Local deployment — change the default location
This can be done using the DevClusterSetup powershell script, located (at least for me) in C:/Program Files/Microsoft SDKs/Service Fabric/ClusterSetup/
You want to run the script as follows:.\DevClusterSetup.ps1 -PathToClusterDataRoot <desired_app_and_data_location>
Thanks to Sean McKenna How can I specify where my local developer's service fabric cluster is created?
