c# - 我如何解决 Cannot create a DbSet for 'CUserMasterLocal' because this type is not included in the model for the context

Question

我试图将我的应用程序和身份处理保留在它们自己单独的上下文中，但我遇到了错误消息

Cannot create a DbSet for 'CUserMasterLocal' because this type is not included in the model for the context.

从我的在线研究看来，我需要让 ApplicationDBContext 从 IdentityDbContext 继承，而不是 DBContext，但如前所述，我想必须在自己的上下文中进行身份管理。至少有一篇 Stack Overflow 帖子告诉我这是不允许的，有任何社区设法在自己的上下文中保持身份吗？

这是我的身份上下文:

public class AppIdentityDbContext : IdentityDbContext<CUserMasterLocal, CRoleMasterLocal, string>
{
    public AppIdentityDbContext(DbContextOptions<AppIdentityDbContext> options)
    : base(options) { }
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);

        // Customizations must go after base.OnModelCreating(builder)

        var x = builder.Entity<CUserMasterLocal>(config =>
        {
            // Set the default table name of AspNetUsers
            config.ToTable("AspNetUsers");
        });


        builder.Entity<CRoleMasterLocal>(config =>
        {
            config.ToTable("RoleMaster");
        });
    }
    public DbSet<CUserMasterLocal> UserMaster { get; set; }
    public DbSet<CRoleMasterLocal> RoleMaster { get; set; }
}

在 startup.cs 我有

var identityConnectionString = this.Configuration["Data:VT_LocalIdentityData:ConnectionString"];
services.AddDbContext<AppIdentityDbContext>(options =>
    options.UseSqlServer(identityConnectionString));
services.AddIdentity<CUserMasterLocal, CRoleMasterLocal>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();

在我的 Controller 中，我通过“ block ”隔离了身份事件

using (var localIdContext = new AppIdentityDbContext(optionsBuilder.Options))
{
    CUserMasterLocal userMaster = CreateUserMasterEntry(person, 
        userDetails.GetUsername());

    IdentityResult result = this.userManager.CreateAsync(userMaster, 
        GeneratePassword(12)).Result;
}

为避免疑义，CUserMasterLocal 未在设置 ApplicationDBContext 的类中引用，我希望保持这种状态。

当您注册您的身份服务时，您是否打算将 ApplicationDbContext 作为您的 EntityFrameworkStores？

尝试替换

services.AddIdentity<CUserMasterLocal, CRoleMasterLocal>()
            .AddEntityFrameworkStores<ApplicationDbContext>() // <--- this doesn't seem right.
            .AddDefaultTokenProviders();

与

services.AddIdentity<CUserMasterLocal, CRoleMasterLocal>()
            .AddEntityFrameworkStores<AppIdentityDbContext>() // <--- this is changed
            .AddDefaultTokenProviders();
