Examples

//create the service placement policy
ServicePlacementPreferPrimaryDomainPolicyDescription placementPolicy = new ServicePlacementPreferPrimaryDomainPolicyDescription();
placementPolicy.DomainName = @"fd:\Datacenter1";

//add it to the Stateful Service Description
StatefulServiceDescription ssd = new StatefulServiceDescription();
ssd.PlacementPolicies.Add(placementPolicy);

Remarks

This constraint is usually used with fault domains in scenarios where the Service Fabric cluster is geographically distributed in order to indicate that a service’s primary replica should be located in a particular fault domain, which in geo-distributed scenarios usually aligns with regional or datacenter boundaries. Note that since this is an optimization it is possible that the Primary replica may not end up located in this domain due to failures, capacity limits, or other constraints.
