C# 为什么Mono的Evaluator.Evaluate（）会导致FileLoadException-AssemblyResolveEvent处理程序无法返回仅为反射而加载的程序集？

c# mono

C# 为什么Mono的Evaluator.Evaluate（）会导致FileLoadException-AssemblyResolveEvent处理程序无法返回仅为反射而加载的程序集？,c#,mono,assembly-resolution,C#,Mono,Assembly Resolution,我有以下代码： public static void Run() { var reportPrinter = new ConsoleReportPrinter(); var compilerSettings = new CompilerSettings(); var compilerContext = new CompilerContext(compilerSettings, reportPrinter); var

我有以下代码：

    public static void Run()
    {
        var reportPrinter = new ConsoleReportPrinter();
        var compilerSettings = new CompilerSettings();
        var compilerContext = new CompilerContext(compilerSettings, reportPrinter);

        var evaluator = new Evaluator(compilerContext);

        var loadedBefore = AppDomain.CurrentDomain.GetAssemblies();
        Assembly[] loadedAfter;
        try
        {
            var result = evaluator.Evaluate("1+2");
        }
        catch (Exception)
        {
            loadedAfter = AppDomain.CurrentDomain.GetAssemblies();
            throw;
        }
    }

此代码在toy独立项目中运行良好，但一旦我将其放入主项目中，evaluator.Evaluate将调用FileLoadException-AssemblyResolveEvent处理程序无法返回仅为反射而加载的程序集

不幸的是，我对造成这种情况的原因知之甚少，而且由于不太熟悉.NET的内部结构，我对如何诊断这种情况的想法甚至更少

我的主要项目确实有很多依赖项，它们使用某种形式的元编程NHibernate、ActiPro语法编辑器、DevExpress、Antlr。该项目本身也使用Microsoft的CodeDOM在同一AppDomain中编译和执行用户脚本——是的，我知道存在一些问题。我在过去也遇到过同样的例外情况——它是通过清理我的库文件并再次从其他开发人员那里复制来修复的。我们一直没有弄清那件事的真相。我不确定这是否表明依赖项之间存在某种版本不匹配

无论如何，引发异常时的loadedBefore变量与loadedAfter相同。它包含以下内容：

        ...

然后，assemblyLoadedEventLog包含：

对我来说，最令人费解的事情是底部条目——究竟为什么系统程序集要在这里仅在反射上下文中加载？这是跨应用程序域的混淆吗
