Asp.net core - Web Api on Class Library

Question

I am trying to make n-tier application where web api is kept on a different class library. I made a TestController controller class in a different class library and my code goes like this

using Microsoft.AspNetCore.Mvc;
using System;
using System.Collections.Generic;

namespace PkrUni.SMS.Api
{
    [ApiController]
    [Produces("application/json")]
    [Route("api/[controller]")]
    public class TestController : ControllerBase
    {
        public IEnumerable<string> Get()
        {
            return new string[] { "Chris", "Hadfield" };
        }
    }
}

Now my question is how can I access this web api on my main project. I had already added a reference to that class library on main project but it doesn't working. My api is not working. 404 Page Not Found error shows up while trying to access the api. This is my project structure.

What am I doing wrong please help me.

Perhaps this. The controllers are referenced, but the app doesn't know to look for controllers in any assembly but its own. — Scott Hannen

Why did you put the controllers in a separate project anyways? That's not really required for an N-Tier app. — mason

@mason Api controller are only on different project but mvc controller are in main project. Is it bad practice to have api controller in different class — Chris Hadfield

It's not necessarily bad. But what advantage does it give you? I can't think of any. And if it's making it harder to build/run your app....I think you should think of the positives and negatives of your approach and decide whether it's worth it. — mason

@mason Can you tell me how to call an web api without exposing it on network tab of browser. — Chris Hadfield

Try to install Microsoft.AspNetCore.Mvc package in the razor class library. And in startup.cs use:

services.AddMvc().AddApplicationPart(Assembly.Load(new AssemblyName("PkrUni.SMS.Area.Api")));

Refer to here.

I test your scenario by creating a asp.net core2.2 MVC project and razor class library without any problem. Below is my structure:
