// Apply the changes to the workflow instance
try
{
    instance.ApplyWorkflowChanges(changes);
}
catch (WorkflowValidationFailedException)
{
    // New state has already been added
    MessageBox.Show("On Hold state has already been added to this workflow.");
}

' Apply the changes to the workflow instance
Try
    instance.ApplyWorkflowChanges(changes)
Catch e As WorkflowValidationFailedException
    ' New state has already been added
    MessageBox.Show("On Hold state has already been added to this workflow.")
End Try

Remarks

If the workflow instance is not already suspended, the workflow runtime engine temporarily suspends the instance before applying the changes.
