How to turn an ARX Application into a Managed C++ Application?By Philippe Leefsma
You can directly create a mixed manage project using ObjectARX wizard. The steps below apply to projects which are being migrating from old releases or converting a unmanaged ObjectARX project to a mixed managed.

The first thing to do is to turn on the /CLR compiler setting to compile as managed.
In the project properties window, under the Property Pages for the project, make the following modifications:
C++ :  General:
     
    Compile As Managed   
     From: Not using managed extensions   
     To: Assembly Support (/clr)
    Debug Information Format: (Debug only)     
    From: Program Database for Edit & Continue (/ZI)   
    To: Program Database (/Zi)

Code Generation (Debug only):
   
    Basic runtime checks     
     From: Both (/RTC1, equip, to /RTC Su...)   
     To: default

Precompiled Header:   

    Create/Use Precompiled Header   
     From: Automatically Generate (/YX)   
     To: Create Precompiled Header (/Yc)

Code Generation:
   
    Enable Minimal Rebuild   
     From: Yes (/Gm)   
     To: No

Link with the /NOENTRY flag

In stdafx.h add:
#using <mscorlib.dll>   
#using <System.dll>
#using <System.Drawing.dll>
#using <system.windows.forms.dll>

In the CPP file where you're going to use managed code, add the following after the compiler references through to stdafx.h
using namespace System;
using namespace System::Reflection;
using namespace System::Collections;
using namespace System::ComponentModel;
using namespace System::Drawing;
using namespace System::Windows::Forms;
using namespace System::Security::Policy;
using namespace System::Runtime::InteropServices;

See attached sample for more details.
