如何在不与其他迁移冲突的情况下很好地实现迁移？

问题描述

我想更新数据库，但是我首先需要首先启用迁移到目标数据库列 当我在控制台上使用此命令时

Enable-Migrations
More than one context type was found in the assembly 'eNtsaRegistrationTraining'.
To enable migrations for 'eNtsaRegistrationTraining.Models.ApplicationDbContext',use Enable-Migrations -ContextTypeName eNtsaRegistrationTraining.Models.ApplicationDbContext.
To enable migrations for 'eNtsaRegistrationTraining.DAL.eNtsaRegCourses',use Enable-Migrations -ContextTypeName eNtsaRegistrationTraining.DAL.eNtsaRegCourses.
To enable migrations for 'eNtsaRegistrationTraining.DAL.eNtsaRegistration',use Enable-Migrations -ContextTypeName eNtsaRegistrationTraining.DAL.eNtsaRegistration.
PM> Enable-Migrations -ContextTypeName eNtsaRegistrationTraining.DAL.eNtsaCourses
The context type 'eNtsaRegistrationTraining.DAL.eNtsaCourses' was not found in the assembly 'eNtsaRegistrationTraining'.

我只需要一个eNtsaCourses，如何使用命令控制台解决此问题？

解决方法

Enable-Migrations -ContextTypeName eNtsaRegistrationTraining.DAL.eNtsaRegCourses -force
