We’re excited to announce that Azure Functions now supports Go as a first-class language , available today in public preview on the Flex Consumption plan. Go developers can now build event-driven, serverless applications using idiomatic Go, the standard toolchain they already love, and the full breadth of Azure Functions triggers, bindings, and operational capabilities. TL;DR: Write Functions in Go using a new code-first programming model and SDK ( azure-functions-golang-worker ).
