# Microsoft Shipped an Agent Framework for Go — the Go Field We Mapped Last Week Just Got a Vendor Heavyweight

> A day after we argued Go teams rarely need an agent framework, Microsoft put a first-party one into public preview. Here's what it covers, what it's still missing, and when a founder should reach for it instead of a forty-line loop.

## Key takeaways

- Microsoft put Microsoft Agent Framework for Go into public preview on July 10, 2026 — a Go implementation of the same framework that already ships for .NET and Python, installable with `go get github.com/microsoft/agent-framework-go` and requiring Go 1.25 or later.
- The Go SDK covers the core surface: agents, tools, middleware, multi-agent workflows, observability, and interoperability integrations — enough to build and orchestrate an agent in a Go service, CLI, or worker without a Python sidecar.
- It is explicitly preview and behind the other SDKs: declarative agents, RAG, CodeAct, and functional workflows are not yet implemented in Go, .NET still has broader product integrations, and the Go code is 'evolving outside the core upstream codebase' for now — so pin versions and expect churn.
- This matters because it lands in a field we mapped one day earlier: Eino, LangChainGo, and Google's Genkit Go (already 1.0 GA) were the Go options, and the honest fourth option was no framework at all. Microsoft's entry adds a vendor-backed heavyweight — most compelling if you're already on Azure AI Foundry and want first-party agents in the language your backend already speaks.

## At a glance

| Go agent option | What you're buying | Maturity (July 2026) | Best fit |
| --- | --- | --- | --- |
| No framework (for loop) | Nothing — Go's runtime already gives goroutines + context cancellation | Your code | Single model, a handful of tools, straight-line control flow |
| Microsoft Agent Framework for Go | First-party agents, tools, middleware, workflows, observability + Azure AI Foundry integration | Public preview (July 10), Go 1.25+, outside core upstream repo | You're on Azure/Foundry and want vendor-backed agents in Go |
| Genkit Go | Flows, local dev UI, built-in OpenTelemetry; Agents API in preview | 1.0 GA (stable API); Go ahead of Genkit's own Python (Beta) | Free observability + JS/Go parity, human-in-the-loop turns |
| Eino (ByteDance) | Graph/workflow orchestration + typed components + ReAct/DeepAgent | ~12k stars, Apache-2.0, active | Branching, stateful, human-in-the-loop graphs |
| LangChainGo | Broadest provider + vector-store integrations | ~9k stars, pre-1.0 | Reaching a backend you don't want to hand-write |

## By the numbers

- **July 10, 2026** — public-preview date for Microsoft Agent Framework for Go — one day after the Go framework field looked settled
- **Go 1.25+** — minimum Go version the SDK requires
- **4** — major capabilities not yet in the Go SDK — declarative agents, RAG, CodeAct, and functional workflows
- **3** — first-party language SDKs Microsoft Agent Framework now spans: .NET, Python, and Go

Last week we mapped the Go agent-framework field and reached an uncomfortable conclusion for anyone shopping for one: in Go, the honest fourth option is **no framework at all**. Goroutines give you parallel tool-call fan-out, `context.Context` gives you one deadline that severs a whole run, and the core agent loop lands in about forty lines — so Eino, LangChainGo, and Genkit Go were things you adopted for *orchestration or tracing*, not because Go left a hole a Python framework fills.
**One day after that piece ran, Microsoft dropped a first-party framework into the field.** On **July 10, 2026**, Microsoft put **Microsoft [Agent Framework](/topics/agent-frameworks) for Go** into public preview — a Go implementation of the same framework already shipping for .NET and Python. If you skimmed nothing else: it's real, it's `go get github.com/microsoft/agent-framework-go`, it needs **Go 1.25+**, and it is emphatically **preview**.
What it is, in one screen
Microsoft Agent Framework is Microsoft's merged successor to Semantic [Kernel](/stack/kernel) and [AutoGen](/stack/autogen) — the .NET/Python framework for building and orchestrating agents and multi-agent workflows. The Go SDK brings that same shape to Go developers building **services, CLIs, workers, and cloud-native apps** where Go is already the natural fit, so you no longer have to run a Python sidecar just to host an agent.
The Go preview covers the **core surface**:
- **Agents** — created through providers (e.g. `foundryprovider.NewAgent(...)`, configured with an endpoint and model via environment variables, then run with `a.RunText(context.Background(), ...)`).
- **Tools** — function calling wired into the agent loop.
- **Middleware** — cross-cutting hooks around agent and tool calls.
- **Workflows** — multi-agent orchestration.
- **Observability** — tracing/telemetry hooks.
- **Interoperability** — integrations with the wider Microsoft agent ecosystem, including Azure AI Foundry.

