问题描述

限时删除!!

我偶然发现了一个问题(https://github.com/HTBox/allReady/issues/1313) 在 GitHub 上,他们讨论了从代码中删除 ConfigureAwait(false) 的问题,声称在 ASP.NET Core

I stumbled on an issue (https://github.com/HTBox/allReady/issues/1313) at GitHub where they discussed about taking the ConfigureAwait(false) out of the code, claiming that, in ASP.NET Core

ConfigureAwait(false)的调用是多余的,什么都不做

我能在这里找到的最好的答案是一个旁注"(来自 Stephen Cleary,https://stackoverflow.com/a/40220190/2805831) 告诉

Best I could find here is a "side note" in an answer (from Stephen Cleary, https://stackoverflow.com/a/40220190/2805831) telling that

ASP.NET Core 不再有上下文"

那么,ASP.NET Core 中是否真的不需要 ConfigureAwait(false)(即使使用完整的 .Net Framework)?它在某些情况下是否有真正的性能提升或结果/语义上的差异?

So, is ConfigureAwait(false) really unnecessary in ASP.NET Core (even if using full .Net Framework)? Does it have any real gain in performance in some cases or difference in the result/semantic?

如果我将它作为控制台应用程序或在 IIS 中托管,在这方面是否有所不同?

Is it different in this aspect if I am hosting it as a console application or in IIS?

推荐答案

ConfigureAwait 仅对在 SynchronizationContext 的上下文中运行的代码有影响,而 ASP.NET Core没有(ASP.NETLegacy"有).

ConfigureAwait only has effects on code running in the context of a SynchronizationContext which ASP.NET Core doesn't have (ASP.NET "Legacy" does).

通用代码仍应使用它,因为它可能与 SynchronizationContext 一起运行.

General purpose code should still use it because it might be running with a SynchronizationContext.

ASP.NET Core SynchronizationContext
