Question

我正在使用带有MySQL数据库的Entity Framework。

尝试对数据库进行查询时，出现以下错误：

Model2.ssdl(2,96) : error 0004: Could not load file or assembly 'MySql.Data.Entity, Version=6.8.0.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

我想回到之前的版本，这似乎有用。

尝试在NuGet包管理器控制台中卸载MySql.Data时，出现以下错误：

PM> Uninstall-Package MySql.Data -Version 6.8.0-alpha
Uninstall-Package : Unable to uninstall 'MySql.Data 6.8.0-alpha' because 'MySQL.Data.Entities 6.7.4.1' depends on it.

Answer 1

您可以对-Force命令使用Uninstall-Package参数。

Uninstall-Package MySql.Data -Force

然后你可以安装最新的稳定版本：

Install-Package Mysql.Data

如何从Visual Studio（NuGet）卸载MySql.Data版本6.8.0-alpha？
