Removing Kestrel binding warning

This is an old question but you can resolve that conflict between launchSettings.json and appSettings.json with "externalUrlConfiguration": true

Kestrel configuration in appSettings.json:

"Kestrel": {
"EndpointDefaults": {
  "Protocols": "Http1AndHttp2"
},
"Endpoints": {
  "HTTPS": {
    "Url": "https://localhost:4433"
  }
}

And this is launchSettings.json content:

{
  "profiles": {
    "TestApplication": {
      "commandName": "Project",
      "launchBrowser": true,
      "externalUrlConfiguration": true, //add this line
      "applicationUrl": "https://localhost:5001",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}
