通过DLL从Windows服务调用WCF服务

Question

Basically my situation is this:

Windows Service --Calls--> MethodinDLL --Calls--> WCFService.

Service configuration is written on the DLL side manually, and on windows service side in config - I am insterested if WCF parameters on DLL side and on the Windows service side should match. More elaboration below.

I will tell you my setup. I call WCF Service from DLL. There is code inside DLL which calls WCF service such as this:

//Inside DLL
BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None);
EndpointAddress epa = new EndpointAddress("http://localhost:16593/FreeSpaceDatabase.svc");

YourServiceClient proxy = new YourServiceClient(binding, epa);

I manually provide parameters as you can see.

Now, I have a windows service which actually refers to this DLL, and using DLL (or via DLL), calls the WCF Service. (The call to WCF Service is located in DLL - windows service doesn't have method to call WCF Service).

But I was forced to still add this on the Windows service side:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IFreeSpaceDatabase" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:16593/FreeSpaceDatabase.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IFreeSpaceDatabase"
                contract="ServiceReference1.IFreeSpaceDatabase" name="BasicHttpBinding_IFreeSpaceDatabase" />
        </client>
    </system.serviceModel>
</configuration>

My question is what if the EndpointAddress("http://localhost:16593/FreeSpaceDatabase.svc") which I specify in the code on the DLL side (like in the beginning of my question):

  EndpointAddress epa = new EndpointAddress("http://localhost:16593/FreeSpaceDatabase.svc");

is different from the endpoint address specified in the AppConfig file as of the Windows service ? Is it allowed? Or they should always be the same?

Answer 1

You can remove this address from your config and it should work. I have these settings (bindings and endpoints) in my code and only this in my config:

<system.serviceModel>
    <bindings />
    <client />
</system.serviceModel>
