You create a Microsoft Windows Installer file for a Windows Presentation Foundation (WPF) application that requires Microsoft .NET Framework 4.
You need to ensure that the installation starts only if .NET Framework 4 is already installed on the computer.
What should you do?

• A. Set the MinVersion property to .NET Framework 4.
• B. Set the Version property of Windows Installer to .NET Framework 4.
• C. Set the Version property of the Launch Condition to .NET Framework 4.
• D. Use a custom action.

You are developing a Windows Presentation Foundation (WPF) application.
This application will be deployed to 20 countries. However, it will only be localized to some of those countries' regional dialects.
The localization will be performed by using resource files. However, no culture will be specified in the project file with the UlCulture tags.
You must ensure that the application defaults to English for those regions that are not localized.
What should you do?

• A. Add the following code segment to the AssemblyInfo file. [assembly: NeutralResourcesLanguage("en-OS", DltimateResourceFallbackLocation.MainAssembly) ]
• B. Add the following code segment to the AssemblyInfo file. [assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallfcaclcLocation.Satellite) ]
• C. Add the following code segment to the Application constructor. Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
• D. Add the following code segment to the Application constructor. Thread.CurrentThread.CurrentUICulture= new CultureInfo("en-US");

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. The application contains the following code fragment.
<StackPanel>
<TextBlock Style="{StaticResource MyStyle)">Hello World</TextBlock>
<Button Style="{StaticResource MyStyle} ">Ok</Button></StackPanel>
You need to define a style that applies the following properties to the text in the StackPanel object:
- FontSize = 32
- FontWeight = Bold
Which code fragment should you use?

• A. <Style x:Key="MyStyle" TargetType-"{x:Type UserControl)">
  <Setter Property="Control.FontSize" Value="32" /> <Setter Property="Control.FontWeight" Value="Bold" /> </Style>
• B. <Style x:Key="MyStyle" TargetType-"{x:Type Control}">
  <Setter Property="TextElement.FontSize" Value="32" />
  <Setter Property-"TextElement.FontWeight" Value="Bold" />
  </Style>
• C. <Style x:Key="MyStyle" TargetType="{x:Type TextElement}">
  <Setter Property="Control.FontSize" Value="32" />
  <Setter Property="Control.FontWeight" Value="Bold" />
  </Style>
• D. <Style x:Key="MyStyle" TargetType="{ x : Type Framework-Element} ">
  <Setter Property="TextElement.FontSize" Value="32" />
  <Setter Property="TextElement.FontWeight" Value="Bold" />
  </Style>

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You create a custom control named Wheel.
You need to ensure that the Speed property of Wheel can be animated.
What should you do?

• A. Declare the Speed property as a dependency property.
• B. Declare an animation of the Speed property from within the code-behind file.
• C. Implement the System.Windows.Media.Animation.IAnimatable interface with the Wheel class.
• D. Inherit the DependencyObject class.

You are developing a Windows Presentation Foundation (WPF) application. The application contains a converter named DateOutputConverter that formats dates. The window is defined as follows. (Line numbers are included for reference only.)

The window must display the OrderDate value found in shippedOrder. The text box must display the OrderDate formatted by the DateOutputConverter.
You need to ensure that the OrderDate is displayed and formatted correctly.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. insert the following code at line 10.
  <textBox Text="{Binding OrderDate}"/>
• B. Insert the following code at line 07.
  <m:DateOutputConverter x:Key="internationalDateConverter"/>
• C. Insert the following code at line 10.
  <textBox Text="{Binding OrderDate,
  Converter={StaticResource internationalDateConverter}}"
  DataContext.="{StaticResource ResourceKey=shippedOrder}"/>
• D. Insert the following code at line 07.
  <m:DataOutputConverter x:Key"DataOutputConverter"/>
