Ninject, Bind should be .InRequestScope() OR .InSingletonScope()

Question

I have Below code One is bindable to my User Repository and another for Cache. What scope should I use for UserRepository and Cache. Should Scope on UserRepository be Singleton?

    this.Bind<IUserRepository>().To<UserRepositary>().InRequestScope();

    this.Bind<IDistributedCacheService>().To<DistributedCacheService>().InSingletonScope();

Answer 1

Usually the repositories are bound inrequestscope because that generally defines the unit of work or database transaction size.

Update: Here is a bit more information on managing critical resources using ninject. I ran into this while binding my repos inrequestscope.
