Specifies the internal execution behavior of a durable service contract implementation.
Assembly: System.WorkflowServices (in System.WorkflowServices.dll)
The following items are checked as part of the validation logic for durable services:
The ConcurrencyMode value must not be set to Multiple.
The InstanceContextMode value must be PerSession.
There must be one sessionful endpoint configured for the service.
If the contract disallows sessions, then CanCreateInstance must be set to true for all operations.
If SaveStateInOperationTransaction is set to true, then all operations on the service must either be marked with OperationBehaviorAttribute.TransactionScopeRequired set to true or marked with TransactionFlowOption.Mandatory. Additionally, ConcurrencyMode must be set to Single.
