The type or namespace name 'ApiController' could not be found - Nuget is installed

FrameWork : .Net Framework 4.7.2.

Web api project:After pull code from git (worked and compiled on a different local machine), and trying to build,getting:

**The type or namespace name 'ApiController' could not be found (are you missing a using directive or an assembly reference?)**

regarding all apiController inherited class attributes and keywords :ApiController, HttpPost, FromBody, etc.),

using System;using System.Collections.Generic;using System.Net.Http;using System.Web.Http;namespace POC_Book_Api.Controllers{    public class MyController : ApiController    {        [HttpPost]        public void Post([FromBody] SomeCollection items)

System.Web Assembly is referenced in the project References.Nuget Microsoft.AspNet.Api is installed and updated in the project.

What am I missing here ?
