Open file with association

I created a file editor in C #, and I can open files using the "Open" button on the toolbar, I also linked the correct file types to the program, so when I click on the file with the * .nlp extension, the program opens correctly, but the file itself does not open (which is quite logical, since I have not implemented it yet)

Now my question is, how do I implement such a thing? I want the file to be open and downloaded when I click on it.

(btw, the file is just plain text, so nothing special, and this is for windows, if that matters)

Windows file associations are stored and managed in the registry under HKEY_CLASSES_ROOT

HKEY_CLASSES_ROOT
   .nlp
      (Default) = YourProgID//can by anything you want
   YourProgID
      shell
         open
            command
               (Default) = yourapp.exe %1

, : %1 . , .

:

static void Main(string[] args)
{
   // args will contain your filename
}
