 **the same testmml_win.rb in the same system, ruby2.2 works, ruby2.6.3 failed!** 

 **below is the test ruby code:** 

 ```ruby 
 require `require 'fiddle' 
 require 'fiddle/import' 


 if ARGV.length < 1 
    puts "Missing libPath argument..." 
    puts "Usage:    ruby HostTest2.rb libPath" 
    puts "Sample: ruby HostTest2.rb /home/ProtocolAdapter/output" 
    exit 
 end    

 puts "Demo for invoke C# code from ruby..." 


 String libPath = ARGV[0] 
 if libPath[libPath.length - 1] != '\\' 
     libPath = libPath + '\\' 
 end 
 puts libPath 
 $libCoreCLR_so_path = libPath + "libhostprotocol.dll" 
 puts $libCoreCLR_so_path 


 module ProtocolTest 
     extend Fiddle::Importer 
     dlload $libCoreCLR_so_path 
	
     extern 'void Init(const char* libPath)' 
 end 

 ProtocolTest.Init(libPath); ProtocolTest.Init(libPath);` 
 ```
