Connect-MSGraph does not accept credential object in PowerShell Core

[corbob]

Is there a technical reason for only accepting a PSCredential object within Windows PowerShell? As pwsh is able to use PSCredential objects, it would stand to reason this should be used there too...

@corbob Thanks for raising this issue. You are correct that PSCredential objects can be used with PowerShell Core. However, the .NET Core version of ADAL (the authentication library used in the module) does not support passing in a username and password. This is why the PSCredential method of logging in wasn't exposed in the PowerShell Core version of the module.

See ADAL issue 482: AzureAD/azure-activedirectory-library-for-dotnet#482
