I have multiple Azure subscriptions linked to my account, so anytime I connect to Azure in PowerShell I have to make sure i am working in the right context. To simplify this I wrote a little helper function called Select-MyAzureRmSubscription.
After entering the -SubscriptionName parameter the script enumerates alll the subscriptions I have access to and generates a dynamic parameter option.
