Hello,

I get below error. Is there someone with a solution or can point me to the right direction?

  1. Did you unblock the .dll files mentioned in the tutorial?
  2. Did you set this setting in your Azure app? "Advanced settings -> Allow public client flows -> Enable the following mobile and desktop flows -> Yes"

I had the same issue, suddenly comming up. It looks like, that unblocking all ps1 Files in all directories fixed it for me. So you might want to give it a try as well.

Out the gate, I couldn't get passed this same error after trying a bunch of things, but then it occurred to me that I was running it from PowerShell Core (v7.4.1) instead of plain old Windows PowerShell (5.1.17763.5576 to be exact). Running it from Windows PowerShell, suddenly it worked like a charm.

Thanks for all the options.

All files are unblock and still the same error under PSVersion 7.3.8.

Running under PSVersion 5.1.14393.6343 I get error below:

PS>TerminatingError(Get-ConnectionContext): "One or more errors occurred." PS>TerminatingError(): "Could not use the certificate for signing. See inner exception for details. Possible cause: this may be a known issue with apps build against .NET Desktop 4.6 or lower. Either target a higher version of .NET desktop - 4.6.1 and above, or use a different certificate type (non-CNG) or sign your own assertion as described at https://aka.ms/msal-net-signed-assertion. "

@BerryC Per my understanding, I'm using the latest version of .NET Framework. I'd recommend upgrading to the latest version and try that.
