Hi,

We are planning to build out Azure Functions but there is dependency on some .NET Framework v4.7 code that we need to re-use. What is the support for Azure Functions v1 running in production (in terms of issues, incidents if any)

    Hi @Suganya Karunanidhi
    Azure Functions currently supports three versions of the runtime host: 1.x, 2.x, and 3.x. All three versions are supported for production scenarios.

    Version 1.x is in maintenance mode and only supports development in the Azure portal.
    Run on a specific version
    By default, function apps created in the Azure portal and by the Azure CLI are set to version 3.x. You can modify this version as needed. You can only change the runtime version to 1.x after you create your function app but before you add any functions. Moving between 2.x and 3.x is allowed even with apps that have functions, but it is still recommended to test in a new app first.54612-capture.jpg
