ASP.NET 核心 Web API - 如何在实体框架结果中获取所有员工用户详细信息和角色

Question

I am implementing ASP.NET Identity Db Context, in ASP.NET Core-6 Web API Entity Framework. I have these models:

public class Employee
{
    public Guid Id { get; set; }
    public string UserId { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string MobileNumber { get; set; }
    public Guid DepartmentId { get; set; }

    public virtual ApplicationUser User { get; set; }
}

public class ApplicationUser : IdentityUser
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string MobileNumber { get; set; }

    [DefaultValue(false)]
    public bool? IsAdmin { get; set; }
}

public class ApplicationRole : IdentityRole
{
    public bool? IsActive { get; set; }
}

Entity Configuration:

public class ApplicationRoleConfigurations : IEntityTypeConfiguration<ApplicationRole>
{

    public void Configure(EntityTypeBuilder<ApplicationRole> builder)
    {
        builder.HasIndex(r => r.Name).IsUnique();
        builder.Property(r => r.IsActive).HasDefaultValue(true);
    }
}

public class ApplicationUserConfigurations : IEntityTypeConfiguration<ApplicationUser>
{
    public void Configure(EntityTypeBuilder<ApplicationUser> builder)
    {
        builder.HasIndex(u => u.Email).IsUnique();
        builder.HasIndex(u => u.UserName).IsUnique();
        builder.Ignore(u => u.AccessFailedCount);
        builder.Ignore(u => u.LockoutEnabled);
        builder.Ignore(u => u.TwoFactorEnabled);
        builder.Ignore(u => u.ConcurrencyStamp);
        builder.Ignore(u => u.LockoutEnd);
        builder.Ignore(u => u.EmailConfirmed);
        builder.Ignore(u => u.TwoFactorEnabled);
        builder.Ignore(u => u.AccessFailedCount);
        builder.Ignore(u => u.PhoneNumberConfirmed);
        builder.Property(u => u.IsActive).HasDefaultValue(true);
        builder.Property(u => u.IsAdmin).HasDefaultValue(false);
    }
}

Then, I have this query to get all the employees with their user details and roles:

public IQueryable<Employee> GetAllEmployees(PagingFilter filter)
{
    var employees = _dbContext.Employees
                    .Include(x => x.User);
    return employee;
}

But it is not giving me the desired result.

How do I get all the employees with their user details and roles?

Thanks
