You can try this:
void runBootStrapProcess() {
MetadataReader mr = new MetadataReader();
if (currentVersionNo.Equals(remoteVersionNo)) {
Application.Current.Shutdown();
} else {
System.Windows.Application.Current.Dispatcher.BeginInvoke(
new Action(
() => {
MainWindow mw = new MainWindow();
mw.Show();
}));
}
_loadingProgressBar.ShouldCloseNow = true;
}
You basically from the thread when you want to show the window send it to the main application thread. This thus stops the application from closing down when the thread exits since the MainWindow
is Shown from the main thread.
