You can examine the registery keys of other file extensions to learn how that works. — jtxkopt, Jan 18 '22 at 11:58

You can use Setup Wizard, in it you can change the parameter that is responsible for the file extension belonging to your program.

i dont have this panels you have, how did you do that ? – mahdi noroozi Jan 19 '22 at 06:21
@mahdi-noroozi, in the _Solution Explorer_, you need to select (make active) the project created using the **Setup Wizard**. After that, you will have the wizard project management buttons on the top panel. – Hopex Development Jan 26 '22 at 18:35
