asp.net-core – 程序集中找不到入口点’Microsoft.EntityFrameworkCore.Design – dotnet.exe崩溃

前端之家收集整理的这篇文章主要介绍了asp.net-core – 程序集中找不到入口点’Microsoft.EntityFrameworkCore.Design – dotnet.exe崩溃前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
请在下面查看Package Manager控制台中提供的数据.我无法进行添加迁移.当我做dotnet.exe崩溃.
PM> Add-Migration 1
Unhandled Exception: System.MissingMethodException: Entry point not found in assembly 'Microsoft.EntityFrameworkCore.Design,Version=1.0.1.0,Culture=neutral,PublicKeyToken=adb9793829ddae60'.
PM> dotnet --info
.NET Command Line Tools (1.0.0-preview2-003131)

Product Information:
 Version:            1.0.0-preview2-003131
 Commit SHA-1 hash:  635cf40e58

Runtime Environment:
 OS Name:     Windows
 OS Version:  10.0.14393
 OS Platform: Windows
 RID:         win10-x64

解决方法

我通过删除Design参考并仅使用工具参考解决了这个问题.

编辑:

随着时间的推移给我另一个错误,从我可以告诉的问题是微软更新了他们的设计包而不是他们的工具包,所以两者都不能一起工作,因为如果你按照他们的教程,它应该得到你得到的最新包遵循它的错误.

我通过强制两个包到1.0.0-preview2-final来解决它.
我更新的project.json:
