I am creating a form where I am giving a list box that is populated with images. There are many images as much as 20-200 and of high quality (resolution would be around 4000*5000). To optimize loading i am creating thumbnail of the images. But still it hangs the UI till all images completes loading. Therefore, I want to load this images Asynchronously so that user can do its further work, like selecting the file in list.
how can one interact UI thread in background worker??? how to do this??
