ArcGIS is a single thread application, the objects are not thread safe. This does not mean you can't use multiple threads just that you can't pass objects over the thread boundaries... instead of BackgroundWorker use system.threading.thread with ApartmentState of STA, create a new instance as @KirkKuykendall indicates then only pass non-Esri objects over the threads; there are some exceptions to this rule, but that's another topic in itself born of a thousand facepalm moments! | |

Furthermore, any new thread in which you are using ArcObjects should be an STA thread, which BackgroundWorker does not support. | |
