可调试不适用于通过反射加载的程序集 [英] Debuggable does not work for assemblies loaded via reflection

问题描述

我有一个相当复杂的场景.假设我们有3个程序集:a.exe，b.dll和c.dll. b.dll引用c.dll.我启动a.exe，它会执行以下操作:

I have a rather complicated scneario. Let's say we have 3 assemblies: a.exe, b.dll and c.dll. b.dll references c.dll. I start a.exe, it does the following:

1.通过反射(Assembly.LoadFrom("b.dll"))加载b.dll

1. Loads b.dll via reflection (Assembly.LoadFrom ("b.dll"))

2.暂停并等待用户附加调试器.

2. Pauses and waits for the user to attach a debugger.

现在，我将VS附加到a.exe上，然后检查加载的模块.我可以看到b.dll并不是经过优化的，但是c.dll是经过优化的，尽管两者都是使用/optimize-选项构建的.我还通过IL Spy验证了c.dll确实已使用Debuggable属性进行了标记.如果我创建 一个d.exe并直接引用c.dll并在VS中调试d.exe，则c.dll尚未优化.因此，我很确定是c.dll的加载方式使其无法调试.

Now I attach VS on a.exe and I examine loaded modules. I can see that b.dll is not optimized but c.dll is, although both are built with /optimize- option. I have also verified with IL Spy that c.dll is indeed tagged with Debuggable attribute. If I create a d.exe and reference c.dll directly and debug d.exe in VS, c.dll is not optimized. So I'm pretty sure it's how c.dll is loaded that makes it not debuggable.

有什么想法为什么会这样?假设不能直接从VS启动a.exe.谢谢.

Any ideas why this is happening? Let's assume launching a.exe from VS directly is not an option. Thanks.
