我的代码就像这样
namespace DiagnosisApp.Models
{
public class ApplicationUser : IdentityUser
{
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DiagnosisContext")
{
}
}
}
namespace DiagnosisApp.DAL
{
public class DiagnosisInitializer : DropCreateDatabaseIfModelChanges<DiagnosisContext>
{
protected override void Seed(DiagnosisContext context)
{
var userManager = new UserManager<ApplicationUser>(new
UserStore<ApplicationUser>(context));
var roleManager = new RoleManager<IdentityRole>(new
RoleStore<IdentityRole>(context));
string name = "Admin";
string password = "123456";
//Create Role Admin if it does not exist
if (!roleManager.RoleExists(name))
{
IdentityResult roleresult = roleManager.Create(new IdentityRole(name));
}
//Create User=Admin with password=123456
var user = new ApplicationUser();
user.UserName = name;
IdentityResult adminresult = userManager.Create(user, password);
//Add User Admin to Role Admin
if (adminresult.Succeeded)
{
IdentityResult result = userManager.AddToRole(user.Id, name);
}
base.Seed(context);
}
}
}
namespace DiagnosisApp.DAL
{
public class DiagnosisContext : DbContext
{
public DiagnosisContext()
: base("DiagnosisContext")
{
Database.SetInitializer(new DiagnosisInitializer());
}
}
}
一切看起来都没问题,但这会引发错误
实体类型IdentityRole不是当前上下文的模型的一部分。
在第
行 if (!roleManager.RoleExists(name))
有谁可以指出我在这里做错了什么?

检查DiagnosisContext类是否具有如下有效签名:
public class DiagnosisContext : IdentityDbContext<MyUser>
或
public class DiagnosisContext : IdentityDbContext

你的种子方法
protected override void Seed(DiagnosisContext context)
正在接受仅从香草DbContext继承的DiagnosisContext
。你应该传递ApplicationDbContext
protected override void Seed(ApplicationDbContext context)
DbContext上没有IdentityRole。
