How to get Azure storage account associated with Azure function app via PowerShell

As you probably know Azure function app is provisioned with Storage account behind it which is used for internal needs of function app (e.g. storing compiled dlls of Azure functions in blob storage of this storage account or storing App insights logs in tables). If we need to get instance of this storage account associated with Azure function app we may use the following PowerShell:

$app = Get-AzWebApp -Name "MyFunctionApp" -ResourceGroupName "MyResourceGroup"
$kv = $app.SiteConfig.AppSettings | Where-Object { $_.Name -eq "AzureWebJobsDashboard" }
$found = $kv.Value -match ".*;AccountName=(.+?);"
$storageAccountName = $matches[1]
$storageAccount = Get-AzStorageAccount -StorageAccountName $storageAccountName -ResourceGroupName "MyResourceGroup"

In above code we first get instance of function app using Get-AzWebApp cmdlet and find AzureWebJobsDashboard application setting which contains connection string of associated storage account. After that we retrieve storage account name from connection string using regex and finally call Get-AzStorageAccount to get actual storage account instance. Hope it will help someone.
