Hi Venkat, context.Resource as AuthorizationFilterContext is coming as null, even it is decorated with and I have also injected in the service. Any idea why is giving null?

Dear sir, I don't know, It is possible to see you or not... But tonight I have seen you in my dream .

Since the SuperAdminHandler is somewhat generic and I could see it being reused elsewhere, do we need to specify that it inherits AuthorizationHandler<specific requirement class>. I see that it ties the handler to that requirement. But instead can change it to and add the requirement to the needed policy definitions?

Can you re-use Handlers for different Requirements? Say you have an "AdminHandler" that you use to determine who is an Admin. So you use that to handle a GetIntoArea1Requirement. But there is another Requirement GetIntoArea2Requirement that both Admin and another group can see - so you have to write another handler for the 'another group' - but is there a way to re-use the Admin Handler or do you have to write the same logic again as it pertains to a different Requirement??

In SuperAdminHandler, I placed a breakpoint to see whats going on
For super admins, the if condition does return true and the context.succeed is also run but for some reason it doesn't let the resource be accessed even though it succeeded. HasSucceeded property is still false even though im calling the succeed method on the context. I googled this and i didnt find any solutions.
This behavior persists only if im logged in as a super admin. This doesn't happen with admins. the context.succeed works for admins but not for super admin accounts. Any idea why? thanks.
