title: How can I add a C# GUI to C++ code?
body: <p>I wrote C++ code in which are included some libraries and defined some functions plus the main. I am trying to add a GUI to this code in C#.</p>
  
  <p>This code sends data (<code>double[]</code>) to a server. What I would make is create a graphic user interface using C#, that lets me to start sending data, clicking a button.</p>
  
  <p>How could I make this?</p>
