为 .net 4.5.2 安装包 Microsoft.EntityFrameworkCore.SqlServer

Install package Microsoft.EntityFrameworkCore.SqlServer for .net 4.5.2

我正在尝试安装软件包 Microsoft.EntityFrameworkCore.SqlServer 但是 在 PMC 中,我收到以下错误消息:

Install-Package : Could not install package 'Microsoft.EntityFrameworkCore.SqlServer 2.2.6'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5.2', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author. At line:1 char:1 + Install-Package Microsoft.EntityFrameworkCore.SqlServer + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Install-Package], Exception + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand

如何为 .NET Framework 4.5.2 安装它?

You can't

Entity Framework Core 2.x 仅在 .NET Standard 2.0 上运行,meaning 您至少需要以 .NET Framework 4.6.1 为目标。
