JitBuddy provides a small helper method to disassemble to a x86/x64 ASM listing the native code generated by the JIT of a managed method.

using System;
using System.Reflection;
using JitBuddy;

namespace JitBuddyExample
    public class Program
        public static int Add(int a, int b)
            return a + b;
        static void Main()
            var method = typeof(Program).GetMethod("Add", BindingFlags.Public | BindingFlags.Static);

will produce the following output:

00007FFD515B3FB0 lea       eax,[rcx+rdx]
00007FFD515B3FB3 ret


Starting with .NET Core 3.0 Tiered compilation is enabled and you won't get the best ASM when running this code In order to check the assembly, you should disable tiered compilation (that will fallback to best tiered model) by setting the environment variable set COMPlus_TieredCompilation=0

var method = ...; // Get a MethodInfo via typeof(XXX).GetMethod(...)
var asm = method.ToAsm();


  • On Linux, JitBuddy only works (for now) on CoreCLR 3.0, CoreCLR 2.0-2.2 seem to not be properly supported by ClrMd: #303
