  I create a Managed C++ Application project in VS2002 and add code to _tmain, as shown below.
  
  ***********************
  // This is the main project file for VC++ application project
  // generated using an Application Wizard.
  
  #include "stdafx.h"
  
  #using <mscorlib.dll>
  #include <tchar.h>
  
  using namespace System;
  
  // This is the entry point for this application
  int _tmain(void)
  {
      Char ch = L'z';
      __box Char* bxChar = __box( ch );
      Char ch2 = *bxChar; //** causes NullReferenceException
      Console::WriteLine(ch1);
      return 0;
  }
  ***********************
  
  The unboxing operation causes a NullReferenceException.  I also tried using the casting operators in the offending line, and received the same error.  What am I missing?  Is there a known issue and/or workaround?
  
  Thanks in advance for any help.
