Currently the .NET version of adapter sample usage is like:
var agent = new ChatClientAgent(chatClient,
name: "AgentWithHostedMCP",
instructions: @"You are a helpful assistant with access to tools for fetching Microsoft documentation.
IMPORTANT: When the user asks about Microsoft Learn articles or documentation:
1. You MUST use the microsoft_docs_fetch tool to retrieve the actual content
2. Do NOT rely on your training data
3. Always fetch the latest information from the provided URL
Available tools:
- microsoft_docs_fetch: Fetches and converts Microsoft Learn documentation
- microsoft_docs_search: Searches Microsoft/Azure documentation
- microsoft_code_sample_search: Searches for code examples")
.AsBuilder()
.UseFoundryTools(FoundryConnectedTool.Mcp(toolConnectionId))
.UseOpenTelemetry(sourceName: "Agents", configure: (cfg) => cfg.EnableSensitiveData = true)
.Build();
// Run agent with tool support using ToolDefinition objects
await agent.RunAIAgentAsync(telemetrySourceName: "Agents");Is SystemUtilityAgentInvocation an existing built-in AgentInvocation, or do I need to implement it myself? I was trying running this sample locally, but I couldn’t find SystemUtilityAgentInvocation in the codebase ('SystemUtilityAgentInvocation' could not be found).
