I am just trying to figure out how to change the port when I launch the debugger. Right now it launches with 5000 by default.

Here is an example of the launch setting where I would like to change the port.

{
   "version": "0.2.0",
   "configurations": [
        {
            "name": ".NET Core Launch (web)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            // If you have changed target frameworks, make sure to update the program path.
            "program": "${workspaceRoot}/bin/Debug/netcoreapp2.0/Ambassadors.Admin.Web.dll",
            "args": [],
            "cwd": "${workspaceRoot}",
            "stopAtEntry": false,
            "internalConsoleOptions": "openOnSessionStart",
            "launchBrowser": {
                "enabled": true,
                "args": "${auto-detect-url}",
                "windows": {
                    "command": "cmd.exe",
                    "args": "/C start ${auto-detect-url}"
                },
                "osx": {
                    "command": "open"
                },
                "linux": {
                    "command": "xdg-open"
                }
            },
            "env": {
                "ASPNETCORE_ENVIRONMENT": "Development"
            },
            "sourceFileMap": {
                "/Views": "${workspaceRoot}/Views"
            }
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach",
            "processId": "${command:pickProcess}"
        }
    ]
}

This isn't really a C# extension question but rather an ASP.NET question. So you may have better luck asking the question on an ASP.NET repo.

your project should have a launchSettings.json file similar to this one:

  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:12345/",
      "sslPort": 0
    }
  },

There will be entries for iis, Project, etc. The applicationUrl will configure the port that is used by the app.

This page has some details regarding the launchSettings file. If you don't find the answer you're looking for, I'd open an issue on https://github.com/aspnet/home.

launchSettings.json is not read when launching with vscode (using launch.json). Environment variable ASPNETCORE_URLS should be used instead:

"env": {
    "ASPNETCORE_ENVIRONMENT": "Development",
    "ASPNETCORE_URLS": "http://localhost:4000/"
}
