There is another way to implement this right from startup. It is not exact solution to this case per se, but I modified it to suit my need. We need a singleton for this. This is a startup class with environment injection.

namespace www
{
    public class Startup
    {
        private IHostingEnvironment _env;

        public Startup(IHostingEnvironment env)
        {
            _env = env;
            Environment.rootPath = env.WebRootPath;
        }

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
        }

        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseStaticFiles();
            app.UseMvc();
        }
    }
}

The environment variables I was looking for is there, IHOstingEnvironment. But for my purpose, I need to make Environment class like this to easily access all environment items from all project. This singleton will provide data to configuration, environment, and many other thing. But for this thread, I would just put one rootPath property.

namespace www.Utilities
{
    public class Environment
    {
        private static Environment instance;
        private static String _rootPath;

        private Environment() { }

        public static Environment Instance
        {
            get
            {
                if (instance == null)
                {
                    instance = new Environment();
                }
                return instance;
            }
        }

        public static string rootPath
        {
            set
            {
                _rootPath = value;
            }
            get
            {
                return _rootPath;
            }
        }    
    }
}

As I have accepted Oluwafemi's answers, I'll keep it that way, since he led me to this. But I think this is the better way to access environment variables throughout the project
