According to this article description custom-membership-provider-with-repository-injection

I implement the custom Membership provide with inject.

Answer 1

The result is always null. why? because asp.net has it's own static property for membership.

which is membership.provider. and this instance is not part of instance ninject management.

to workaround it , you need to use kernel.inject . but on the generate aspnetmvc.cs you would see that it's injection on PreApplicationStart event and won't let you.

here is the soloution by cipto that solve the problem for me. add this to your NinjectWebCommon

    [assembly: WebActivator.PreApplicationStartMethod(typeof(TopRankFantasy.App_Start.NinjectMVC3), "Start")]
    [assembly: WebActivator.PostApplicationStartMethod(typeof(TopRankFantasy.App_Start.NinjectMVC3), "RegisterMembership")]
    [assembly: WebActivator.ApplicationShutdownMethodAttribute(typeof(TopRankFantasy.App_Start.NinjectMVC3), "Stop")]

    public static void RegisterMembership()
    {
        bootstrapper.Kernel.Inject(Membership.Provider);
    }

Answer 2

Since a custom RoleProvider often comes along with the custom MembershipProvider, in that case it is useful to add an injection for the Role Provider class. I used the ramon22's solution with an additional line.

[assembly: WebActivator.PreApplicationStartMethod(typeof(TopRankFantasy.App_Start.NinjectMVC3), "Start")]
[assembly: WebActivator.PostApplicationStartMethod(typeof(TopRankFantasy.App_Start.NinjectMVC3), "RegisterMembership")]
[assembly: WebActivator.ApplicationShutdownMethodAttribute(typeof(TopRankFantasy.App_Start.NinjectMVC3), "Stop")]

public static void RegisterMembership()
{
    bootstrapper.Kernel.Inject(Membership.Provider);
    bootstrapper.Kernel.Inject(Roles.Provider);
}

I had a lot of trouble trying this and ended up adding a method that gets me a repository

using System.Web.Mvc;  //Used to access dependency resolver

    private IUserRepository GetUserRepository()
    {
        return DependencyResolver.Current.GetService<IUserRepository>();
    }

I then call this in the methods that require it

I was able to get the repository to become injected using constructor injection but as soon as I went to use the repository the object had been disposed. I found the above to be the simplest alternative.

However, I guess you could also use the Initialize() method

    IUserRepository userRepository;
    public override void Initialize(string name, NameValueCollection config)
    {
        base.Initialize(name, config);
        this.userRepository = DependencyResolver.Current.GetService<IUserRepository>();
    }

Or another way would be to use a property

public IUserRepository UserRepository
{
    get
    {
        return DependencyResolver.Current.GetService<IUserRepository>();
    }
}
