ASP.NET5

Hi all,
I developed asp.net mvc application ( no .NET Core ).
It uses WSFederationAuthenticationModule implementation with a custom db to authenticate user.

Now I have to add Azure Active Directory Authentication and at runtime I have to select which authentication method should I use.

Is it possible to do it? If yes how can I do it?

Thanks in advance,
Simone

What I have tried:

With .net core it is simple to do it but i'm not able to find a solution in ASP.NET MVC ( .NET Framework ).
