api/values 404 not found localhost - ASP.NET Core

I am perplexed as to why my Web API straight out of the box is not working locally. I have created a new Web Api in Visual Studio 2017 .NET core, here is the controller:

namespace WebAPICore.Controllers
{
    [Route("api/[controller]")]
    public class ValuesController : Controller
    {
        // GET api/values
        [HttpGet]
        public IEnumerable<string> Get()
        {
            return new string[] { "Hello", "Hello 2" };
        }

        // GET api/values/5
        [HttpGet("{id}")]
        public string Get(int id)
        {
            return "value";
        }

        // POST api/values
        [HttpPost]
        public void Post([FromBody]string value)
        {
        }

        // PUT api/values/5
        [HttpPut("{id}")]
        public void Put(int id, [FromBody]string value)
        {
        }

        // DELETE api/values/5
        [HttpDelete("{id}")]
        public void Delete(int id)
        {
        }
    }
}

I am running via IIS as webapicore.local/ so I am trying webapicore.local/api/values in the browser and I am getting a 404! It is also not working with Postman:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

legend{color:#333333;;margin:4px 0 8px -12px;_margin-top:0px; 
font-weight:bold;font-size:1em;} 
..............

Any ideas?

Try the same route but using the default port number 5000: webapicore.local:5000/api/values. This is assuming you haven't overridden the default application url in launchSettings.json.

I have never seen webapicore.local/, but if that is not necessary for your project, look in the autogenerated Properties/launchSettings.json file. Mine looks like this after creating a new web application project: 

{
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false, 
    "anonymousAuthentication": true, 
    "iisExpress": {
      "applicationUrl": "http://localhost:59313",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "api/values",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "WebApplication1": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "api/values",
      "applicationUrl": "https://localhost:5001;http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

After launching with IIS navigate to https://localhost:59313/api/values, and it should work right out of the box.

Again though, if webapicore.local/ is necessary for your project this may not be your solution.
