Why do we check to see if a claimsPrincipal.Identity is ClaimsIdentity?

[VictorioBerra]

Blazor.BFF.OpenIDConnect.Template/BlazorBffOpenIdConnect/Server/Controllers/UserController.cs

Line 26 in 5bea24e

if (claimsPrincipal?.Identity is ClaimsIdentity claimsIdentity)

What purpose does this serve? When would it NOT be a ClaimsIdentity?

Thank you

@VictorioBerra I think I had a null problem here, but this does look strange. I need to verify and fix maybe.

Thanks for the feedback
