On 9th December, Microsoft announced that the go-live release of the Azure Functions 3.0 is now available. Among many new capabilities and functionality added to this release, one amazing addition is the support for the newly released .NET Core 3.1 — an LTS (long-term support) release — and Node 12.

With users having the advantage to build and deploy 3.0 functions in production, the Azure Functions 3.0 bring newer capabilities including the ability to target .NET Core 3.1 and Node 12, higher backward compatibility for existing apps running on older language versions, without any code changes.

While the runtime is now ready for production, and most of the tooling and performance optimizations are rolling out soon, there are still some tooling improvements to come before we announce Functions 3.0 as the default for new apps. We plan to announce Functions 3.0 as the default version for new apps in January 2020,” the official announcement mentions.

While users running on earlier versions of Azure Functions will continue to be supported, the company does not plan to deprecate 1.0 or 2.0 at present. “Customers running Azure Functions targeting 1.0 or 2.0 will also continue to receive security updates and patches moving forward—to both the Azure Functions runtime and the underlying .NET runtime—for apps running in Azure. Whenever there’s a major version deprecation, we plan to provide notice at least a year in advance for users to migrate their apps to a newer version, Microsoft mentions.
