ASP.NET MVC6 default debugging launch URL

refer to https://stackoverflow.com/questions/30002050/asp-net-mvc-6-default-debugging-launch-url

Q: When using the new Visual Studio 2015 RC ASP.NET 5.0 Web API template the default debugging start up URL is somehow set to api/values. Where is this default configured and how do I change it?

Ans:
    here was very little documentation that I could find regarding where this start up URL was declared. There is a brief mention of it in this blog post on MSDN. I eventually stumbled upon it in the launchSettings.json file under the Properties node of the project as shown below:

Here are the contents of this file:

{
  "profiles": {
    "IIS Express": {
      "commandName" : "IISExpress",
      "launchBrowser": true,
      "launchUrl": "api/values",
      "environmentVariables" : {
        "ASPNET_ENV": "Development"
      }
    }
  }
}

You can change the launchURL to your desired default route.
