public abstract class WorkflowCommitWorkBatchService : WorkflowRuntimeService


When implemented in a derived class, initializes a new instance of the WorkflowCommitWorkBatchService class.


Gets the WorkflowRuntime for this service.(Inherited from WorkflowRuntimeService.)


Gets the state of the WorkflowRuntimeService.(Inherited from WorkflowRuntimeService.)


Called to commit the work batch.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


When overridden in a derived class, represents the method that will be called when the workflow runtime engine raises the WorkflowRuntime.Started event.(Inherited from WorkflowRuntimeService.)


When overridden in a derived class, represents the method that will be called when the workflow runtime engine raises the WorkflowRuntime.Stopped event.(Inherited from WorkflowRuntimeService.)

System_CAPS_protmethodRaiseServicesExceptionNotHandledEvent(Exception, Guid)

When overridden in a derived class, starts the service and changes the State to Starting.(Inherited from WorkflowRuntimeService.)


When overridden in a derived class, stops the service and changes the State to Stopping.(Inherited from WorkflowRuntimeService.)


Returns a string that represents the current object.(Inherited from Object.)

When a work batch is committed the runtime calls into the WorkflowCommitWorkBatchService and gives it a delegate to call to do the actual committing of the work batch. The runtime still has the primary responsibility of committing the work batch but allows the WorkflowCommitWorkBatchService to insert itself in the process for customization around the commit process.

This process allows custom error handling logic. If the WorkflowCommitWorkBatchService owns the transaction, which is the case when the Transaction.Current property returns null therefore necessitating the need to create a new ambient transaction, it is allowed to call the delegate more than once, creating a new transaction for each call. The most common case for this for example is to handle intermittent network problems or SQL cluster failovers. If the call to the WorkflowCommitWorkBatchService.CommitWorkBatchCallback throws an exception WorkflowCommitWorkBatchService can catch this exception, start a new transaction and call the delegate again. This gives a level of resilience to workflow instance execution that otherwise would cause workflows to terminate.

The following example demonstrates a class that inherits from WorkflowCommitWorkBatchService.

//Implementation of the abstract WorkflowCommitWorkBatchService class
class DefaultCommitWorkBatchService : WorkflowCommitWorkBatchService
    protected override void CommitWorkBatch(CommitWorkBatchCallback commitWorkBatchCallback)
        // Call base implementation
        catch (Exception e)
            // Report work batch commit failures
            Console.WriteLine("Work batch failed: " + e.Message.ToString());
