这是一个托管应用程序，根据 WinDbg 有 61 个进程/线程从该应用程序运行。在 WinDbg 中，当输入 !threads 时，它说没有找到导出线程。它没有说明是什么错误导致了这种情况（在 Visual Studio 2010 中，它说的是 NullReferenceException）。
我要疯了，我以为这与 USB 串行控制器有关，但我把它放到另一个应用程序中，它仍然崩溃（虽然不是像以前那样 100%，而是像 80%）。
这个异常/错误完全让我无法理解，我不知道如何解决它。

正在捕获通信异常（当 WCF 主机未启动时会发生这种情况，并且可能会在断开硬件连接时发生）。我怀疑这是我崩溃的原因，因为在 Visual Studio 中它总是崩溃并出现 NullReferenceException，但没有可用的 CallStack / Disassembly。
例如，当我查看线程 OSID 22C（带有 NullReferenceException 的线程）时，CallStack 是
