我有一个应用程序是另一个商业应用程序的插件，我的所有代码都在 .NET 4.0 中。显示特定对话框时，用户收到错误消息“动态程序集中不支持调用成员”。我对此进行了研究，发现所有问题都是在运行时或通过反射加载程序集的问题（正如错误所暗示的那样。但是，我的情况有两个奇怪的部分我无法弄清楚：
- 这似乎只发生在 32 位操作系统上，而不是 64 位操作系统上。
- 该对话框非常简单，它有 1 个枚举、几个属性和一些事件处理程序。我看不到任何地方正在调用任何应该创建它的东西。看起来错误是在调用“ShowDialog()”时引发的，但对话框中甚至没有用于显示窗口时的处理程序。
代码如下（ps 这是 WPF，所以我同时包含了 xaml 和 .vb 代码。
