I am working with Visual Studio 2019 (.net 4.7). My Visual project is based on MVC without webform and without Microsoft Identity.

I try to implement the mechanism of authentification and authorization because I want to use the atributes like [Authorize(Roles = "admins")] on my Controller/actions.

I dont want to use Microsoft Identity, EF and OWIN.

I started to implement form authentification, and I can get in all my code the current UserName with User.Identity.Name which has the same value as FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe) used in the login process.

I can store the roles in the field UserData inside the FormsAuthentication Ticket.

Now, I want to implement the roles in order to activate the Authorize attributes and to use the function User.IsInRole("***") all over in my code ;

Can someone help me ?
