public class OrderService(ResiliencePipelineProvider<string> pipelineProvider)
{
 public async Task<Order> GetOrderAsync(string id, CancellationToken ct)
 {
 var pipeline = pipelineProvider.GetPipeline(
 PervaxisResiliencePipelineNames.Default);

 return await pipeline.ExecuteAsync(
 async token => await _repository.GetByIdAsync(id, token), ct);
 }
}

Pipeline Names

// Use constants — never hardcode strings
PervaxisResiliencePipelineNames.Default // "pervaxis-default"
PervaxisResiliencePipelineNames.Messaging // "pervaxis-messaging"
PervaxisResiliencePipelineNames.Http // "pervaxis-http"
