@jeffrey-ace is the management partner service GA, and is it expected that it ships with the stable AzureRM module?

[jeffrey-ACE-zz]

@cormacpayne Yes, management partner service is GA now, it is expected to ship with stable AzureRM module.

@jeffrey-ace Unfortunately, I don't think we can include this module in the AzureRM roll-up. We can make the change to stable, but this module will be an add-on install over AzureRM (or by itself)
