I am working with asp.net core mvc application in which, when I have created project at that time I have choosen no authentication as authentication type. but now I need to use individual authentication for standard functionalities like register, login, forgot password, email verification and all.
problem is I have completed half of development and can't start now from beginning. so need to change authentication type in my existing project.
is there any way to update authentication in existing .net core application.
