[Vuejs]-Current logged in user on IIS in Vue.js application

In my opinion, you could not get the windows user in vue js. if you want to get the windows user identity in .net core site you could use below code:

In ConfigureServices

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

In controller

private readonly IHttpContextAccessor _httpContextAccessor;

public HomeController(IHttpContextAccessor httpContextAccessor)
        {           
            _httpContextAccessor =  httpContextAccessor;
            string userName = _httpContextAccessor.HttpContext.User.Identity.Name;     
        }
