如何从netcore成功连接到MySQL。Ubuntu 16.04上的ASP C#

我按照此链接中的说明进行操作

如下图所示。（Program.cs文件）

另外还有ConsoleApp.csproj文件

    <Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp1.1</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Google.Protobuf" Version="3.3.0" />
    <PackageReference Include="MySql.Data" Version="8.0.8-dmr" />
    <PackageReference Include="MySql.Data.EntityFrameworkCore" Version="8.0.8-dmr" />
    <PackageReference Include="MySql.Data.EntityFrameworkCore.Design" Version="8.0.8-dmr" />
  </ItemGroup>
</Project>

首先使用一个简单的控制台应用程序而不是web来简化错误

但毕竟，我一直在犯以下错误

是否有我遗漏的东西或我没有安装的东西或什么！ 求你了，我真的需要你的帮助来找出问题所在。

谢谢

您在此处标记了asp.net-core-mvc，但您使用的是.net core控制台应用程序。哦，感谢您注意到，我在此处使用.netcore控制台应用程序来了解如何连接，然后再在.netcore web应用程序中使用它#立即编辑它。：）@Janesabouchleich请问您是只使用windows操作系统开发C#web应用程序，还是也使用基于Linux的操作系统，如Ubuntu？我在windows上。也有麻烦让它运行。mscorlib是必需的-这表明它不是在.NET核心/标准上运行，而是在完整的.NET框架上运行。您确定MySql.XDevAPI与.NET Core兼容吗？
