I want to use a PowerShell script to imitate an IoT device that sends messages to and event hub in Azure. I’ve created the script below, but when I run it, it gives the error Send-AzEventHub’ is not recognized as the name of a cmdlet, function, script file, or operable program.
My PowerShell ISE is version 5 and PowerShell 7 is only a command line utility. And I can’t get PowerShell extension working in Visual Code.
So I tried the Cloud Shell in Azure portal, but I get the same message.
Anyone an idea how I can get a script going the simulated a IoT stream?
