This is a trivial fix for an annoying extra post-installation step. The version of Azure Cmdlets installed to the ClientVM with the TP1 installer are not the “approved” version for Azure Stack. In order to experience any success with the additional Resource Providers you need to update the Cmdlets to version 1.2.1 Download Here.
Once you have obtained the updated MSI, mount the Installer VHD.
Once mounted navigate to the Dependencies folder.
Rename the MSI you downloaded before to azure-powershell.msi and copy over the existing file.
Unmount the image and copy the updated .vhdx to the install source you use.
