## AuthenticationController Class

Handles authentication\-related processes in the context of OpenID Connect and OAuth2 protocols\.
This controller manages user authorization, provides user information, handles end\-session requests,
and checks session statuses\.

```csharp
public sealed class AuthenticationController : Microsoft.AspNetCore.Mvc.ControllerBase
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → [Microsoft\.AspNetCore\.Mvc\.ControllerBase](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.mvc.controllerbase 'Microsoft\.AspNetCore\.Mvc\.ControllerBase') → AuthenticationController

### Remarks
This controller serves as the core component for managing user authentication and session control
in an OpenID Connect compliant manner\. It includes endpoints for initiating user authorization,
retrieving authenticated user information, managing user logout processes, and checking the status
of user sessions for OIDC compliance\.
