IIS是否会回收asp.net核心进程？ [英] Will IIS recycle the asp.net core process?

问题描述

我需要在asp.net核心应用程序中运行长时间运行的后台任务。
我知道Azure Webjobs和其他过时技术，但是我宁愿使解决方案保持简单，并直接在asp.net核心过程中运行这些任务。
我使用Kestrel，应用程序托管在IIS中。

I need to run long running background tasks in my asp.net core application. I know of Azure Webjobs and other out of process techniques but I'd rather keep the solution simple and runs those tasks directly in the asp.net core process. I use Kestrel and the application is hosted in IIS.

我了解IIS有时会回收IIS进程。

I understand that IIS will occasionally recycle the IIS process. Will it also recycle the asp.net core process?

推荐答案

Asp.Net Core< 2.2

Asp.net Core 在单独的进程 dotnet中运行。 exe ，即使它托管在 IIS 中。但这并不意味着它是作为一个独立的过程运行的。 IIS 仍负责 Asp.net核心进程（ dotnet.exe ）通过 AspNetCoreModule 的生命周期。

Asp.net Core runs in a separate process dotnet.exe even when it is hosted in IIS. But it doesn't mean that it runs as an independent process. IIS still responsible for Asp.net core process (dotnet.exe) life cycle through the AspNetCoreModule.

因此，答案是肯定的，IIS还将回收asp.net核心进程

So, answer is yes, IIS will also recycle the asp.net core process

Asp .Net Core> = 2.2

Asp.Net Core 2.2在进程中托管$code> IIS和以前的进程外托管模型不同。看来，这只是一项优化，可以避免将反向代理请求添加到单独的dotnet进程的额外费用。 IIS将使用 Asp.net Core 应用程序

Asp.Net Core 2.2 has in-process hosting support on IIS in addition to out-of-process hosting model that was before. It seems it is just an optimization that allows to avoid the additional cost of reverse-proxying requests over to a separate dotnet process. IIS will recycle application pool with Asp.net Core application
