Implement Azure AD authentication in ASP.Net

How to implement Azure AD authentication in asp.net project

I had an existing application where I would like to implement AD authentication using Azure.

I have gone through the article but most of them were given in .Net core or MVC or Web API.

I need it in ASP.NET I have a button on the page when user click on it will navigate to Microsoft site to enter his credentials.

Once after successful login it should redirect to asp.net application
