Why does 'IIS on the server' behave differently than 'Local IIS' and 'IIS Express'? (ASP.NET Core + Angular + Windows Authentication)

If I create an ASP.NET Core + Angular project and enable Windows Authentication (following these instructions link) and debug it using IIS Express, why does the Angular app load if I open the browser with a local user (runas /user:MY-PC\local-user Chrome.exe) which is not in AD? Shouldn't IIS Express ask me for credentials?
If I publish to Local IIS (with Windows Authentication enabled and Windows Hosting Bundle installed) using Web Deploy I get the same result, Angular app loads and Local IIS does not ask for credentials. I tried splitting the project with ASP.NET Core API + Angular, but I got the same result. I had to implement an endpoint with some logic to return 401 (not network user), 403 (network user but not in my AD Group) and a Guard in Angular to avoid loading the Component and 401 and 403 pages.
However, when I did publish to IIS on the server (manually, I created the website and copied the files, and installed Windows Hosting Bundle), I realized the behavior is different, the Angular app is not loaded and IIS always asks for credentials. If I put wrong credentials or click on Cancel, IIS shows 401. With the correct credentials I can access and browser will remember them, but if I close and open the browser again, I need to re-enter my credentials, which is a bit annoying.
IIS Express and Local IIS never ask me for credentials when I open a normal browser (using my AD account).

Q: How to remove login in IIS Application

I've inherited an old asp.net application which runs on IIS v10, but I've run into a problem trying to remove the authentication. The application runs under the Default Web Site. It was originally set to Windows Authentication and worked, but now I need to remove the login that occurs on load of the website.
The Default Web Site (app parent) authentication is set to Anonymous. When I disable all authentication at the application level, I get a 401 - Unauthorized User error in the browser. When I enable Anonymous authentication, the site loads very slow, but only the HTML with none of the CSS styling. I'm not sure why this is.
How should the authentication be configured to remove a login?
You need to choose the application which under the Default Web Site and click the Authentication module.
In addition to disabling windows authentication, also enable anonymous authentication.
If you want to disable windows authentication for a file in the application, first select the content view to view the files inside the application, then select the file and right-click the switch to features view.

Authentification with Windows Auth NTLM

There is a WebAPI hosted in IIS. It is using Windows authentification with NTLM protocol only. If I am trying to reach it with chrome extension which gives me the ability to send REST requests, chrome prompts me for credentials and this is the part I dont understand why? Windows auth is the one that should take my information from my windows login isnt it? It is not forms auth. Of course it happens the first time only, if you are reaching it multiple times it just returns the token, but I guess its just the session things.
I feel that I am missing something and dont have enough knowledge about it so any information would be nice.
Question:
Why windows auth is prompting for credentials when I am trying to authenticate to my WebAPI the first time? Shouldnt it handle this automatically based on my windows login information?
Thank you
Windows authentication means it will validate the username and password of the user available in the directory listing of the hosted server.
And after you enter the credentials once then the browser will manage it further.
If you close that tab and open the url in new tab then also it will not prompt again unless the browser is not closed and reopened.
It is not possible to handle windows login automatically without login prompt box.

Bypass windows Aunthentication

We have developed a MVC Application and it's Windows Authentication enabled,
(Web.config - AuthenticationMode="Windows").
But we have requirement where a set of pages need to be behaved as Anonymous aunthentication.
Since a web.config is pointed to Windows Authentication , Our application is always prompting Domain user Name & Password when user access to any pages.
We have tried CustomAuthorize & IAunthenticationFilter to bypass the windows Authentication But it is still prompting the User Name and Password.
Is there any way to Implement Anonymous Authentication for few pages/Controllers while rest of the pages/controllers running in the windows Authentication Mode ?
Or
Is there any way to feed the Domain user id and Password programatically ?

Authentication Require Enter username and password to http://www

I am getting window authentication window popup on some of my views in mvc4. It works fine when I host it on local server. But when I upload my code to my hosting server, all the views works fine except some views.
I am using form authentication in my application. And the views which given me such popups their controller class define with [Authorize] attribute. Is it an issue with IIS on hosted server or something else?
This is the popup message:
I suspect that you have Integrated Windows Authentication or Basic Authentication configured in IIS for your website or application (depending on how you are hosting it). Make sure you disable it and enable anonymous access to the website if you want to use Forms Authentication.
Open IIS Manager and navigate to your website or application.
In Features View, double-click Authentication.
On the Authentication page, disable Windows authentication and enable Anonymous authentication.
