Question:

I am trying to fetch AAD app info using "Get-AzureADApplication" command. but getting the below error-

Get-AzureADApplication : You must call the Connect-AzureAD cmdlet before calling any other cmdlets. At C:\Users\v-pasahu\Desktop\Sample.ps1:18 char:11 + if($app = Get-AzureADApplication -Filter "DisplayName eq '$($AppName) ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Get-AzureADApplication], AadNee dAuthenticationException + FullyQualifiedErrorId : Microsoft.Open.Azure.AD.CommonLibrary.AadNeedAuthe nticationException,Microsoft.Open.AzureAD16.PowerShell.GetApplication

According to the error message, you need to run the command Connect-AzureAD first.

Besides, if you do not <a href="https://docs.microsoft.com/en-us/powershell/azure/active-directory/install-adv2?view=azureadps-2.0" rel="nofollow">install azure powershell module</a>, you should install it before using azure ad powershell.

Looking at the comments you have said you want to run this in the non interactive flow. To do this you must follow the instructions here to log in as a <a href="https://docs.microsoft.com/en-us/powershell/azure/active-directory/signing-in-service-principal?view=azureadps-2.0" rel="nofollow">service principal</a>.

Alternatively depending on what you are trying to do you may find it easier to Login using the AzureRm cmdlets.
