无法将 MySQL 数据 Nuget 包添加到 ASP 核心项目

Question

我正在尝试将 MySQL Data Nuget 包添加到我的 ASP Web Core 项目中，但出现此错误：

One or more packages are incompatible with .NETCoreApp,Version=v1.1 (win-x86).

我正在为 Mac 使用 Visual Studio。这是我得到的完整错误日志：

这是我的 .csproj 的样子：

    </ItemGroup>
    <ItemGroup>

    </ItemGroup>
    <ItemGroup>
        <Compile Remove="Model\ResponseCallBack.cs" />
    </ItemGroup>
</Project>

我该如何解决这个错误？

来自 NuGet 输出：

Package MySql.Data 6.9.9 is not compatible with netcoreapp1.1 (.NETCoreApp,Version=v1.1). Package MySql.Data 6.9.9 supports: - net40 (.NETFramework,Version=v4.0) - net45 (.NETFramework,Version=v4.5)

MySql.Data NuGet 包包含 .NET 4.0 和 4.5 的程序集。您不能在 .NET Core 1.1 项目中使用它们。

选项：

查找另一个 MySql 支持 .NET Standard、PCL 或 .NET Core 的 NuGet 包或库。例如MySqlConnector。
将您的项目更改为面向 .NET Core 2.0。
- MySql.Data NuGet 包需要测试以查看它是否与 .NET Core 2.0 兼容。虽然您可以使用 .NET Core 2.0 项目中以 .NET 为目标的 NuGet 包，但不能保证程序集能够正常工作，因为它可能使用了一些 .NET Core 2.0 不支持的 API。
