【语言-c#】托管调试助手“DisconnectedContext”在“xxx.exe”中检测到问题。 RPC_E_CANTCALLOUT_ININPUTSYNCCALL
问题描述
托管调试助手“DisconnectedContext”在“[ProjectDirectory]\[ProjectName].exe”中检测到问题。
其他信息: 针对此 RuntimeCallableWrapper 向 COM 上下文 0x8306e8 的转换失败，错误如下: 因为应用程序正在发送一个输入同步呼叫，所以无法执行传出的呼叫。 (异常来自 HRESULT:0x8001010D (RPC_E_CANTCALLOUT_ININPUTSYNCCALL))。原因通常是创建此 RuntimeCallableWrapper 的 COM 上下文 0x8306e8 已断开连接，或者该上下文正忙于执行其他操作，无法处理该上下文转换。将不会有代理服务于该 COM 组件上的请求，调用将直接转向该 COM 组件。这可能会导致损坏或数据丢失。要避免此问题，请确保在应用程序全部完成 RuntimeCallableWrapper (表示其内部的 COM 组件)之前，所有 COM 上下文/单元/线程都保持活动状态并可用于上下文转换。
