IIS Application pools CLR v4.0 vs No managed code

Question

I am currently developing an app which uses .Net core.

I have hosted a lot of micro-services on IIS Manager in new app pool.

I was wondering is there any advantages for app pool version instead of the latest.NET CLR v4.0, to use no managed code?

I heard some things that no managed code option gets better performance. Is that true?

Thank you.

You should use "No managed code" if only an ASP.NET Core app is hosted,

The official guide has made it clear.

What is the consequence of NOT setting "No managed code"? – Pawel Feb 15 '21 at 09:00

@Pawel you are asking for trouble. – Lex Li Feb 15 '21 at 09:01
No, I am genuinely looking for an answer. I want to make my app always running on the IIS as it needs to run background tasks. A couple of solutions are asking to change back to .NET CLR Version v4.0 hence my question. https://docs.hangfire.io/en/latest/deployment-to-production/making-aspnet-app-always-running.html#making-asp-net-core-application-always-running-on-iis – Pawel Feb 15 '21 at 11:34

Again, running background tasks is asking for more trouble. – Lex Li Feb 15 '21 at 15:38
