Error Resolved: IOException - Cannot locate resource

Introduction 

Recently I worked on a WPF application which supports localization using LocBAML tool. I created a sample application, having a very simple UI, consist of a button inside a window. Here I am assuming that most of you are aware on how to generate satellite assemblies. So, quickly coming to the point, when I build my application, build was successful. But when I launched, my application crashed with reason stated as IOException. Alas !!! 

After spending almost an hour, I came to know that it was due to Culture settings. Let's have a look at my code first:

<o:p>

Using the code 

My App.xaml.cs looks like this:  

public partial class App : Application
    {
        public App()
        {
            CultureInfo fr = new CultureInfo("fr-FR");
            Thread.CurrentThread.CurrentCulture = fr;
            Thread.CurrentThread.CurrentUICulture = fr;           
        }
    }  

Apart from this above code, I also updated my project file (.csproj) for development language so that my satellite assembly contains the neutral language resources. Following line was added in the project file:  

<UICulture>en-US</UICulture> 

[assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.Satellite)]
