Question

我正在尝试连接Company和ApplicationUser : IdentityUser之间的一对多关系。在我的ApplicationUser课程中，我有：

 public class ApplicationUser : IdentityUser
 {
    [ForeignKey("CompanyId")]
    public int CompanyId { get; set; }
 }

public class Company
{
    [Key]
    public int CompanyId { get; set; }

    public string Name { get; set; }

    ...
 }

但我收到了System.ArgumentException:

Microsoft.EntityFrameworkCore.Infrastructure.IDbContextFactory 1[TContext]' violates the constraint of type 'TContext'

Answer 1

您可以像这样设置关系。

public class ApplicationUser : IdentityUser
 {

    public Company Company { get; set; }
 }
