Where to specify localhost port in VS Code

I am building an ASP.NET Core app and am wanting to use a specific port when launching debug in VS Code. It defaults to running http:// localhost:5000. I am unable to find any setting for where I would change this. When I try to specify a port setting in the launch.json file, I am being alerted that it is not allowed. Is there a specific setting to set for specifying which port?

You can define any port number in the launch.json file like below (Reference code taken for Django application run)

       "args": [
            "runserver", "3300",
        ],

You can configure this from the launch.json file. You want to find the "env" property and add 

"ASPNETCORE_URLS":"http://localhost:<PORT_NUMBER>"

Adjusting from the default launch.json it should look something like this:

"env": {
     "ASPNETCORE_ENVIRONMENT": "Development",
     "ASPNETCORE_URLS":"http://localhost:5001"
},

This way your port change will only affect your locally running application and you won't be adding debugging code to your production application

Do you have to remove this when you deploy to staging or production? This doesnt seem good for anything but local dev.

In your Program.cs

try to add .UseUrls("http://localhost:5050")

Port number can be anything other than the specified one
