我将最新的项目复制到显示问题的计算机上，所有。依赖Walker仍然显示与之前相同的黄色图标，但最新的项目可以调试很好。问题显然在我的代码，可能函数签名不匹配的C＃声明和实际DLL实现。

I copied the latest project to the computer that exibited the problem, and it turns out that there is no issue after all. Dependancy Walker still shows the same yellow icons as before, but the latest project can be debugged just fine. The problem was obviously in my code, possibly function signature mismatch between C# declaration and actual DLL implementation.
