AzureMLService Linked Service which uses a System Assigned Managed ID created with Set-AzSynapseLinkedService is not picking up typeProperties.authentication

[gitmadness]

Description

Failure I'm seeing is like https://github.com/Azure/azure-powershell/issues/17288 but for Set-AzSyanpseLinkedService.

I would create a Linked Service to an Azure ML Workspace using Synapse Workspace's System Assigned Managed ID using the following definition.

{
    "name": "test",
    "type": "Microsoft.Synapse/workspaces/linkedservices",
    "properties": {
        "type": "AzureMLService",
        "connectVia": {
            "referenceName": "AutoResolveIntegrationRuntime",
            "type": "IntegrationRuntimeReference"
        },
        "annotations": [],
        "typeProperties": {
            "subscriptionId": "xxxxxxx",
            "resourceGroupName": "myrg",
            "mlWorkspaceName": "myaml",
            "authentication": "MSI"
        }
    }
}

The cmdlet returns without errors.

However, I would get the error 9512 when I test the connection from the studio because "authentication":"MSI" property is missing from "typeProperties". I'm using 3.0.0 version of Az.Synapse.

Issue script & Debug output

Set-AzSynapseLinkedService -WorkspaceName 'myaml' -Name 'test' -DefinitionFile $tempFile -Verbose
