类型RoleStore< IdentityRole& gt;不能分配给服务IRoleStore< IRole& gt;

问题描述

我正在尝试使用Autofac为使用MVC5和EF6的项目设置依赖项注入.

I'm trying to set up dependency injection with Autofac for project using MVC5 and EF6.

我很难弄清楚如何正确解耦EntityFramework.RoleStore< EntityFramework.IdentityRole>.实施.
我只想依赖Identity.IRoleStore< Identity.IRole>但是我知道对于泛型类，我需要指定具体的实现，而不是接口.

I'm having a hard time figuring out how to decouple correctly the EntityFramework.RoleStore<EntityFramework.IdentityRole> implementation.
I would like have dependency only on Identity.IRoleStore<Identity.IRole> but I'm aware that for generic classes I need to specify the concrete implementation, not the interface.

这是我尝试过的:

        builder.RegisterType<IdentityRole>().As<IRole>();
        builder.RegisterType<RoleManager<IRole>>();
        builder.RegisterType<RoleStore<IdentityRole>>().As<IRoleStore<IRole>>();
        builder.Register(c => new RoleManager<IRole>(c.Resolve<IRoleStore<IRole>>()));

推荐答案

参加聚会有点晚，但是这对Autofac来说对我有用:

Bit late to the party but this worked for me with Autofac:

builder.RegisterType<RoleStore<IdentityRole>>().As<IRoleStore<IdentityRole, string>>();

我的完整模块供参考:

builder.RegisterType<UserStore<ApplicationUser>>().As<IUserStore<ApplicationUser>>();
builder.RegisterType<RoleStore<IdentityRole>>().As<IRoleStore<IdentityRole, string>>();
builder.RegisterType<ApplicationUserManager>();
builder.RegisterType<ApplicationRoleManager>();

我正在为UserManager和RoleManager使用包装器

I'm using wrappers for the UserManager and RoleManager

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store)
        : base(store)
    {
    }
}

public class ApplicationRoleManager : RoleManager<IdentityRole>
{
    public ApplicationRoleManager(IRoleStore<IdentityRole, string> roleStore)
        : base(roleStore)
    {
    }
}
