/*
 *  C++\CLI code will not compile if it attempts to use a C++11 thread.
 *  You need to isolate the threaded code behind an interface and
 *  object factory in native C++ (don't compile with /CLR option).  
 *  
 *  Then package that component as a DLL and have the C++\CLI code make
 *  a reference to the DLL.  Now it will compile and run.
 *
 *  This code shows you how to do that.  Compile the C++\CLI code with
 *  the /clr option set in the General Project Properties.  Make sure
 *  that it has a reference to the native DLL and includes the DLL Lib file.
 *
 *  Use the dll protocol shown in Comm.cpp and compile without /CLR option.
 *  Now you can build and run the project.
