ASP.NET Core routing works in VS IIS Express but not in IIS 10

I am developing ASP.NET Core web api. here i have a situation like i have to use multiple get functions which get data from sql server db. So for that i'm doing custom attribute routes. below are my codes

[Route("api/[controller]")]
public class MeController : Controller
{
    private readonly ITechRepository _tech;
    private readonly IPageOptions _page;
    public MeController(ITechRepository tech,IPageOptions page)
    {
        _tech = tech;
        _page = page;
    }

   [Route("getTech")]
    public IEnumerable<TechStack> Get()
    {
        return _tech.getAll();
    }
    [Route("getOptions")]
    public IEnumerable<PageControl> getOptions()
    {
        return _page.getOptions();
    }
     //GET api/values/5
    [HttpGet("{id}")]
    public int Get(int id)
    {
        return id;
    }
}

The above routes are works well in VS IIS Express and this is that url http://localhost:51889/api/me/gettech

But when i publish this api in IIS 10. The getTech and getOptions were not working it producing 404 error and also [HttpGet("{id}")] is working in both.

Can anybody help on this...
