Basically, you should either perform the IO in a separate thread using synchronous calls, or use asynchronous calls and handle events indicating progress etc. Using a separate thread is probably the simpler approach - and then use Control.BeginInvoke or Dispatcher.BeginInvoke to get the data back to the UI thread when it's finished loading.

Don't block the UI thread waiting for IO.
