.Net Core

For those who got here looking for this configuration in .Net core this resides in the lauchSettings.json. Just edit the port in the property "applicationUrl".

The file should look something like this:

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:53950/", //Here
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "index.html",
      "environmentVariables": {
        "Hosting:Environment": "Development"
      },
    }
  }
}

Or you can use the GUI by double clicking in the "Properties" of your project.

Note: I had to reopen VS to make it work.
