## 2. Resource File Approach

### 2.1 Creating Resource Files

```
Project Structure:
├── Properties/
│   └── Resources.resx          (default/fallback)
├── Resources/
│   ├── Strings.resx            (default English)
│   ├── Strings.ko-KR.resx      (Korean)
│   ├── Strings.ja-JP.resx      (Japanese)
│   └── Strings.de-DE.resx      (German)
```

### 2.2 Resource File Content

**Strings.resx (English - default):**
```xml
<data name="AppTitle" xml:space="preserve">
    <value>My Application</value>
</data>
<data name="WelcomeMessage" xml:space="preserve">
    <value>Welcome, {0}!</value>
</data>
<data name="SaveButton" xml:space="preserve">
    <value>Save</value>
</data>
<data name="CancelButton" xml:space="preserve">
    <value>Cancel</value>
</data>
```

**Strings.ko-KR.resx (Korean):**
```xml
<data name="AppTitle" xml:space="preserve">
    <value>My Application (Korean translation)</value>
</data>
<data name="WelcomeMessage" xml:space="preserve">
    <value>Welcome, {0}! (Korean translation)</value>
</data>
<data name="SaveButton" xml:space="preserve">
    <value>Save (Korean translation)</value>
</data>
<data name="CancelButton" xml:space="preserve">
    <value>Cancel (Korean translation)</value>
</data>
```

### 2.3 Using Resources in XAML

```xml
<Window xmlns:p="clr-namespace:MyApp.Resources">
    <Window.Title>
        <Binding Source="{x:Static p:Strings.AppTitle}"/>
    </Window.Title>

    <StackPanel>
        <TextBlock Text="{x:Static p:Strings.WelcomeMessage}"/>
        <Button Content="{x:Static p:Strings.SaveButton}"/>
