Question

我要做的是以下内容：

使用Identity Core设置登录/注销，主键为Int。我按照ASP.NET核心文档中的以下文章：Configure Identity primary keys data type。（他们使用GUID，但想法是一样的）。设置非常成功，ID是整数，数据库正在填充。

但是，当我尝试使用内置SignInManager<ApplicationUser>登录并调用方法时

var result = await _signInManager.PasswordSignInAsync(Username,Password, RememberMe, lockoutOnFailure: false);

我收到以下错误：

System.ArgumentNullException：值不能为null。参数名称：值

我确定SecurityTimeStamp已填满，并且服务已添加到Startup.cs中

services.AddIdentity<ApplicationUser, ApplicationRole>()
            .AddEntityFrameworkStores<ApplicationDbContext, int>()
            .AddDefaultTokenProviders();

我的课程：

ApplicationUser

public class ApplicationUser : IdentityUser<int>
{
}

ApplicationRole

public class ApplicationRole : IdentityRole<int>
{
}

ApplicationDbContext

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, int>
        {
            public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
                : base(options)
            {
            }
    }

Answer 1

删除并重新创建数据库......非常明显。

//解决。

Answer 2

3年后，我坚持了这个问题。重新创建数据库没有帮助。我已经将PK从string更改为int，并且UserManager已经成功创建了记录，但是SignInManager却没有成功登录新记录创建的用户具有相同的错误。

解决方案：

我发现仅在创建角色时向用户提供角色即可解决问题。

await userManager.AddToRoleAsync(user, UserRoles.Basic.ToString());

身份核心主键作为Int无法使用SignInManager
