当你说 Task.Run 时，你是说你有一些 CPU 工作要做，这可能需要很长时间，所以它应该始终在线程池线程上运行.

When you say Task.Run, you are saying that you have some CPU work to do that may take a long time, so it should always be run on a thread pool thread.

当您说 ConfigureAwait(false) 时，您是说该 async 方法的其余部分不需要原始上下文.ConfigureAwait 更像是一个优化提示；它并不总是意味着延续在线程池线程上运行.

When you say ConfigureAwait(false), you are saying that the rest of that async method does not need the original context. ConfigureAwait is more of an optimization hint; it does not always mean that the continuation is run on a thread pool thread.
