Module 10 — AgentCore concepts
Prompt & Tool Design for .NET Teams · Part 4 — AgentCore and Production · Module 10 of 12
No code this time: read, watch, and reframe. AgentCore is Amazon Web Services’ (AWS) name for five things you have almost certainly already built worse versions of: somewhere to run the agent, a way to expose tools, somewhere to keep memory, an identity story, and observability. The value isn’t novelty; it’s not maintaining your own.
Objective
Understand the AgentCore primitives — Runtime, Gateway, Memory, Identity, Observability — and where each one replaces something you’d otherwise hand-roll.
Read and watch (~25 min)
- The AgentCore product overview.
- The AgentCore docs landing page; skim the service map.
- A video: search YouTube for “AgentCore deep dive re:Invent” and pick the most recent official AWS session. Keep it to something six months old or newer. This service moves fast enough that older talks describe a different product.
The reframe that matters for a .NET team
Two things to take away, because they’re the bits AWS’s Python-heavy examples bury:
- Runtime hosts containers that speak an HTTP contract. A .NET service is a first-class citizen here, regardless of what the sample repo’s file extensions imply.
- Gateway turns ordinary APIs and Lambdas into agent-ready tools. This is why you don’t need to learn to write a Model Context Protocol (MCP) server to get started. The Gateway does that translation for you. (Module 11 puts this into practice.)
Done when
You can name, for at least one primitive, a system you’ve built before that it would replace or remove. “Memory replaces the session store you’d otherwise stand up and maintain yourself” is the level of concrete you’re after.
