In .NET 8, I've got a shared Razor component library, here I'm using Blazored localstorage to store and read the session information. That's because the application needs to run offline.
For this purpose, I need a way to verify, that the JWT token exists and the expiry date is greater than now, if that's the case, I want to skip the login page. Also if I'm visiting any of the pages under /, but I'm not authenticated, I want to be redirected to the login page.
Also I want to use the authorize attribute on some pages that should only be available to specific user roles.
How is this possible? I've created a CustomAuthenticationStateProvider, but my breakpoint is never reached.
If I'm using the authorize attribute I'm getting an error. If I'm creating a CustomAuthenticationHandler, the error disappears, but the handling doesn't work like expected, if I'm referencing the CustomAuthenticationStateProvider in my CustomAuthenticationHandler, I'm getting a java interop failure, so I don't know if this all is the right way at all, because on some websites I'm reading that localstorage cant be accessed at a middleware like point.
As I only know middleware in the backend, I don't know if this is the case. Also I'm not using prerender!
