Is there a way of setting culture for a whole application? All current threads and new threads?

We have the name of the culture stored in a database, and when our application starts, we do 

CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;

But, of course, this gets "lost" when we want to do something in a new thread. Is there a way of setting that CurrentCulture and CurrentUICulture for the whole application? So that new threads also gets that culture? Or is it some event fired whenever a new thread is created that I can hook up to?

This gets asked a lot. Basically, no there isn't, not for .NET 4.0. You have to do it manually at the start of each new thread (or ThreadPool function). You could perhaps store the culture name (or just the culture object) in a static field to save having to hit the DB, but that's about it.

Working solution to set CultureInfo for all threads and windows.

  1. Open App.xaml file and add a new "Startup" attribute to assign startup event handler for the app:
<Application ........
             Startup="Application_Startup"

  1. Open App.xaml.cs file and add this code to created startup handler (Application_Startup in this case). The class App will look like this:
    public partial class App : Application
    {
        private void Application_Startup(object sender, StartupEventArgs e)
        {
            CultureInfo cultureInfo = CultureInfo.GetCultureInfo("en-US");
            System.Globalization.CultureInfo.DefaultThreadCurrentCulture = cultureInfo;
            System.Globalization.CultureInfo.DefaultThreadCurrentUICulture = cultureInfo;
            Thread.CurrentThread.CurrentCulture = cultureInfo;
            Thread.CurrentThread.CurrentUICulture = cultureInfo;
        }
    }
