When attempting to make an Azure connection the following error occurs:
Connect-AzAccount : Method 'get_SerializationSettings' in type 'Microsoft.Azure.Management.Internal.Resources.ResourceManagementClient' from assembly 'Microsoft.Azure.PowerShell.Clients.Reso
urceManager, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.

This is discussed in https://github.com/Azure/azure-powershell/issues/21960
The solution is to close VSCode and install a previous version 2.12.2 using
Install-Module -Name Az.Accounts -RequiredVersion 2.12.2
Then remove the faulty version 2.15.1 in this case
Uninstall-Module -Name "Az.Accounts" -RequiredVersion 2.15.1
Connect-AzAccount then correctly prompts for credentials
While you are now able to us Connect-AzAccount in VSCode in may not be much use because it may be in compatible with other modules such as Az.DesktopVirtualistation.
You may be forced to run up to date compatible modules entirely from ISE.
