XamlParseException after deleting settings (app.config)

Question

I get that exception, after deleting settings in my project. It is a default settings that using ProjectName.Properties namespace. Also i deleted app.config from project. Why i did that: i have been added serialize for reading my settings.xml instead of the old version.

I think these settings are defined somewhere, but dont know it.

This is text of exception, if it helps (translated in google translate):

Call the constructor for type" GnomeExtractor.MainWindow ", satisfying the specified binding constraints, led to an exception." Row number "6" and the position in the "9."

I deleted these files manually:

Settings.settings
Settings.Desighner.cs
app.config

My MainWindow.xaml code:

If i delete this, i got error in row 5 now, but next code is my styles and i can quietly delete this and it did not has no effect.

I have rolled back my project to working version, and got this error when i delete app.config

UPD: My MainWindow constructor's worked code

public MainWindow()
{
    // При первом запуске выставляем культуру установленную в компе, при последующих - предыдущую
    // First run changing localization same like in computer
    if (Settings.Default.ProgramLanguage == "")
    {
        string lang = "en-US";
        if (CultureInfo.InstalledUICulture.TwoLetterISOLanguageName == "ru")
            if (File.Exists("ru-RU\\GnomeExtractor.resources.dll")) lang = "ru-RU";

        CultureManager.UICulture = new CultureInfo(lang);
        Settings.Default.ProgramLanguage = lang;
    }
    else
        CultureManager.UICulture = new CultureInfo(Settings.Default.ProgramLanguage);

    CultureManager.UICultureChanged += new EventHandler(CultureManager_UICultureChanged);
    resourceManager = new ResourceManager("GnomeExtractor.Resources.Loc", Assembly.GetExecutingAssembly());

    //if (!File.Exists("loclib.dll")) MessageBox.Show("File loclib.dll not found, please reinstall the program");
    //if (!File.Exists("Gnomoria.exe")) MessageBox.Show("File Gnomoria.exe not found, please install the program in game folder");

    InitializeComponent();

    UpdateLanguageMenus();

    //Загружаем настроечки с прошлого запуска
    //Loading settings
    this.WindowState = Settings.Default.LastRunWindowState;
    this.Left = Settings.Default.LastRunLocation.X;
    this.Top = Settings.Default.LastRunLocation.Y;
    this.Width = Settings.Default.LastRunSize.Width;
    this.Height = Settings.Default.LastRunSize.Height;
    this.isCheatsOn = Settings.Default.LastRunCheatMode;
    this.isLabelsVertical = Settings.Default.LastRunIsLablesVertical;
    this.tabControl.SelectedIndex = Settings.Default.TabItemSelected;
    this.isAutoUpdateEnabled = Settings.Default.IsAutoUpdateEnabled;

    ControlStates();
}

Little explanation: Language={UICulture} + binding to a {Resx value} (XAML) and CultureManager class (C# code) is a lib for localization, using Resx files.
UpdateLanguageMenus() and ControlStates() just for a IsEnable controlling.

After deleting these files i replaced all of Settings.Default. to my new class of settings (using XML serialization) and just added this code

// Read settings from Xml file
settings.ReadXml();

/UPD

If you need more information, ask me about, please.

Woot, i found a problem, this is a good advice: https://stackoverflow.com/a/7857728/1808239

My settings.Fields.ProgramLanguage was a null, but not a ""
