httpGetUrl="http://localhost/AdministrationService/Ep1/wsdl"/>
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<netTcpBinding>
<binding name="DuplexBinding" sendTimeout="00:00:01">
<reliableSession enabled="true"/>
<security mode="None"/>
</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client"/>
</startup>
</configuration>
but I got error:
"The Address property on ChannelFactory.Endpoint was null. The ChannelFactory's Endpoint must have a valid Address specified."
It seems like application doesn't this tcp.net endpoint. Why?
Solution 3
I just noticed that svcutil generates bad endpoint in wcf client project. There's
<endpoint binding="basicHttpBinding"
bindingConfiguration="DefaultBinding_IAdministration"
contract="IAdministration"
name="DefaultBinding_IAdministration_IAdministration" />"
instead of my net.tcp
endpoint.
I also observed that's because of generation of ProxyFile.cs
and App.config
from
svcutil WcfServiceLibrary.dll
If I generate this files from metadata like:
svcutil net.tcp://localhost:8080/AdministrationService/mex /language:C# /out:ProxyFile.cs /config:App.config
then it works fine (in App config is described correct net.tcp endpoint)
Does anyone knows why cooperation svcutil with *.dll goes wrong?
OTHER TIPS
I have this App.config in my wcf service library
You cannot have an app.config in a wcf class library and expect WCF to read settings from it. It doesn't make sense. Config files such as app.config are defined in the final executable application project (such as a Console application, WinForms, WPF, ...). Or if it is a web application you use a web.config. But there is not such thing as app.config for a class library. So you might need to include this WCF configuration in the app/web.config of the application using your class library.
You have specified a base address for net.tcp, so the address on the net.tcp endpoint becomes a relative address. So, effectively the address of the end point becomes net.tcp://localhost:22222/AdministrationService/localhost/AdministrationService/.
Change the address on the endpoint to a relative address and re-generate the proxy class using svcutil.
