包"Microsoft.EntityFrameworkCore.SqlServer"与项目中的“所有"框架不兼容 [英] Package 'Microsoft.EntityFrameworkCore.SqlServer' is incompatible with 'all' frameworks in the project

问题描述

我试图通过运行命令添加名为 Microsoft.EntityFrameworkCore.SqlServer 的程序包.

I was trying to add the package named Microsoft.EntityFrameworkCore.SqlServer by running the command.

dotnet add package Microsoft.EntityFrameworkCore.SqlServer

在Visual Studio代码中，但出现此错误:

in Visual Studio Code, but I get this error:

软件包Microsoft.EntityFrameworkCore.SqlServer 2.0.0与netcoreapp1.1(.NETCoreApp，Version = v1.1)不兼容.软件包Microsoft.EntityFrameworkCore.SqlServer 2.0.0支持:netstandard2.0(.NETStandard，Version = v2.0).软件包'Microsoft.EntityFrameworkCore.SqlServer'与项目'C:\ users \ username中的'all'框架不兼容..'

Package Microsoft.EntityFrameworkCore.SqlServer 2.0.0 is not compatible with netcoreapp1.1 (.NETCoreApp,Version=v1.1). Package Microsoft.EntityFrameworkCore.SqlServer 2.0.0 supports: netstandard2.0" (.NETStandard,Version=v2.0). Package 'Microsoft.EntityFrameworkCore.SqlServer' is incompatible with 'all' frameworks in project 'C:\users\username..'

推荐答案

我正在使用1.1版.尝试运行以下命令，包括版本号:

I was using version 1.1. Try to run the below command including the version number:

Visual Studio代码:

'dotnet添加软件包Microsoft.EntityFrameworkCore.SqlServer -v 1.1.1'

'dotnet add package Microsoft.EntityFrameworkCore.SqlServer -v 1.1.1'

Visual Studio:-

安装软件包Microsoft.EntityFrameworkCore.SqlServer -v 1.1.1"

'Install-Package Microsoft.EntityFrameworkCore.SqlServer -v 1.1.1'
