• The GetProviderKeyLookupServiceAsync method should check if the service is available before returning it. Currently, it returns unavailable services, which is inconsistent with GetProviderKeyLookupServicesAsync (which filters by availability). This could allow callers to obtain and use a service that returns false from IsAvailableAsync(). Consider adding an availability check or throwing an exception if the requested service exists but is not available in the current context.

    public virtual  Task<IResourcePermissionProviderKeyLookupService> GetProviderKeyLookupServiceAsync(string serviceName)
    {
        var service = _lazyProviderKeyLookupServices.Value.FirstOrDefault(s => s.Name == serviceName);
        return service == null
            ? throw new AbpException("Unknown resource permission provider key lookup service: " + serviceName)
            : Task.FromResult(service);
    }

• Adding IsAvailableAsync() to this public interface is a breaking change for any external implementations of IResourcePermissionProviderKeyLookupService. If maintaining compatibility matters, consider a new optional interface for availability (checked via is pattern) so existing implementations continue to work and default to available.

public interface IResourcePermissionProviderKeyLookupService
{
    public string Name { get; }

    Task<bool> IsAvailableAsync();

    public ILocalizableString DisplayName { get; }

    Task<List<ResourcePermissionProviderKeyInfo>> SearchAsync(string filter = null, int page = 1, CancellationToken cancellationToken = default);

    Task<List<ResourcePermissionProviderKeyInfo>> SearchAsync(string[] keys, CancellationToken cancellationToken = default);
