+- **Orchestration Features**: Advanced orchestration patterns including GroupChat, Sequential, and Concurrent workflows are now available in both Python and .NET implementations. See the respective language documentation for examples.
 - **Privacy and Data Protection**: The framework allows for human participation in conversations between agents. It is important to ensure that user data and conversations are protected and that developers use appropriate measures to safeguard privacy.
 - **Accountability and Transparency**: The framework involves multiple agents conversing and collaborating, it is important to establish clear accountability and transparency mechanisms. Users should be able to understand and trace the decision-making process of the agents involved in order to ensure accountability and address any potential issues or biases.
 - **Security & unintended consequences**: The use of multi-agent conversations and automation in complex tasks may have unintended consequences. Especially, allowing agents to make changes in external environments through tool calls or function execution could pose significant risks. Developers should carefully consider the potential risks and ensure that appropriate safeguards are in place to prevent harm or negative outcomes, including keeping a human in the loop for decision making.

+# Polling for A2A Agent Task Completion
+
+This sample demonstrates how to poll for long-running task completion using continuation tokens with an A2A AI agent, following the background responses pattern.
+
+The sample:
+
+- Connects to an A2A agent server specified in the `A2A_AGENT_HOST` environment variable
+- Sends a request to the agent that may take time to complete
+- Polls the agent at regular intervals using continuation tokens until a final response is received
+- Displays the final result
+
+This pattern is useful when an AI model cannot complete a complex task in a single response and needs multiple rounds of processing.
+
+# Prerequisites
+
+Before you begin, ensure you have the following prerequisites:
+
+- .NET 10.0 SDK or later
+- An A2A agent server running and accessible via HTTP
+
+Set the following environment variable:
+
+```powershell

+
+The sample supports three deployment scenarios:
+
+1. **Anthropic Public API** - Direct connection to Anthropic's public API
+2. **Azure Foundry with API Key** - Anthropic models deployed through Azure Foundry using API key authentication
+3. **Azure Foundry with Azure CLI** - Anthropic models deployed through Azure Foundry using Azure CLI credentials
+
+## Prerequisites
+
+Before you begin, ensure you have the following prerequisites:
+
+- .NET 8.0 SDK or later
+
+### For Anthropic Public API
+
+- Anthropic API key
+
+Set the following environment variables:

+$env:ANTHROPIC_DEPLOYMENT_NAME="claude-haiku-4-5"  # Optional, defaults to claude-haiku-4-5
+```
+
+### For Azure Foundry with API Key
+
+- Azure Foundry service endpoint and deployment configured
+- Anthropic API key
+
+Set the following environment variables:
+
+```powershell
+$env:ANTHROPIC_RESOURCE="your-foundry-resource-name"  # Replace with your Azure Foundry resource name (subdomain before .services.ai.azure.com)

+# Creating an AIAgent with Google Gemini
+
+This sample demonstrates how to create an AIAgent using Google Gemini models as the underlying inference service.
+
+The sample showcases two different `IChatClient` implementations:
+
+1. **Google GenAI** - Using the official [Google.GenAI](https://www.nuget.org/packages/Google.GenAI) package
+2. **Mscc.GenerativeAI.Microsoft** - Using the community-driven [Mscc.GenerativeAI.Microsoft](https://www.nuget.org/packages/Mscc.GenerativeAI.Microsoft) package
+
+## Prerequisites
+
+Before you begin, ensure you have the following prerequisites:
+
+- .NET 10.0 SDK or later
+- Google AI Studio API key (get one at [Google AI Studio](https://aistudio.google.com/apikey))
+
+Set the following environment variables:

+## Package Options
+
+### Google GenAI (Official)
+
+The official Google GenAI package provides direct access to Google's Generative AI models. This sample uses an extension method to convert the Google client to an `IChatClient`.
+
+> [!NOTE]
+> Until PR [googleapis/dotnet-genai#81](https://github.com/googleapis/dotnet-genai/pull/81) is merged, this option requires the additional `GeminiChatClient.cs` and `GoogleGenAIExtensions.cs` files included in this sample.
+>
+> We appreciate any community push by liking and commenting in the above PR to get it merged and release as part of official Google GenAI package.
+
+### Mscc.GenerativeAI.Microsoft (Community)
+
+The community-driven Mscc.GenerativeAI.Microsoft package provides a ready-to-use `IChatClient` implementation for Google Gemini models through the `GeminiChatClient` class.

+# Using reasoning with Anthropic agents
+
+This sample demonstrates how to use extended thinking/reasoning capabilities with Anthropic Claude agents.
+
+## What this sample demonstrates
+
+- Creating an AI agent with Anthropic Claude extended thinking
+- Using reasoning capabilities for complex problem solving
+- Extracting thinking and response content from agent output
+- Managing agent lifecycle
+
+## Prerequisites
+
+Before you begin, ensure you have the following prerequisites:
+
+- .NET 8.0 SDK or later
+- Anthropic API key configured
+- Access to Anthropic Claude models with extended thinking support
+
+**Note**: This sample uses Anthropic Claude models with extended thinking. For more information, see [Anthropic documentation](https://docs.anthropic.com/).
+
+Set the following environment variables:
+
+```powershell
+$env:ANTHROPIC_API_KEY="your-anthropic-api-key"  # Replace with your Anthropic API key
+$env:ANTHROPIC_MODEL="your-anthropic-model"  # Replace with your Anthropic model
+```
+
+## Run the sample
+
+Navigate to the AgentWithAnthropic sample directory and run:
+
+```powershell
+cd dotnet\samples\GettingStarted\AgentWithAnthropic
+dotnet run --project .\Agent_Anthropic_Step02_Reasoning
+```
+
+## Expected behavior
+
+The sample will:
+
+1. Create an agent with Anthropic Claude extended thinking enabled
+2. Run the agent with a complex reasoning prompt
+3. Display the agent's thinking process
+4. Display the agent's final response
