.SYNOPSIS Get client application from local session cache. .DESCRIPTION This cmdlet will return a client application object from the local session cache. If it does not yet exist, a new client application will be created and added to the cache. .EXAMPLE PS C:\>Get-MsalClientApplication -ClientId '00000000-0000-0000-0000-000000000000' Get public client application using default settings. .EXAMPLE PS C:\>$ConfidentialClientOptions = New-Object Microsoft.Identity.Client.ConfidentialClientApplicationOptions -Properties @{ ClientId = '00000000-0000-0000-0000-000000000000' } PS C:\>$ConfidentialClientOptions | Get-MsalClientApplication -ClientSecret (ConvertTo-SecureString 'SuperSecretString' -AsPlainText -Force) -TenantId '00000000-0000-0000-0000-000000000000' Pipe in confidential client options object to get a confidential client application using a client secret and target a specific tenant. .EXAMPLE PS C:\>$ClientCertificate = Get-Item Cert:\CurrentUser\My\0000000000000000000000000000000000000000 PS C:\>$ConfidentialClientOptions = New-Object Microsoft.Identity.Client.ConfidentialClientApplicationOptions -Properties @{ ClientId = '00000000-0000-0000-0000-000000000000'; TenantId = '00000000-0000-0000-0000-000000000000' } PS C:\>$ConfidentialClientOptions | Get-MsalClientApplication -ClientCertificate $ClientCertificate Pipe in confidential client options object to get a confidential client application using a client certificate and target a specific tenant. #> function Get-MsalClientApplication { [CmdletBinding(DefaultParameterSetName='PublicClient')] [OutputType([Microsoft.Identity.Client.PublicClientApplication],[Microsoft.Identity.Client.ConfidentialClientApplication])] param ( # Identifier of the client requesting the token.
