Question

在某些系统（基于VmWare Horizon（最新版本）的虚拟化）上，WaitOne无法在创建互斥锁后直接获取它。需要等待100 ms或使用WaitOne并将超时设置为〜100 ms

代码示例

AttributeError: 'list' object has no attribute 'get'

获取具有错误

System.Threading.Mutex mutex = new System.Threading.Mutex(false, "MutexName");
bool acquire = mutex.WaitOne(0, false)

获取为真

您是否知道这种影响会发生什么，可能与该特定的虚拟化环境有关，还是可能在任何系统上发生？我注意到在常规系统（裸Windows或HyperV）上不会发生此问题。

创建后，WaitOne无法直接获取命名的互斥锁