That's enough to build and orchestrate an agent end-to-end in Go today.
What it is *not* yet
This is the part a founder has to read before betting on it. As of the preview, the Go SDK **trails .NET and Python**:
- **Declarative agents, RAG, CodeAct, and functional workflows are not yet implemented** in Go.
- **.NET still has broader product integrations** and several features Go hasn't reached.
- The Go code is **"evolving outside the core upstream codebase"** — which means it moves faster and carries looser stability guarantees than the main framework. **Pin your version** and read the release notes before every upgrade.

So this is a preview in the literal sense: the skeleton and the happy path are there; the batteries that make the .NET SDK a production default are not all in the box yet.
Where it sits in the Go field
Nothing about Microsoft's entry changes the underlying truth from [last week's Go framework map](/posts/golang-ai-agent-framework-eino-vs-langchaingo.html): for a single model and a handful of tools, a hand-rolled loop is still the correct amount of code, because Go's runtime already gives you the concurrency and cancellation a framework exists to mediate. What Microsoft adds is a **vendor-backed heavyweight** to the list of reasons you'd adopt one anyway:
- **Reach for Microsoft Agent Framework for Go** if you're already invested in **Azure AI Foundry** and want first-party agents in the language your backend speaks — accepting preview-grade churn.
- **Reach for [Genkit Go](/posts/golang-ai-agent-framework-eino-vs-langchaingo.html)** if you want a **stable 1.0 API and built-in OpenTelemetry tracing** today. Notably, Genkit's Go support is *ahead of its own Python* (which is still Beta) — Go is not the afterthought here.
- **Reach for Eino** if your control flow is a genuine **graph** with branches, loops, and human-in-the-loop interrupts.
- **Reach for no framework** if your agent is a straight line. Still the default.

Why two clouds backing Go is the actual signal
The agent-SDK conversation has been Python- and TypeScript-first, and [OpenAI and Anthropic still lead there](/posts/2026-07-13-founder-shipping-log-agent-frameworks-q2.html). Microsoft shipping a Go SDK — right alongside Google's Genkit Go, already 1.0 GA — is the two hyperscalers with the deepest cloud-native footprints saying the same thing: **the language your infrastructure is already written in is now a first-class place to run agents.** For a founder whose stack is Go, that removes the last easy excuse to bolt on a Python service. For everyone else, it's a reminder that "which agent framework" increasingly has a *which language* question underneath it — and the answer is no longer automatically Python.
**The founder move this week:** if you run Go and you're on Azure, `go get` the preview and prototype one agent against it — but keep the forty-line loop in your back pocket, because for most single-model agents it's still the honest answer. If you're not on Azure, Genkit Go is the more finished Go story today, and Eino is the pick when you need real graph orchestration.

## FAQ

### What is Microsoft Agent Framework for Go and when did it ship?

It's a Go implementation of Microsoft Agent Framework — the same agent-and-workflow framework Microsoft already ships for .NET and Python — released as a public preview on July 10, 2026. It brings the framework's core concepts (agents, tools, middleware, multi-agent workflows, observability, interoperability) to Go services, CLIs, workers, and cloud-native apps, so Go teams can build agents without standing up a separate Python process.

### How do I install it and what are the requirements?

Add it with `go get github.com/microsoft/agent-framework-go` (Microsoft's getting-started also pulls `github.com/github/copilot-sdk/go`), and it requires Go 1.25 or later. A minimal agent is created through a provider — for example `foundryprovider.NewAgent(...)` configured with your endpoint and model via environment variables — and run with `a.RunText(context.Background(), ...)`.

### What's missing compared to the .NET and Python SDKs?

Several things. As of the preview, declarative agents, RAG, CodeAct, and functional workflows are not yet implemented in Go, and .NET has broader product integrations and features the Go SDK hasn't reached. Microsoft also notes the Go implementation is currently 'evolving outside the core upstream codebase,' which means faster movement and looser stability guarantees — pin your version and read the release notes before you upgrade.

### Should I switch from Eino, Genkit Go, or a hand-rolled loop?

Only for a reason. If your control flow is a single model with a few tools, Go's goroutines and `context.Context` already give you the concurrency and cancellation a framework mostly exists to supply — a hand-written loop stays the right amount of code. Reach for Microsoft Agent Framework for Go when you're already invested in Azure AI Foundry and want first-party agents in Go; reach for Genkit Go when you want a stable API and built-in tracing today; reach for Eino when you need real graph orchestration. Treat Microsoft's SDK as preview: prototype on it, don't bet a production launch on the unfinished surface yet.

### Why does it matter that Microsoft (and Google) are backing Go for agents?

Because the agent SDK conversation has been Python- and TypeScript-first, and OpenAI and Anthropic still lead there. Microsoft shipping a Go SDK — alongside Google's Genkit Go, which is already 1.0 GA and whose Go support is further along than Genkit's own Python — signals that the language your cloud-native backend is probably already written in is now a first-class place to run agents, not a second-class port you bolt a Python service onto.
