ASP.NET 2.x or 3.x need to change to below json.

{
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "profiles": {
    "Watch": {
      "executablePath": "dotnet.exe",
      "workingDirectory": "$(ProjectDir)",
      "commandLineArgs": "watch run",
      "launchBrowser": true,
      "launchUrl": "http://localhost:5000/",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
