Here is the code that I extracted out of my application code (which I
cannot post here).

In my excitement to get reply, I might have forgotten something,
apologies in advance for that.

        private void AddProfilingMethodToAssembly()
        {
                var md = new MethodDefinition("ProfilerMEthod", // was
ProfilerMethodInSourceAssembly in source assembly
                                          MethodAttributes.HideBySig |
MethodAttributes.Static | MethodAttributes.CompilerControlled,
 
assemblyDefinition.MainModule.Import(typeof(string)));

                //add it to <Module> class
                typeDefinition.Methods.Add(md);

                //Generate the parameters
                md.Parameters.Add(new ParameterDefinition("v",
ParameterAttributes.None,
assemblyDefinition.MainModule.Import(typeof(string))));

                //create a method body
                md.Body = new MethodBody(md);

            var body = md.Body;

            foreach (var mi in typeof(string).GetMethods())
            {
                var mr =
body.Method.Module.Assembly.MainModule.Import(mi);
                body.Method.Module.Assembly.MainModule.Import(mr);
            }

            var methodBody = ProfilerMethodDefiniton();

            body.InitLocals = true;

            foreach (var local in methodBody .Body.Variables)
            {
                body.Variables.Add(local);
            }

            body.Instructions.Clear();

            var worker = body.GetILProcessor();

            foreach (var instruction in methodBody.Body.Instructions)
            {
                worker.Append(instruction);
            }
        }

        public MethodDefinition ProfilerMethodDefiniton()
        {
            //I am trying to extract method from currently running
assembly
            var asm =
AssemblyDefinition.ReadAssembly(System.Reflection.Assembly.GetExecutingAssembly().Location);

            foreach (var type in asm.MainModule.GetAllTypes())
            {
                foreach (var methodDefinition in type.Methods)
                {
                    if
(methodDefinition.Name.Equals("ProfilerMethodInSourceAssembly"))
                        return methodDefinition;
                }
            }
            return null;
        }

        // this is the method that is present in currently executing
assembly, but gets added to target assembly
        public static void ProfilerMethodInSourceAssembly(string
value)
        {
           // do something with the string here
        }

Thanks
Vijay
