DurableOperationAttribute.CanCreateInstance Property

Gets or sets a value that indicates whether a new service instance can be created if an activation message is received on this operation. The dispatcher considers messages without an attached instance ID to be activation messages.

Namespace:  System.ServiceModel.Description
Assembly:  System.WorkflowServices (in System.WorkflowServices.dll)

public bool CanCreateInstance { get; set; }

Property Value

Type: System.Boolean
true if a new service instance can be created; otherwise, false.

If your contract disallows sessions, then CanCreateInstance must be set to true for all operations.

If the contract permits or allows sessions, then all operations for which CanCreateInstance is set to true must be request/response operations: that is, IsOneWay cannot be set to true.
