Self contained web API run exe from cmd

Question

Hello,
I've got a self hosted web API which runs in a console, is there anyway I can run this console exe from command prompt and specify a port number to run from as an argument ? & If you can what would the command look like & do I need to change anything in my project to allow for this ?

It’s up to use to decide. The command line arg are passed to the main. Common convent is if want it as an option it’s

   -<single letter>:<value>
   —<multiple letters>:<value>
say

    myapp -p:8080

    myapp —port:8080

You of course write a simple parser and pass the value to the port declaration code.

note: all asp.net core webapi apps are command line apps. See program.cs to access args
