# New Pattern Submission — sam-dotnet-responsestreaming-bedrock

## Pattern Details

- **Title:** Lambda Response Streaming with Amazon Bedrock — Story Generator (.NET)
- **Description:** Stream LLM-generated story text token-by-token from Amazon Bedrock through Lambda response streaming and API Gateway to the client.
- **Language:** .NET (C#)
- **Framework:** SAM
- **Level:** 200
- **Services:** AWS Lambda, Amazon API Gateway, Amazon Bedrock

## How It Works

This pattern deploys a Lambda function that invokes Amazon Bedrock (Claude Sonnet) via the ConverseStream API and pipes generated tokens directly through API Gateway response streaming to the client.

The user specifies a genre, setting, and theme via query parameters, and the story appears word-by-word in the terminal. First tokens arrive within seconds — no waiting for the full generation to complete.

This demonstrates end-to-end streaming from Bedrock through Lambda to the client using the .NET response streaming SDK (LambdaResponseStreamFactory.CreateHttpStream).

Inizia con la PR #3236 collegata, che contiene il modello, e verifica l’entry point della funzione Lambda e la relativa configurazione di deployment SAM. Il lavoro è completato quando il pattern dimostra lo streaming delle risposte .NET da Amazon Bedrock attraverso API Gateway fino al client, come descritto.
