The following example shows how to implement the OnResolveBookmark method.

protected override Bookmark OnResolveBookmark(object[] inputs, OperationContext operationContext, WorkflowHostingResponseContext responseContext, out object value)
{
    Bookmark bookmark = null;
    value = null;
    if (operationContext.IncomingMessageHeaders.Action.EndsWith("ResumeBookmark"))
    {

    else
    {
        throw new NotImplementedException(operationContext.IncomingMessageHeaders.Action);
    }
