 * **PowerShell**: support for Durable Functions is currently in public preview. Supported only for version 3.x of the Azure Functions runtime and PowerShell 7. Requires version 2.2.2 of the Durable Functions extension, or a later version.

+To access the latest features and updates, it is recommended that you use the latest versions of the Durable Functions extension and language-specific libraries. Learn more about [Durable Functions versions](durable-functions-versions.md).

 Durable Functions has a goal of supporting all [Azure Functions languages](../supported-languages.md). See the [Durable Functions issues list](https://github.com/Azure/azure-functions-durable-extension/issues) for the latest status of work to support additional languages.
 
 Like Azure Functions, there are templates to help you develop Durable Functions using [Visual Studio 2019](durable-functions-create-first-csharp.md), [Visual Studio Code](quickstart-js-vscode.md), and the [Azure portal](durable-functions-create-portal.md).
