Unable to add global AuthorizeFilter when using scaffolded Identity pages in ASP.Net Core MVC application
Solution 1:
Global AuthorizeFilter apply on every methods of your project that means your login method too.
I guess your login page is the page where users are redirected to when they are not logged in. so what happen is :
I'm going to login page => login page needs authorization => redirect to login page => login page needs authorization => redirect to login page...
Your login method has to accept anonymous connection cause user is not logged in yet.
Add the attribute [AllowAnonymous] on your login method.
