wcf - Injecting dependencies into an IErrorHandler implementation -

i implementing ierrorhandler in order centralize of error handling wcf service in 1 place. works well:

public class serviceerrorhandler : ierrorhandler {      public bool handleerror(exception error)     {         // ..log..     }      public void providefault(exception error, messageversion version, ref message fault)     {         // ..provide fault..     }  } 

now, we're using ninject inject dependencies in rest of service, , i'd same here. since wcf constructing objects based on configuration, , don't think have hooks process, need use property injection:

    [inject]     public iloggingservice logger { get; set; } 

however, never seems injected. tried using ninject's mvc extensions set serviceerrorhandler allow injection filter, didn't seem trick. there way make happen?

late answer, can inject dependencies ierrorhandler creating custom servicehost, let's testservicehost.

in testservicehost need do:

1. implement constructor ierrorhandler parameter.
2. inside, create private nested class named errorhandlerbehaviour*, needs implement both iservicebehavior , ierrorhandler. must have constructor ierrorhandler parameter.
3. override onstarting() method, add errorhandlerbehaviour service behaviours. behaviours must added before base.onstarting().

*the idea came juval lowy's example in book - "programming wcf services". more information faults , error extensions can find there.

here working host console application. don't use ioc there, pure di, can resolve logger ioc want:

using system; using system.collections.objectmodel; using system.servicemodel; using system.servicemodel.channels; using system.servicemodel.description; using system.servicemodel.dispatcher;  namespace consolehost {     class program     {         static void main(string[] args)         {             var logger = new dummylogger();             var errorhandler = new testerrorhandler(logger);              servicehost host = new testservicehost(errorhandler, typeof(testservice), new uri("net.tcp://localhost:8002"));             host.open();              console.writeline("press enter exit");             console.readkey();         }     }      [servicecontract]     public interface itestservice     {         [operationcontract]         string test(int input);     }      public class testservice : itestservice     {         public string test(int input)         {             throw new exception("test exception!");         }     }      public class testerrorhandler : ierrorhandler     {         private ilogger logger { get; }          public testerrorhandler(ilogger logger)         {             logger = logger;         }          public bool handleerror(exception error)         {             logger.log(error.message);             return true;         }          public void providefault(exception error, messageversion version, ref message fault)         {             faultexception fe = new faultexception();             messagefault message = fe.createmessagefault();             fault = message.createmessage(version, message, null);         }     }      public class testservicehost : servicehost     {         private readonly ierrorhandler errorhandler;          public testservicehost(ierrorhandler errorhandler, type servicetype, params uri[] baseaddresses)             : base(servicetype, baseaddresses)         {             this.errorhandler = errorhandler;         }          protected override void onopening()         {             description.behaviors.add(new errorhandlerbehaviour(errorhandler));             base.onopening();         }          class errorhandlerbehaviour : iservicebehavior, ierrorhandler         {             private readonly ierrorhandler errorhandler;              public errorhandlerbehaviour(ierrorhandler errorhandler)             {                 this.errorhandler = errorhandler;             }              bool ierrorhandler.handleerror(exception error)             {                 return errorhandler.handleerror(error);             }              void ierrorhandler.providefault(exception error, messageversion version, ref message fault)             {                 errorhandler.providefault(error, version, ref fault);             }              void iservicebehavior.applydispatchbehavior(servicedescription servicedescription, servicehostbase servicehostbase)             {                 foreach (channeldispatcher channeldispatcher in servicehostbase.channeldispatchers)                 {                     channeldispatcher.errorhandlers.add(this);                 }             }              void iservicebehavior.addbindingparameters(servicedescription servicedescription, servicehostbase servicehostbase, collection<serviceendpoint> endpoints, bindingparametercollection bindingparameters)             {             }              void iservicebehavior.validate(servicedescription servicedescription, servicehostbase servicehostbase)             {             }         }     }      // dummy logger     public interface ilogger     {         void log(string input);     }      public class dummylogger : ilogger     {         public void log(string input) => console.writeline(input);     } } 

and configuration:

<system.servicemodel>   <services>     <service name="consolehost.testservice">       <endpoint address="net.tcp://localhost:8002/testservice"                 binding="nettcpbinding"                 contract="consolehost.itestservice" />     </service>   </services> </system.servicemodel> 

btw. make sure added system.runtime.serialization references
