IBM DB2 Entityframework问题

Question

如果您知道如何解决此问题，请提供帮助。

VS 2015 Nuget包管理器已安装 - EntityFramework 6.1.3 + IBM DB2 EntityFramework 6.0.6 从数据库创建的EDMX文件。

错误

public partial class dbb1Entities : DbContext
{
    public dbb1Entities()
        : base("name=dbb1Entities"){}
}

错误：

实体框架提供程序类型＆＃39; IBM.Data.DB2.EntityFramework.DB2ProviderServices，IBM.Data.DB2.EntityFramework，Version = 10.5.5.6，Culture = neutral，PublicKeyToken = 7c307b91aa13d208＆＃39;  在具有不变名称＆＃39; IBM.Data.DB2＆＃39;的ADO.NET提供程序的应用程序配置文件中注册无法加载。  确保使用了程序集限定名称，并且程序集可供正在运行的应用程序使用。  有关详细信息，请参阅http://go.microsoft.com/fwlink/?LinkId=260882。

Answer 1

我在使用类似的设置VS2015，EntityFramework 6.2，EntityFramework.IBM.DB2 6.1时遇到了完全相同的问题，但是我设法解决了该问题。

我注意到对.net 4.6.1的引用，将目标框架从4.5.1更改为4.6.1后，问题已解决！

发布在对我有用的IBM应用程序版本/设置下面。
