c# - Configure Ninject Factory to return the same instance every time -

i have service layer reusing (aka business layer).

here's example of 1 of services imycontextfactory dependency, returns instance of imycontext.

public class myservice : imyservice  {     private imycontextfactory dbcontextfactory;      public myservice(imycontextfactory dbcontextfactory)     {         this.dbcontextfactory = dbcontextfactory;     }      public dosomething(int id)     {         // instance of db use         imycontext dbcontext = this.dbcontextfactory.createmydbcontext();          // use business layer         var user = dbcontext.set<user>().find(id);     } } 

i using ninject factory extension.

is possible make imycontextfactory return same instance of imycontext every time?

background

originally injecting imydbcontext straight service without factory , had inrequestscope() when initialized asp.net mvc website.

but making use of service in windows service , don't want dbcontext become bloated because of frequent looping. didn't want service newed every request either, that's why thought factory within service trick.

i need best of inrequestscope() , new instance every time depending on configuration. have separate config asp.net , windows service - it's how singleton each time factory.

i'm not proficient ninject, according page https://github.com/ninject/ninject.extensions.factory/wiki/factory-interface seems instance returned factory retrieved iresolutionroot.

my take have register imycontext concrete type singleton lifetime type.

(but seems it's not of idea not destroy context, according erik fukenbusch's comment)
