ASP.NET标识：在类库项目

Question

我希望将ASP.NET标识移植到我的业务逻辑中，而不是在API级别上使用它。我创建了两个数据库上下文，它们是dbcontext和identitycontext来处理这个问题，因为我使用单个数据库来识别身份表和其他实体。问题是我想在我的BLL中使用单个上下文但它不能正常工作。我还尝试创建dbcontext和identitydbcontext，但只有dbcontext将数据提交到数据库表中，而identitydbcontext无法将数据提交到我的单个数据库中的标识表中。有没有人有解决方案如何在我的BLL类库项目中使用单个数据库上下文提交数据，并使用entityframework逆向工程生成DAL中的模型？

数据访问层 1.实体框架逆向工程生成的上下文类

public partial class TwiksDbContext : IdentityDbContext
{
    static TwiksDbContext()
    {
        Database.SetInitializer<TwiksDbContext>(null);
    }

    public TwiksDbContext()
        : base("Name=TwiksDbContext")
    {
    }

    public DbSet<AspNetRole> AspNetRoles { get; set; }
    public DbSet<AspNetUserClaim> AspNetUserClaims { get; set; }
    public DbSet<AspNetUserLogin> AspNetUserLogins { get; set; }
    public DbSet<AspNetUser> AspNetUsers { get; set; }
    public DbSet<Author> Authors { get; set; }
    public DbSet<BlogPost> BlogPosts { get; set; }
    public DbSet<CommentEntityTracker> CommentEntityTrackers { get; set; }
    public DbSet<Comment> Comments { get; set; }
    public DbSet<ContactCategory> ContactCategories { get; set; }
    public DbSet<ContactMessage> ContactMessages { get; set; }

2）存储库类，其中将创建整个项目的单个上下文

public class EfRepository<T>:IRepository<T> where T:class
{
   private readonly DbContext _context;
   private readonly DbSet<T> _set;
   public EfRepository()
   {

       _context = new TwiksDbContext();
       _context.Configuration.LazyLoadingEnabled = false;
       _set = _context.Set<T>();
   }

   public void AddEntity(T entity)
   {
       try
       {
           _set.Add(entity);
           _context.SaveChanges();
       }
       catch (Exception ex)
       {
           throw new Exception(ex.Message);
       }
   }

商业逻辑层 1.自定义成员资格类，其中所有Identity方法都在此项目中实现。

public class Membership
{
    private readonly IdentityDbContext _context;
    private UserManager<IdentityUser> userManager;
    private RoleManager<IdentityRole> roleManager;
    //private UserManagerFactory
    public Membership()
    {
        _context = new TwiksDbContext();
       // _context.Configuration.LazyLoadingEnabled = false;

        var userStore = new UserStore<IdentityUser>(_context);
        userManager = new UserManager<IdentityUser>(userStore);
        var roleStore = new RoleStore<IdentityRole>(_context);
        roleManager = new RoleManager<IdentityRole>(roleStore);

    }

    public DbInteractionNotification CreateRole(IdentityRole role)
    {
        try
        {
            if (roleManager.FindByNameAsync(role.Name) != null)
                return DbInteractionNotification.EntryAlreadyExist;
            else
                return (roleManager.CreateAsync(role).IsCompleted) ? DbInteractionNotification.Success : DbInteractionNotification.FatalError;
        }
        catch (Exception)
        {
            return DbInteractionNotification.FatalError;
        }
    }
