Question

我使用： Visual Studio 2017;
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />;
EntityFramework-6.1.4;
JetEntityFrameworkProvider-6.2.0;
WinForm;

MS Access-2016;
数据库-db.accdb;
表格-项目，任务。

EntityFramework，通过Nuget安装的JetEntityFrameworkProvider。

文件App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>

</configuration>

我更改了文件machine.config：
c：\ Windows \ Microsoft.NET \ Framework64 \ v4.0.30319 \ Config \ machine.config

  <DbProviderFactories>
      <add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/>
      <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/>
      <add name="JetEntityFrameworkProvider" invariant="JetEntityFrameworkProvider" description="JetEntityFrameworkProvider" type="JetEntityFrameworkProvider.JetProviderFactory, JetEntityFrameworkProvider, Version=6.0.0.0, Culture=neutral, PublicKeyToken=756cf6beb8fe7b41" />
    </DbProviderFactories>

问题。
如何通过实体框架和JetEntityFrameworkProvider连接到Access（* .accdb）？

更新_1
通过Nuget安装了“ DDEX”

更新_2
我从https://github.com/bubibubi/JetEntityFrameworkProvider下载了该项目

对于项目“ JetDdexProvider”进行“分配启动项目”

按下 F6
收到错误
