저는 nopCommerce 기반 프로젝트에서 작업 중입니다. 사용자 지정 엔터티를 업데이트하기 위해 EF 마이그레이션을 사용하려고합니다. 그래서 다음 명령을 실행어셈블리에서 컨텍스트 유형을 찾을 수 없습니다. EF6
Enable-Migrations -StartUpProjectName nop.web -ContextProjectName Nop.Plugin.Payments.Deposit -verbose
및 오류 얻을 :

컨텍스트 클래스는 다음과 같이 정의된다 : 제작 한

}
빈 프로젝트가 마이그레이션을 활성화 . 내가 추가 마이그레이션을 실행할 때 나는 오류 다음 얻을
namespace Nop.Plugin.Payments.Deposit.Migrations

internal sealed class Configuration : DbMigrationsConfiguration<DepositTransactionObjectContext>
{
public Configuration()
{
AutomaticMigrationsEnabled = true;

내가 같은 질문을 많이 읽고은 다음과 같습니다 그래서 그 때 나는 Configuration.cs를 복사 조정했습니다 그 이유는 Enable-Migrations cmdlet (컨텍스트가 정의되지 않은 cmdlet)에 잘못된 프로젝트가 지정된 이유였습니다. 그러나 당신이 볼 수있는 것처럼 그것은 나의 경우가 아닙니다.
그 밖의 이유는 무엇입니까?
나는 그것을 시도했다. 결과는 동일합니다. – Ralfeus
