Are there any known limitations with Windows Forms button scriptblocks? - azure

Question

I would like to build a Windows Forms application that uses the MicrosoftTeams module in the background and performs bulk actions.
To start with, a connection to Azure must always be established. For this I want to use the integrated Windows authentication.
For example, in the PowerShell Console I simply execute the following line to establish a connection:
Connect-MicrosoftTeams -AccountId ' user#contoso.com'
Now I wanted to execute this scriptsnipped when a button is clicked.
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.DImport-Module -Name MicrosoftTeams
$window = New-Object System.Windows.Forms.Form
$window.Width = 200
$window.Height = 200
$windowButton = New-Object System.Windows.Forms.Button
$windowButton.Location = New-Object System.Drawing.Size(10,10)
$windowButton.Size = New-Object System.Drawing.Size(100,50)
$windowButton.Text = "connect teams"
$windowButton.Add_Click({
write-host 'connecting'
Connect-MicrosoftTeams -AccountId 'user#contoso.com'
Write-Host 'connected'
})
$window.Controls.Add($windowButton)
[void]$window.ShowDialog()
However, the command cannot be executed correctly. PowerShell simply hangs on the command. There is no error message and no timeout.
Do you have any idea what the problem could be? Are these limitations of Windows Forms and if so, how can I work around them?
Edit:
I think my question was not formulated precisely enough. But it is very difficult for me to describe the problem. So I will share some additional codes/logs in hope that this will avoid misunderstanding.
If I change the authentication method from this:
Connect-MicrosoftTeams -AccountId 'user#contoso.com'
to this
Connect-MicrosoftTeams -Credential (Get-Credential)
the code works fine (also in the script block for the Windows form event button). Unfortunately, the user is then prompted to enter their username and password. I would like to avoid this at all costs.
So my guess is that the code inside the Windows Forms Button Event script block is not accessing the integrated Windows authentication.
To investigate the issue, I enabled the event logging feature for this cmdlet.
First, the log of the stuck cmdlet (within a Windows Forms Button Event script block).

So now my more specific question is: Is this phenomenon known to anyone or is this a known limitation of Windows Forms? Or is there a way to work around this problem?

Answer 1

You can create a function, of course, locate that at the top of your code, and call that in the click event as well.
Add-Type -AssemblyName System.Windows.Forms
# Add-Type -AssemblyName System.DImport-Module -Name MicrosoftTeams
function ConnectTo-MSTeams
{
[CmdletBinding(SupportsShouldProcess)]
Param()
Write-Host 'connecting'
Get-Date |
Out-Host
Write-Host 'connected'
}
$window = New-Object System.Windows.Forms.Form
$window.Width = 200
$window.Height = 200
$window.StartPosition = 'CenterScreen'
$windowButton = New-Object System.Windows.Forms.Button
$windowButton.Location = New-Object System.Drawing.Size(10,10)
$windowButton.Size = New-Object System.Drawing.Size(100,50)
$windowButton.Text = 'connect teams'
$windowButton.Add_Click({ConnectTo-MSTeams})
$window.Controls.Add($windowButton)
[void]$window.ShowDialog()

I don't have Teams installed, so, you need to test.
