c# - Asp.Net SignalR DependencyResolver not resolving hubs -

we have complex application hubs spread accross multiple dlls. complete application uses di lightcore. face problem signalr doesn't seem use dependencyresolver adapter have written.

we have tried 2 different ways inject our custom idependencyresolver:

globalhost.dependencyresolver = new lightcoresignalrdependencyresolver(); 

and

var hc = new hubconfiguration(resolver = new lightcoresignalrdependencyresolver());  app.mapsignalr(hc); 

in both cases, our resolver not called when hub created. worse, exceptions there no parameterless constructor hubs.

we did short test injecting custom ihubactivator defaultdependencyresolver. same result. hubactivator not used @ - @ least not run our breakpoints , log entries.

does have idea go wrong here?

(in mvc , webapi custom dependency resolvers work expected)

hubs register using builder helper:

builder.register<hubs.logginghub, hubs.logginghub>();

the dependency resolver looks this:

public class lightcoresignalrdependencyresolver : defaultdependencyresolver {     private readonly icontainer _container;      public lightcoresignalrdependencyresolver(icontainer container)     {         if (container == null) throw new argumentnullexception("container");         _container = container;     }      public object getservice(type servicetype)     {         try         {             return _container.resolve(servicetype);         }         // idependencyresolver implementations must not throw exception          // return null if type not registered         catch (registrationnotfoundexception registrationnotfoundexception)         {             return base.getservice(servicetype);         }     }      public ienumerable<object> getservices(type servicetype)     {         try         {             return  _container.resolveall(servicetype).concat(base.getservices(servicetype));         }         // idependencyresolver implementations must not throw exception          // return empty object collection if type not registered         catch (registrationnotfoundexception registrationnotfoundexception)         {             return base.getservices(servicetype);         }     } } 

hub constructors this:

this 1 used default resolver , uses our internal bootstrapper resolve dependencies. (the ugly working way - showing dependencies can resolved)

    public robotcontrolhub()     {         _publisher = booty.container.resolve<ipublisher>();         _messageservice = booty.container.resolve<irobotmessagerepectionservice>();         _commandsservice = booty.container.resolve<irobotgenericcommandsservice>();         _connectionsmapping = booty.container.resolve<irobotconnectionmappingrepository>();     } 

thats constructor expect called when using our resolver within signalr.

    public robotcontrolhub(         irobotconnectionmappingrepository connectionsmapping,          irobotgenericcommandsservice commandsservice,         irobotmessagerepectionservice messageservice,         ipublisher publisher)     {         _publisher = publisher;         _messageservice = messageservice;         _commandsservice = commandsservice;         _connectionsmapping = connectionsmapping;     } 

but said, seems not called.

sometimes it's sleep night , forget issue. next morning @ code , see there "override" missing. correct code:

public class lightcoresignalrdependencyresolver : defaultdependencyresolver {     private readonly icontainer _container;      public lightcoresignalrdependencyresolver(icontainer container)     {         if (container == null) throw new argumentnullexception("container");         _container = container;     }      public **override** object getservice(type servicetype)     {         try         {             return _container.resolve(servicetype);         }         // idependencyresolver implementations must not throw exception          // return null if type not registered         catch (registrationnotfoundexception registrationnotfoundexception)         {             return base.getservice(servicetype);         }     }      public **override** ienumerable<object> getservices(type servicetype)     {         try         {             return  _container.resolveall(servicetype).concat(base.getservices(servicetype));         }         // idependencyresolver implementations must not throw exception          // return empty object collection if type not registered         catch (registrationnotfoundexception registrationnotfoundexception)         {             return base.getservices(servicetype);         }     } }
