如何在 ASP.NET 5 中将 Entity Framework 6 与 MySQL 一起使用?

Since Web.config is no longer used with ASP.NET 5, you need to use code-based configuration to configure it instead. To do so, create a new class that inherits from DbConfiguration:

public class MyDbConfiguration : DbConfiguration
{
    public MyDbConfiguration()
    {
        // Register ADO.NET provider
        var dataSet = (DataSet)ConfigurationManager.GetSection("system.data");
        dataSet.Tables[0].Rows.Add(
            "MySQL Data Provider",
            ".Net Framework Data Provider for MySQL",
            "MySql.Data.MySqlClient",
            typeof(MySqlClientFactory).AssemblyQualifiedName
        );

        // Register Entity Framework provider
        SetProviderServices("MySql.Data.MySqlClient", new MySqlProviderServices());
        SetDefaultConnectionFactory(new MySqlConnectionFactory());
    }
}

配置的第一部分是通过向 system.data 部分动态添加新配置条目来在运行时注册 ADO.NET 提供程序的 hack.这很 hacky，但似乎可以正常工作.

{
  "Data": {
    "DefaultConnection": {
      "ConnectionString": "Server=localhost; Database=test; Uid=test; Pwd=password;"
    }
  }
}

[DbConfigurationType(typeof(MyDbConfiguration))]
public class MyContext : DbContext
{
    public MyContext(IConfiguration config)
      : base(config["Data:DefaultConnection:ConnectionString"])
      {
      }
      // ...
}

public void ConfigureServices(IServiceCollection services)
{
    // ...
    services.AddScoped<MyContext>();
}
