It's possible from .Net managed code to cause an arbitrary BSOD?

Question

I wonder whether from .Net managed code, or maybe p/invoking the needed NT dll, if I could generate a BSOD (Blue Screen Of Death) with specific bugcheck-code reason.

I know this is possible from a kernel-mode driver by calling KeBugCheck or KeBugCheckEx methods, but I think there is no way to call those methods from user-mode applications.

Someone could clarify me things, and bring an alternative way (if exists) for managed code?.

I had some code that did exactly that here we go: you might just need ntdll.dll but I used it without installing anything... though the bug check codes don't seem to be the normal types

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using System.IO;

namespace bsod
{
    class Program
    {


        private static uint STATUS_ASSERTION_FAILURE = 0xC0000420;
      //  private static uint KMODE_EXEPTION_NOT_HANDLED=0x0000008E;
        static void Main(string[] args) {

            while (Console.ReadKey(true).Key == ConsoleKey.W) 
            {

                    crash();

            }

        }
        static void crash()
        {

            bool previousValue=false;
           // Console.WriteLine("Adjusting privileges");
            RtlAdjustPrivilege(19, true, false, out previousValue);
           // Console.WriteLine("Triggering BSOD");
            uint oul = 0;
            IntPtr sptr = Marshal.StringToHGlobalAnsi("");
            NtRaiseHardError(STATUS_ASSERTION_FAILURE, 0, 0, IntPtr.Zero, 6, out oul);

        }

        [DllImport("ntdll.dll")]
        private static extern uint RtlAdjustPrivilege(
int Privilege,
bool bEnablePrivilege,
bool IsThreadPrivilege,
out bool PreviousValue
);

        [DllImport("ntdll.dll")]
        private static extern uint NtRaiseHardError(
            uint ErrorStatus,
            uint NumberOfParameters,
            uint UnicodeStringParameterMask,
            IntPtr Parameters,
            uint ValidResponseOption,
            out uint Response
        );

    }
}

let me clarify that this can be very dangerous, as you are one step away from an infinite loop constantly crashing your computer...
