App.db.TableXXX.Where(...)...

But, how i can manage errors for all the application in a single event? I don't want use a try-catch on every single database request or update.

You can use Application.DispatcherUnhandledException Event to do that. All you have to do is add a method name App_DispatcherUnhandledException to App class (app.xaml.cs.)

void App_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
{
    // your code here
}
