asp.net web api - WebApi 2 -cant determined DataProtection.IDataProtector Dependency Injection with structuremap -

i'm using this beriliant project base of mvc project. when use webapi project there problem in idataprotector injection. redesign base , upload here, , add console project testing authorizing webapi.

this structuremap initialization :

            private static readonly lazy<container> _containerbuilder =         new lazy<container>(initstructuremap, lazythreadsafetymode.executionandpublication);      public static icontainer container     {         { return _containerbuilder.value; }     } return new container(ioc =>         {             ioc.for<iunitofwork>().hybridhttporthreadlocalscoped().use(() => new dbcontext());              ioc.for<idataserializer<authenticationticket>>().use<ticketserializer>();             ioc.for<isecuredataformat<authenticationticket>>().use<securedataformat<authenticationticket>>();          }); 

and in webapiconfig class di this:

            var container = structuremapmvc.container;         globalconfiguration.configuration.services.replace(             typeof(ihttpcontrolleractivator), new  structuremaphttpcontrolleractivator(container)); 

in startup create dataprotector iappbuilder :

        public void configureauth(iappbuilder app)     {         structuremapmvc.container.configure(config =>         {             config.for<idataprotectionprovider>()                   .hybridhttporthreadlocalscoped()                   .use(() => app.getdataprotectionprovider());         });      } 

it start after webapiconfig , idataprotection not work in webapi. servicelayer in separate project , dataprotection need inject there.

you need add 2 class project :

1-structuremapdependencyscope class

using structuremap; using system; using system.collections.generic; using system.linq; using system.web.http.dependencies;  namespace project.helpers {     public class structuremapdependencyscope : idependencyscope     {         protected readonly icontainer container;          public structuremapdependencyscope(icontainer container)         {             if (container == null)             {                 throw new argumentnullexception("container");             }              this.container = container;         }          public void dispose()         {             this.container.dispose();         }          public object getservice(type servicetype)         {             if (servicetype == null)             {                 return null;             }              try             {                 return servicetype.isabstract || servicetype.isinterface                            ? this.container.trygetinstance(servicetype)                            : this.container.getinstance(servicetype);             }             catch             {                 return null;             }         }          public ienumerable<object> getservices(type servicetype)         {             return this.container.getallinstances(servicetype).cast<object>();         }     } } 

2-structuremapdependencyresolver class

using structuremap; using system.web.http.dependencies;  namespace project.helpers {     public class structuremapdependencyresolver : structuremapdependencyscope, idependencyresolver     {         public structuremapdependencyresolver(icontainer container)             : base(container)         {         }         public idependencyscope beginscope()         {             icontainer child = this.container.getnestedcontainer();             return new structuremapdependencyresolver(child);         }     } } 

at end replace code yours in webapiconfig class:

// ioc config var container = smobjectfactory.container;  // web api configuration , services config.dependencyresolver = new structuremapdependencyresolver(container);
