Here is my solution that works both in .net 2 and 4. hInstance is ProcessModule.BaseAddress.

public static class ModuleHelper
    {
        public static ProcessModule GetCurrentModule()
        {
            // need instance handle to module to create a system-wide hook
            Module[] list = System.Reflection.Assembly.GetExecutingAssembly().GetModules();
            System.Diagnostics.Debug.Assert(list != null && list.Length > 0);

            var currentProcess = Process.GetCurrentProcess();
            var modules = currentProcess.Modules;
            ProcessModule mod = null;
            foreach (ProcessModule m in modules)
                            //for .net 2 we will find module here
                if (m.ModuleName == list[0].Name)
                {
                    mod = m;
                    break;
                }

                    //for .net 4 take current module
            if (mod == null)
                mod = Process.GetCurrentProcess().MainModule;

            return mod;
        }
    }
