Published Nov 08 2021 08:00 AM 67.1K Views

The Azure Functions team is excited to announce the general availability (GA) of Azure Functions 4.0. This is the latest release of Azure Functions that supports: .NET 6, Node.js 14, Python 3.7-3.9, Java 8 & 11, PowerShell 7.0, and other languages and runtimes using custom handlers.


General availability of .NET 6 support


Today is the GA release of .NET 6. The .NET 6 support in Azure Functions 4.0 is also generally available today.


Azure Functions joins Azure Web Apps and Azure Static Web Apps who also announced .NET 6 support today.


For .NET, Azure Functions supports both in-process and isolated (out-of-process) execution models. Choose in-process if you are upgrading from .NET Core 3.1 Azure Functions or if you are looking for features, such as Durable Functions, that are currently only available to in-process apps. Isolated function apps provide more control of the function worker process and greater compatibility with libraries. For more information and to learn more about the .NET roadmap for Azure Functions, read our blog post from earlier this year.


To learn more, join our session at .NET Conf—"Serverless .NET 6 with Azure Functions"—streaming live on November 10 at 20:30 UTC (12:30 PST) and available on-demand following the conference!
