将DbConnectionFactory从.net迁移到.NET核心

Question

我正在尝试将一个小的.net框架项目迁移到.net核心项目.但我花了几个小时搜索如何将以下代码用于.net core 2.0.但我不走运,因为似乎System.Data.Common功能因某种原因被削减了.所以,我在这里有两个问题:

1. 如何从连接字符串中获取提供程序名称？我们是否有针对.net core 2.0的ConnectionStringSettings

2. 我们如何只在提供者名称字符串上获得工厂基础？任何其他想法如何执行松耦合数据库连接工厂

   public class ConnectionFactory
   {
       protected readonly DbProviderFactory Factory;
   
       protected readonly string ConnectionString;
   
       public ConnectionFactory(string connectionStringName)
       {
           var settings = ConfigurationManager.ConnectionStrings[connectionStringName];
           this.Factory = DbProviderFactories.GetFactory(settings.ProviderName);
           this.ConnectionString = settings.ConnectionString;
       }
   
       public DbConnection Connection
       {
           get
           {
               var con = Factory.CreateConnection();
               con.ConnectionString = this.ConnectionString;
               return con;
           }
       }
   }
   

Answer 1

DbProviderFactories将在.net core 2.1(2018年第二季度)中提供.
