c# - 无法加载文件或程序集 mscorlib.dll!System.AppDomain.OnAssemblyResolveEvent

Question

当我在 VS 2019 IDE 中运行我的 Winforms XAF 实体框架应用程序时

鉴于我在公共语言运行时异常中启用了 System.IO.FileNotFound 异常。

我收到此运行时错误。

System.IO.FileNotFoundException：'无法加载文件或程序集'DevExpress.Persistent.BaseImpl.EF.v20.2，Version=20.2.5.0，Culture=neutral，PublicKeyToken=b88d1754d700e49a'或其依赖项之一。该系统找不到指定的文件。'

调用堆栈是

我之前遇到过这个错误，并在这里向 Dev Express报告，但问题消失了。

源代码是

    private static bool CheckMigrationVersionAndAskToUpgradeIfNeeded()
    {
        try
        {
            using (var db = new MigrationDbContext())
            {
                var compatible = db.Database.CompatibleWithModel(false);
                if (!compatible) compatible = RunMigrationsIfPresent(db);
                return compatible;
            }
        }
        catch (Exception ex)
        {
            var s = string.Format("Problem in MigrateIfNeeded \r\n" + ex);
            MessageBox.Show(s);
            return false;
        }
    }

实体框架是 v6.4.4

目标框架是 .Net Framework 4.7.2

从调用堆栈看来，GetTypeByName 正在解析为错误的类型。我该如何解决？

我不确定这个问题是否相关
