ASP.NET Core launchSettings.json does not launch browser

Question

I am using dotnet core version 2.1.200.

For my asp.net core application I have following launchSettings.json file:

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iis": {
      "applicationUrl": "http://localhost/Contoso.Web.Manager",
      "sslPort": 0
    },
    "iisExpress": {
      "applicationUrl": "http://localhost:64802/",
      "sslPort": 44337
    }
  },
  "profiles": {
    "dev": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "http://localhost.manager.contoso.com:5000/",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

when I run dotnet run --launch-profile dev this runs application fine in console, but does not open new browser window.

Am I missing something here?

You need applicationUrl and launchUrl, eg:

    "dev": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "/swagger/",
      "applicationUrl": "http://localhost.manager.contoso.com:5000/",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }

Seems like you should use "applicationUrl" instead of "launchUrl" in your dev profile.

"applicationUrl": "http://localhost.manager.contoso.com:5000/",
