I think you misunderstood - I didn't want to imply that you shouldn't use tasks (or worker threads in general). For keeping the UI responsive/updating a progress bar while a lengthy operation is in progress it's the only option you have. Just when you do use tasks/threads you have to make sure you don't directly call control's methods but invoke that on the UI thread (which is likely the cause of the TargetInvocationException) - take a look the the link in my previous reply.
And I would recommend to separate the tasks from your custom control classes, but that's a design issue and not the immediate cause of your problem here.

Can you show the stack trace of the exception and the code where it occurs?
