I got an email stating that I was "associated with one or more Azure subscriptions that use version 1.x of the Azure Functions runtime." To my knowledge none of my Function Apps use version 1.x. How do I find out which function(s) I need to update, and why can't the mail be a little more specific? I mean it says I'm getting the email because I use version 1.x. That implies Microsoft knows of at least one function that uses 1.x, so which one?

@Saas SA ,
To find out which Function Apps are using Azure Functions version 1.x, you can use the following PowerShell script. This script generates a list of function apps in your subscription that currently target version 1.x:
$Subscription = '<YOUR SUBSCRIPTION ID>'
Set-AzContext -Subscription $Subscription | Out-Null
$FunctionApps = Get-AzFunctionApp
$AppInfo = @{}
foreach ($App in $FunctionApps)
{
if ($App.ApplicationSettings["FUNCTIONS_EXTENSION_VERSION"] -like '*1*')
{
$AppInfo.Add($App.Name, $App.ApplicationSettings["FUNCTIONS_EXTENSION_VERSION"])
}
}
$AppInfo
Replace <YOUR SUBSCRIPTION ID> with your actual subscription ID. This script will help you identify any Function Apps that are still using version 1.x, allowing you to take the necessary steps to update them.
The Microsoft script does not work.
PS C:\WINDOWS\system32> $Subscription = '<redacted>'
Set-AzContext -Subscription $Subscription | Out-Null
$FunctionApps = Get-AzFunctionApp
$AppInfo = @{}
foreach ($App in $FunctionApps)
{
if ($App.ApplicationSettings["FUNCTIONS_EXTENSION_VERSION"] -like '*1*')
{
$AppInfo.Add($App.Name, $App.ApplicationSettings["FUNCTIONS_EXTENSION_VERSION"])
}
}
$AppInfo

The method of manually checking each app in the portal is a non-starter. That'd be ok if I had one or two, but between my 3 subscriptions, there's nearly 100.
The script from demiliani worked after some tweaking to deal with multiple subscriptions, and I found that I updated an app and deployed it to my sandbox but then failed to deploy it to production.
