我有以下用 C++/CX 编写的代码：

TaskPool^ TaskPool::Instance::get()
{
    // Prevent acquiring the critical section for a static initialization
    // after it's been properly initialized.
    if (TaskPool::_instance == nullptr) {

        static CRITICAL_SECTION section;

        CriticalSection lock(&section);

        if (TaskPool::_instance == nullptr) {
            _instance = ref new TaskPool();
            InitializeCriticalSection(GetCriticalSection());
        }
    }
    return _instance;
}

TaskPool^ TaskPool::_instance;
CRITICAL_SECTION TaskPool::_criticalSection;

void Threading::TaskPool::TaskRun(Concurrency::task<void> & task)
{
    Log::LogMessage(this->GetType()->FullName, Level::Debug, "TaskRun [entering]");
    EnterCriticalSection(GetCriticalSection());
    Log::LogMessage(this->GetType()->FullName, Level::Debug, "TaskRun [entered]");

    create_task(task).then([this]() {
        Log::LogMessage(this->GetType()->FullName, Level::Debug, "TaskRun [leaving]");
        LeaveCriticalSection(GetCriticalSection());
        Log::LogMessage(this->GetType()->FullName, Level::Debug, "TaskRun [left]");
    });
}

TaskPool …
