删除连接字符串中的单引号

首先添加以下nuget包：

Scaffold-DbContext "'server=MyPc\SQLEXPRESS;Database=Test;Encrypt=True;TrustServerCertificate=False;'" 'Microsoft.EntityFrameworkCore.SqlServer' -Verbose
Build started...
Build succeeded.
Setting app base path C:\DotNetCoreApps\URShopi\src\URShopi\.\bin\Debug\netcoreapp1.0

然后打开project.json文件并进行以下更改

在依赖项下添加：

Install-Package Microsoft.EntityFrameworkCore.SqlServer

Install-Package Microsoft.EntityFrameworkCore.Tools –Pre

Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design

"Microsoft.EntityFrameworkCore.SqlServer": "1.0.0",

“Microsoft.EntityFrameworkCore.SqlServer.Design”：“1.0.0”， “Microsoft.EntityFrameworkCore.Tools”：“1.0.0-preview2-final”

并在“工具”下添加：

Install-Package Microsoft.EntityFrameworkCore.SqlServer

Install-Package Microsoft.EntityFrameworkCore.Tools –Pre

Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design

"Microsoft.EntityFrameworkCore.SqlServer": "1.0.0",

进行更改后，保存文件

最后再次运行命令-在Package Manager控制台中：

Install-Package Microsoft.EntityFrameworkCore.SqlServer

Install-Package Microsoft.EntityFrameworkCore.Tools –Pre

Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design

"Microsoft.EntityFrameworkCore.SqlServer": "1.0.0",

Scaffold DbContext“Server=；Database=dbname；Trusted_Connection=True；”Microsoft.EntityFrameworkCore.SqlServer-OutputDir模型
