Build enterprise agents for Microsoft 365, Teams, and Copilot Studio using the Microsoft Agents SDK with aiohttp hosting, AgentApplication routing, streaming responses, and MSAL-based authentication. Use the microsoft-docs MCP to verify the latest API signatures for AgentApplication, startagentprocess, and authentication options. Confirm package versions on PyPI for the microsoft-agents-\ packages you plan to use. ⚠️ Breaking Change: Recent updates have changed the Python import structure from microsoft.agents to microsoftagents (using underscores instead of dots). 🔑 Two rules apply to every code sample below: 1. This SDK is async-first — use async def handlers and async with throughout. 2. Use explicit auth managers and context-managed network resources. Use MsalConnectionManager for agent auth, and wrap per-request HTTP resources in async with (for example, aiohttp.ClientSession). Snippets may abbreviate this setup, but production code should always follow both rules. 1. This SDK is async-first — use async def handlers and async with throughout. 2. Always use context managers for clients and async credentials. Wrap every client in with Client(...) as client: (sync) or async with
