我正在开发实现自定义视觉设计器的 VS2012 包（使用 SDK）。该解决方案包含几个项目。当我在 VS 实验实例中运行我的包，然后尝试打开我的自定义可视化设计器时，我收到以下异常：
System.IO.FileNotFoundException was unhandled by user code

看起来像是程序集绑定问题，所以我决定咨询Fusion Log Viewer以获取有关程序集加载器错误的更多信息。
奇怪的是，Fusion 日志说当我尝试打开我的视觉设计器时，有四次尝试加载VisualDesigner.Configuration-两次成功，但也失败了两次：

我不知道为什么会这样。为什么VisualDesigner.Configuration一开始加载成功，但此后加载此程序集会导致失败？
我也想知道为什么在日志中说明Calling assembly : (Unknown).在装配绑定失败的情况下？
