오류 db.Database.Migrate()를 실행하는 동안 : 잘못된 구문 키워드를 근처에 'NOT'

Question

여기 내 Dataseeder 클래스의 :

using Microsoft.AspNetCore.Builder; 
using Microsoft.AspNetCore.Identity; 
using Microsoft.AspNetCore.Identity.EntityFrameworkCore; 
using Microsoft.EntityFrameworkCore; 
using Microsoft.Extensions.DependencyInjection;

     public static async void SeedData(this IApplicationBuilder app) 
     { 
      var db = app.ApplicationServices.GetService<ApplicationDbContext>(); 

      //Caution: Clear all the tables in the database first. 
      db.Database.Migrate(); 


      db.SaveChanges(); 
     } 
    } 
} 

기본적으로 오류가 db.Database.Migrate (에서 히트)과 던졌습니다 나에 대해 전혀 몰랐던이 덩어리. 나는 오류의 출처를 찾기 위해 최선을 다했지만 아무 소용이 없었습니다. 마이그레이션 방법의 정의를 확인하려고 시도합니다. 내가 엔티티 관계 구문 오류가

:

기본적으로 마이그레이션하기 전에 자신의 ApplicationDbContext를 확인하십시오.
