 ## DESCRIPTION
 The **Get-AzDeploymentWhatIfResult** cmdlet gets the ARM template What-If result for a template deployment at the current subscription scope. It returns a list of changes indicating what resources will be updated if the deployment is applied without making any changes to real resources. To specify the format for the returning result, use the *ResultFormat* parameter.
