 ### Install support for PSCredential
 
-Azure Automation uses the [PSCredential](https://docs.microsoft.com/dotnet/api/system.management.automation.pscredential?view=pscore-6.2.0) class to represent a credential asset. Your scripts retrieve `PSCredential` objects using the `Get-AutomationPSCredential` cmdlet. For local development using the Azure Automation Authoring Toolkit, the cmdlet is part of assembly `AzureAutomationAuthoringToolkit`. For Azure working with the Automation context, the cmdlet is in `Orchestrator.AssetManagement.Cmdlets`.

-To be able to retrieve the Azure Automation credential asset `PSCredential` in your code, you can install the [Microsoft Azure Automation ISE add-on for the PowerShell ISE](https://github.com/azureautomation/azure-automation-ise-addon).

-```azurepowershell
-Install-Module AzureAutomationAuthoringToolkit -Scope CurrentUser -Force
