当我尝试访问 .edmx 中的视图时出现此错误:

All artifacts loaded into an ItemCollection must have the same version. Multiple versions were encountered.

这是产生错误的代码:

private IQueryable<daDialogNotes.viewDialogNotesAll> GetAuthorizedList()
    {            
        List<int> authorizedClients = al.GetClientIds();            

        daDialogNotes.NTS2001Entities context = new daDialogNotes.NTS2001Entities();

        IQueryable<daDialogNotes.viewDialogNotesAll> m;
        m = context.viewDialogNotesAlls.Where(x => (authorizedClients.Contains(x.Client_Id))).AsQueryable(); 
        // error in line above          

        return m;
    }

这是我的观点的图像:

在此处输入图像描述

提供者的 App.config:

    <?xml version="1.0" encoding="utf-8"?>

我在所有东西上运行 .net 4.5。edmx 在另一个项目文件中,我在我的应用程序中引用了 dll。谷歌搜索我发现人们在从 .net 3.5 升级到 4.0 时遇到此错误,但这一直在 4.5 上运行。

有任何想法吗?
