Microsoft Joins Google in Adding Go Support for AI Agent Development

Go in cloud infrastructure

Go is the dominant language for cloud‑native development, used to implement container orchestration (Kubernetes), container runtimes (Docker), infrastructure‑as‑code tools (Terraform), CI/CD pipelines, and command‑line utilities. It is also the preferred language for building backend services.

Microsoft Agent Framework for Go

Microsoft launched the Agent Framework in October 2025 as an open‑source toolkit that unifies the earlier AutoGen and Semantic Kernel projects. A public release occurred in April 2026, with new production‑mode features (context management, human‑approval steps, the CodeAct fast tool‑call method, and multi‑agent hand‑off) announced at the Build conference in June 2026. The framework originally supported only .NET and Python; a public‑preview Go SDK was released in July 2026.

The Go SDK provides the same building blocks as the .NET and Python versions: support for large models from Microsoft Foundry, Azure OpenAI, Anthropic, and Gemini; tool‑call capability; MCP integration for connecting agents to external systems; and coordination of multiple agents to complete a task.

“Microsoft Agent Framework is designed for developers transitioning from single‑prompt calls to production‑grade agent systems. These agents can use tools, retain context, coordinate with other agents, stream results, and be observed and managed as part of real applications.” – Quim Muntal, senior software engineer, Microsoft

The SDK implements graph‑based workflow orchestration. Workflows can express conditional routing, invoke sub‑workflows, create checkpoints, and incorporate human‑in‑the‑loop review steps.

“This is production‑level orchestration, not a chat‑loop wrapper.” – Pratik Dhanave, AI engineer, Microsoft (LinkedIn post)

He also described the release as a milestone for Go engineers because the SDK brings native graph‑oriented orchestration to the Go ecosystem.

Google Agent Development Kit (ADK)

Google released its Agent Development Kit in April 2025, initially supporting only Python. Go support was added in November 2025, and a full 1.0 version was released in March 2026.

Historical context of Go

Go was open‑sourced by Google in 2009. Its design has driven the evolution of modern cloud‑native platforms, influencing infrastructure providers such as AWS and Cloudflare and establishing Go as the default language for platform engineering.
