在VS 2017中添加ADO.NET实体数据模型并且什么也没有发生 [英] Adding ADO.NET Entity Data Model in VS 2017 and nothing happens

问题描述

在Visual Studio的实体数据模型向导中选择MySQL数据源并单击下一步后，该向导将关闭。怎么了？

After selecting the MySQL data source in the Entity Data Model wizard in Visual Studio and clicking on "Next", the wizard just closes. What's going wrong?

推荐答案

• 从 6.9.10 = https://downloads.mysql.com/archives/c-net/ rel = nofollow noreferrer> https://downloads.mysql.com/archives/c-net/ ，因为较新8.0似乎有问题。


• 在Package Manager控制台中安装：


• Install old version of MySql Connector like 6.9.10 from https://downloads.mysql.com/archives/c-net/ , Because the newer 8.0 appearto have problems.
• In Package Manager Console Install:

Install-Package MySQL.Data -Version 6.9.9
Install-Package MySql.Data.Entity -Version 6.9.10







• 不要忘记在web.config中添加此行



<system.data>
    <DbProviderFactories>
      <remove invariant="MySql.Data.MySqlClient" />
      <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.9.10.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
    </DbProviderFactories>
  </system.data>
