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.
