Framework/Framework64 Directory VS GAC

Question

In my .NET Framework 4.7.2 ConsoleApp with AnyCPU, i am tracing different assemblies loaded in current appdomain with AppDomain.CurrentDomain.GetAssemblies()

  public static void Main(string[] args)
    {  
        Console.WriteLine(typeof(System.Data.CommandBehavior).Assembly.Location);
        Console.WriteLine(typeof(System.Collections.ArrayList).Assembly.Location);
        Console.WriteLine(typeof(HashSet<>).Assembly.Location);
        foreach (var assembly in AppDomain.CurrentDomain.GetAssemblies())
        {
            Console.WriteLine(assembly.Location);
        }
        Console.ReadKey();
    }

and here is the result:

• mscorlib.dll loaded from Framework directory (this path C:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll)
• System.Core.dll loaded from GAC_MSIL Directory (this path C:\windows\Microsoft.Net\assembly\GAC_MSIL\System.Core\v4.0_4.0.0.0__b77a5c561934e089\System.Core.dll)
• System.Data.dll loaded from GAC_32 Directory (this path C:\windows\Microsoft.Net\assembly\GAC_32\System.Data\v4.0_4.0.0.0__b77a5c561934e089\System.Data.dll)

known that the CLR loads assemblies using :

1-GAC

2-Current directory

My questions are :

• what is the role of Framework/Framwork64 Folder in CLR loading assemblies process (i know it's where .net framework runtimes installed)
• Does this CLR loads only runtime assemblies from this folder ? if yes is there any order ?
• My application is targeting AnyCPU why it loads assemblies from GAC_32 instead of GAC_MSIL?
