+# Using SharePoint Grounding with AI Agents
+
+This sample demonstrates how to use the SharePoint grounding tool with AI agents. The SharePoint grounding tool enables agents to search and retrieve information from SharePoint sites.
+
+## What this sample demonstrates
+
+- Creating agents with SharePoint grounding capabilities
+- Using AgentTool.CreateSharepointTool (MEAI abstraction)
+- Using native SDK SharePoint tools (PromptAgentDefinition)
+- Managing agent lifecycle (creation and deletion)
+
+## Prerequisites
+
+Before you begin, ensure you have the following prerequisites:
+
+- .NET 10 SDK or later
+- Azure Foundry service endpoint and deployment configured
+- Azure authentication configured for `DefaultAzureCredential` (for example, Azure CLI logged in with `az login`, environment variables, managed identity, or IDE sign-in)
+- A SharePoint project connection configured in Azure Foundry
+
+**Note**: This demo uses `DefaultAzureCredential` for authentication. This credential will try multiple authentication mechanisms in order (such as environment variables, managed identity, Azure CLI login, and IDE sign-in) and use the first one that works. A common option for local development is to sign in with the Azure CLI using `az login` and ensure you have access to the Azure Foundry resource. For more information, see the [Azure CLI documentation](https://learn.microsoft.com/cli/azure/authenticate-azure-cli-interactively) and the [DefaultAzureCredential documentation](https://learn.microsoft.com/dotnet/api/azure.identity.defaultazurecredential).
+
+Set the following environment variables:
+
+```powershell
+$env:AZURE_FOUNDRY_PROJECT_ENDPOINT="https://your-foundry-service.services.ai.azure.com/api/projects/your-foundry-project" # Replace with your Azure Foundry resource endpoint
+$env:AZURE_FOUNDRY_PROJECT_DEPLOYMENT_NAME="gpt-4o-mini"  # Optional, defaults to gpt-4o-mini
+$env:SHAREPOINT_PROJECT_CONNECTION_ID="your-sharepoint-connection-id"  # Required: SharePoint project connection ID
+```
+
+## Run the sample
+
+Navigate to the FoundryAgents sample directory and run:
+
+```powershell
+cd dotnet/samples/GettingStarted/FoundryAgents
+dotnet run --project .\FoundryAgents_Step22_SharePoint
+```
+
+## Expected behavior
+
+The sample will:
+
+1. Create two agents with SharePoint grounding capabilities:
+   - Option 1: Using AgentTool.CreateSharepointTool (MEAI abstraction)
+   - Option 2: Using native SDK SharePoint tools
+2. Run the agent with a query: "List the documents available in SharePoint"
+3. The agent will use SharePoint grounding to search and retrieve relevant documents
+4. Display the response and any grounding annotations
+5. Clean up resources by deleting both agents
