Question

我正在尝试将MySQL Data Nuget包添加到我的ASP Web Core项目中，但是我收到此错误：

一个或多个软件包与.NETCoreApp，Version = v1.1（win-x86）不兼容。

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

这是我的.csproj的样子：

    </ItemGroup>

如何解决此错误？

Answer 1

从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包中包含.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：

查找另一个支持.NET Standard，PCL或.NET Core的MySql NuGet包或库。例如MySqlConnector。
将项目更改为目标.NET Core 2.0。
- 需要测试MySql.Data NuGet包以确定它是否与.NET Core 2.0兼容。虽然您可以使用从.NET Core 2.0项目中定位.NET的NuGet包，但不能保证程序集能够正常工作，因为它可能正在使用.NET Core 2.0不支持的某些API。

无法将MySQL Data Nuget包添加到ASP Core Project
