We are currently experiencing an issue with Service Fabric deployments after a recent change in response to another issue to add support for RegisterApplicationTypeTimeoutSec.
We are currently investigating and looking to provide a fix as soon as possible. As a potential workaround, it may be possible to get around the problem by using a custom DeployToServiceFabric.ps1 service fabric script.
We have raised a corresponding issue here which you can track the progress.
Sorry for any inconvenience this has caused!
