Try to compile following code
<Window x:Class="WPFLocalizationSample.MainWindow"

<StackPanel HorizontalAlignment="Left" Margin="20" VerticalAlignment="Top">
<TextBlock Text="{DynamicResource tbName}" Margin="2" />
<TextBox Width="200" Margin="2"/>
<Button Content="{DynamicResource btnAdd}" HorizontalAlignment="Left" Margin="2" />
</StackPanel>
<StackPanel HorizontalAlignment="Left" Margin="20,181,0,0" VerticalAlignment="Top" Orientation="Vertical" Width="305">

Here is MainWindow.Xaml.cs

Here is sample en-US.xaml (resource dictionary file)
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<sys:String x:Key="ResourceDictionaryName">en-US</sys:String>
<sys:String x:Key="tbName">Enter youe Name</sys:String>
<sys:String x:Key="btnAdd">Add</sys:String>
</ResourceDictionary>
Adding resource file in app.xaml
<Application x:Class="WPFLocalizationSample.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="en-US.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
if you compile this , you will see a form with two sample controls.
below translation panel added. you can type any text that you want to change
click on translate button changed text will updated in en-US file.
if you want to save different file also you can do.
Note: en-US.xaml file should be in release folder.
