Update ASP.NET Core files without stop IIS Application & Pool in .NET5 feature

[shps951023]

Is your feature request related to a problem? Please describe.

Every time need to stop the IIS Application or Pool to update

or system will show The action can't be completed becacuse the file is open in w3wp.exe

---

Right now my way, I drop a file called app_offline.htm (case sensitive) to my application folder. Let IIS auto stop my application then I update it

From this article iis - How can I update ASP.NET Core app over an existing/running site without stopping the web server? - Stack Overflow

Describe the solution you'd like

I expect like asp.net or mvc, you don't need to stop IIS to update.
