c# - AutoMapper 4.2 and Ninject 3.2 -

i'm updating project of mine use automapper 4.2, , i'm running breaking changes. while seem have resolved said changes, i'm not entirely convinced i've done in appropriate way.

in old code, have ninjectconfiguration, , automapperconfiguration class each loaded webactivator. in new version automapperconfiguration drops out , instead instance mapperconfiguration directly in ninjectconfiguration class bindings happening, so:

private static void registerservices(     ikernel kernel) {     var profiles = assemblyhelper.gettypesinheriting<profile>(assembly.load("???.mappings")).select(activator.createinstance).cast<profile>();     var config = new mapperconfiguration(         c => {             foreach (var profile in profiles) {                 c.addprofile(profile);             }         });      kernel.bind<mapperconfiguration>().tomethod(         c =>             config).insingletonscope();      kernel.bind<imapper>().tomethod(         c =>             config.createmapper()).inrequestscope();      registermodules(kernel); } 

so, appropriate way of binding automapper 4.2 using ninject? seems working far, want make sure.

in before imapper interface didn't existed in library had implement interface , class below , bound them singleton pattern.

public interface imapper {     t map<t>(object objecttomap); }  public class automapperadapter : imapper {     public t map<t>(object objecttomap)     {         //mapper.map static method of library!         return mapper.map<t>(objecttomap);     } } 

now bind library's imapper interface single instance of mapperconfiguration.createmapper()

the problem code tho, should use single instance(or ninject says, constant) bind.

// reminder var config = new mapperconfiguration(     c => {         foreach (var profile in profiles) {             c.addprofile(profile);         }     }); // solution starts here var mapper = config.createmapper(); kernel.bind<imapper>().toconstant(mapper);
