Missing asp.net features on IIS 10.0

I'm using IIS 10.0 and ASP.NET feature section isn't showing

My environment: Windows Server 2016

My issue is similar to the issue posted here: No asp.net features on IIS 7.5 and No ASP.NET features shown in IIS 7.5

The 'add features' fix mentioned in those posts doesn't apply as it was already correctly configured that (see image)

This section's appearance is also triggered by the application pool's .NET CLR version.

I encountered this when I added two copies of the same .NET 5 (Core) application to IIS. Each had their own app pool which used the "No Managed Code" .NET CLR version. I was surprised to find that one had the ASP.NET section but the other didn't.

Turns out I had initially created one of the app pools with the default setting for .NET CLR version of V4.0. Even though I had corrected this it still showed the ASP.NET section for the corresponding application until I removed the application and added it back in.

I had the same scenario as the OP, but I hadn't restarted IIS manager. When I closed and reopened IIS, the ASP.NET section was present

From the Screenshots in the OPs questions I deduced that mine simply weren't selected in the server roles section of the server administrator. For clarity I added these:

"Add roles and features" 
    -> "Server Roles"     
       -> "Web Server (iis)" 
          -> "Web Server" 
             -> "Application Development" 
                -> "ASP.NET 4.6" (I also needed 3.5 for legacy reasons)

Then restart IIS manager (just close the window and reopen it)

We applied updates to the server, rebooted and then this bug went away. Magically the asp.net section appeared.
