`Connect-ExchangeOnline` fails because `System.Windows.Forms` objects are used

[baldieavenger]

Hi,
When updating to the latest ExchangeOnlineManagement module, i'm unable to get the pop out to sign in. This works fine with 2.0.3 and in ISE / PowerShell.
Running 5.1 Powershell, 1.56.2 (system setup) Code.
Attached Diagnostic logs when both versions for comparison and a screenshot of the creds pop up Im expecting.
Thanks!
John

Hi, could you also open an issue with the module's repo too?

Hi Andrew,
Anything more you need from me to dig into this?
Thanks!

Hi @baldieavenger, thank you for your feedback.

I've tested it and it's working for me.

VS Code:

ISE:

Looks like its due to "System.Windows.Forms"

@baldieavenger your profile and script aside, is this issue alone resolved by the dev preview I had you try? That is, can you run Connect-ExchangeOnline in the integrated terminal?

@baldieavenger With the stable extension, I can reproduce the issue where the authentication prompt doesn't open at all from Connect-ExchangeOnline. With the dev build and Windows PowerShell, the authentication prompt does open for me in the integrated console. After authenticating, the module takes a looong time to finish, but eventually drops me back at a prompt, presumably having connected. With the dev build and PowerShell 7, instead of a GUI prompt, the module opens the browser for authentication; this still works correctly and then it sits loading for a while but eventually finishes.

So I believe my patch to OmniSharp has resolved the issue with Connect-ExchangeOnline in the integrated terminal.
