HttpClient是否可以同时使用？(Is HttpClient safe to use concurrently?)

 在所有的例子中，我可以找到HttpClient的用法，它用于一次关闭。 但是如果我有一个持久的客户端情况，可以同时发出几个请求？ 基本上，是否可以在同一个HttpClient实例上同时在2个线程上调用client.PostAsync。 
 
 我不是真的在这里寻找实验结果。 作为一个工作实例可能只是一个侥幸（和一个持久的），一个失败的例子可能是一个错误的配置问题。 理想情况下，我正在寻找HttpClient中并发处理问题的一些权威性答案。 

In all the examples I can find of usages of HttpClient, it is used for one off calls. But what if I have a persistent client situation, where several requests can be made concurrently? Basically, is it safe to call client.PostAsync on 2 threads at once against the same instance of HttpClient.
 
I am not really looking for experimental results here. As a working example could simply be a fluke (and a persistent one at that), and a failing example can be a misconfiguration issue. Ideally I'm looking for some authoritative answer to the question of concurrency handling in HttpClient.
