Microsoft OpenTelemetry Distro — Greenfield Setup

When to Use

• User asks to "add observability" or "add telemetry" to a .NET app
• User wants to set up Agent 365, Azure Monitor, or OTLP export
• User is starting a new agent project and needs tracing
• User asks about Microsoft.OpenTelemetry package

Procedure

1. Detect App Type

Scan the project to determine the app type:

• ASP.NET Core — has WebApplication.CreateBuilder() or IHostApplicationBuilder → use hosted pattern
• Console / Background Service — no web host, uses OpenTelemetrySdk.Create() → use console pattern
• Agent Framework — references Microsoft.Agents.Builder or Microsoft.Agents.AI → use Agent Framework pattern

2. Install Package
