If this code wasn't needed anymore, is

runtime/src/libraries/System.Private.CoreLib/src/System/Reflection/AssemblyNameFormatter.cs

Lines 74 to 75 in 4c92aef

if (contentType == AssemblyContentType.WindowsRuntime)
sb.Append(", ContentType=WindowsRuntime");
still needed?

I believe that can also be removed.

I think that one is reachable:

using System;

Console.WriteLine(AssemblyName.GetAssemblyName(@"C:\Windows\System32\WinMetadata\Windows.UI.winmd"));
Windows.UI, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null, ContentType=WindowsRuntime


object? o = CreateInstance(type!, bindingAttr, binder, args, culture, activationAttributes);
