title: Using .PYD file in C#?
body: <p>I am developing a program using C#, but I just figured out that what I am going to program is very very difficult in C# yet easy in Python. So what I want to do is make a <code>.PYD</code> file and use it in C# program, but I don't know how. I've been searching about it but I couldn't find anything. </p>
  
  <p>So these are my questions: How do I use <code>.PYD</code> file in C#? I know that <code>.PYD</code> files are similar to <code>.DLL</code> files, so are <code>.PYD</code> files still usable in computers that have no Python installed? </p>
