Base class for controllers

[fasteddys]

Can you add some baseControllers and extensions

public class BaseController<T> : Controller where T : Controller
{
    private IBreadCrumbService _breadCrumbInstance;
    private INotyfService _toastInstance;
    private ILogger _loggerInstance;

    protected INotyfService _toast => _toastInstance ??= HttpContext.RequestServices.GetService<INotyfService>();
    protected IBreadCrumbService _breadcrumbs =>
        _breadCrumbInstance ??= HttpContext.RequestServices.GetService<IBreadCrumbService>();
    protected ILogger _logger => _loggerInstance ??= HttpContext.RequestServices.GetService<ILogger<T>>();
}
