MS VC++ .NET (2002) - Fatal Error LNK1561:entry point must be defined

[Scott Chang]

Hi all,
I have Microsoft Visual C++ .NET (2002) program that is
installed on my Windows XP Professional Operating System
PC. I started my project (named HelloMCPP)in the Managed
C++ Application and added a DLL in the .h file to my
project for printing "Hello from Managed C++!" out in my
console. I did "Build" the program 'HelloMCPP' and I
got 'Fatal Error LNK1561: entry point must be defined
HelloMCPP'. I do not know how to define the entry point
in this project. Please help and advise how to define it
and get this project executed.
Thanks in advanve,
Scott Chang

The following is the souce code of my HelloMCPP:
-------------------------------------
AssemblyInfo.cpp
---------------------
#include "stdafx.h"
using namespace System::Reflection;
using namespace System::Runtime::CompilerServices;
//
// General Information about an assembly is controlled
through the following
// set of attributes. Change these attribute values to
modify the information
// associated with an assembly.
//
[assembly:AssemblyTitleAttribute("")];
[assembly:AssemblyDescriptionAttribute("")];
[assembly:AssemblyConfigurationAttribute("")];
[assembly:AssemblyCompanyAttribute("")];
[assembly:AssemblyProductAttribute("")];
[assembly:AssemblyCopyrightAttribute("")];
[assembly:AssemblyTrademarkAttribute("")];
[assembly:AssemblyCultureAttribute("")];
//
// Version information for an assembly consists of the
following four values:
//
// Major Version
// Minor Version
// Build Number
// Revision
//
// You can specify all the value or you can default the
Revision and Build Numbers
// by using the '*' as shown below:
[assembly:AssemblyVersionAttribute("1.0.*")];
//
// In order to sign your assembly you must specify a key
to use. Refer to the
// Microsoft .NET Framework documentation for more
information on assembly signing.
//
// Use the attributes below to control which key is used
for signing.
//
// Notes:
// (*) If no key is specified, the assembly is not
signed.
// (*) KeyName refers to a key that has been installed
in the Crypto Service
// Provider (CSP) on your machine. KeyFile refers
to a file which contains
// a key.
// (*) If the KeyFile and the KeyName values are both
specified, the
// following processing occurs:
// (1) If the KeyName can be found in the CSP, that
key is used.
// (2) If the KeyName does not exist and the
KeyFile does exist, the key
// in the KeyFile is installed into the CSP and
used.
// (*) In order to create a KeyFile, you can use the
sn.exe (Strong Name) utility.
// When specifying the KeyFile, the location of
the KeyFile should be
// relative to the project directory.
// (*) Delay Signing is an advanced option - see the
Microsoft .NET Framework
// documentation for more information on this.

[assembly:AssemblyDelaySignAttribute(false)];
[assembly:AssemblyKeyFileAttribute("")];
[assembly:AssemblyKeyNameAttribute("")];
