I just discovered that when running the optimizer within a Task/Tread/TPL Dataflow block with TaskExecutor set to ParallelTaskExecuter when instantiating GeneticAlgorithm, it blocks all other outside operations during the lifetime of the optimizer run. This does not happen when not setting the TaskExecutor option.

Most likely this is a bug? Is there a workaround? At the moment I can hence not run the objective function in parallel.

Can someone please help?
