C++ create_task详解

IAsyncOperation^ asyncOperation = create_async( []() {
    return create_task(FirstAsync(...))
    .then( [](X val){
        return SecondAsync(val, ...);
    }).then( [](Y val)
        return ThirdAsync(val, ...);
    });

 

这段代码会执行FirstAsync->SecondAsync->ThirdAsync，最后返回的是 ThirdAsync的结果。
