我创建了一个扩展“IdentityUser”类的Model.
public class ApplicationUser : IdentityUser
{
public string FirstName_TXT { get; set; }
public string LastName_TXT { get; set; }
}
在定义dbcontext时,我确保包含IdentityDbContext以及ApplicationUser Reference.
//initial DB Configuration
public class DbContext : IdentityDbContext<ApplicationUser>
{
//Users References Articles
//Articles Automaticalled gets create
public DbSet<ContactRequest> ContactRequests { get; set; }
public DbSet<Class> Classes { get; set; }
public DbContext()
{
}
public DbContext(DbContextOptions options)
: base(options)
{
}
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UsesqlServer(@"Server=.\sqlEXPRESS;Database=DBNAME;Trusted_Connection=True;");
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
}
}
当我尝试使用控制台应用程序中的其他字段创建数据库时,出现以下错误.
class Program
{
static void Main(string[] args)
{
using (var ctx = new DbContext())
{
ctx.Database.EnsureCreatedAsync();
ctx.SaveChanges();
}
}
}
System.InvalidOperationException: ‘A key cannot be configured on ‘ApplicationUser’ because it is a derived type. The key must be configured on the root type ‘IdentityUser’. If you did not intend for ‘IdentityUser’ to be included in the model,ensure that it is not included in a DbSet property on your context,referenced in a configuration call to ModelBuilder,or referenced from a navigation property on a type that is included in the model.’
不确定我错过了什么.任何建议将不胜感激.
