Question

我有一个MVC5项目，我一直在关注本教程：

http://www.asp.net/identity/overview/extensibility/overview-of-custom-storage-providers-for-aspnet-identity

基本上我想使用自己的数据库，而不是使用代码优先的默认方法。我已经完成了所有自定义Store和Identity，但我不知道如何更改我的应用程序以使用我的自定义Context，因为MVC5项目的默认代码使用代码优先行为。

我也对IdentityModels.cs中的代码和Startup中的CreatePerOwinContext感到困惑。有人可以向我解释这个或者给我一个101教程的链接吗？我试过环聊互联网，但我仍然找不到合适的文档/分步教程。

我的自定义UserStore：

public class UserStore : IUserStore<IdentityUser, int>
{
    public UserStore() { ... }
    public UserStore(MySQLDatabase database) { ... }
    public Task CreateAsync(IdentityUser user) { ... }
    public Task DeleteAsync(IdentityUser user) { ... }
    public Task<IdentityUser> FindByIdAsync(int userId) { ... }
    public Task<IdentityUser> FindByNameAsync(string userName) { ... }
    public Task UpdateAsync(IdentityUser user) { ... }
    public void Dispose() { ... }
}

我的自定义IdentityUser：

public class IdentityUser : IUser<int>
{
    public IdentityUser() { ... }
    public IdentityUser(string userName) { ... }
    public int Id { get; set; }
    public string UserName { get; set; }
}

IdentityModels.cs默认代码：

public class ApplicationUser : IdentityUser
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

启动：

public void ConfigureAuth(IAppBuilder app)
        {
            app.CreatePerOwinContext(ApplicationDbContext.Create);
            app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
            app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Account/Login"),
                Provider = new CookieAuthenticationProvider
                { 
                    OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
                        validateInterval: TimeSpan.FromMinutes(30),
                        regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
                }
            });            
            app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
            app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));
            app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
}

任何帮助将不胜感激。
