  XAML C# Object <MyObject SomeProperty='1'/> MyObject obj = new MyObject(); obj.SomeProperty = 1; <MyObject xmlns='clr-namespace:Samples' SomeProperty='1' /> using Samples; MyObject obj = new MyObject(); obj.SomeProperty = 1; <MyObject xmlns='clr- namespace:Samples;assembly=sampl es.dll' SomeProperty='1' /> csc /r:samples.dll test.cs using Samples; MyObject obj = new MyObject(); obj.SomeProperty = 1;

   WPF enhancementis the ability to develop an application using both markup and code- behind  XAML markup implements the appearance of an application  Managed programming languages (code- behind) implements behaviors  Data Binding  Events  Commands
• 8.
   Development andmaintenance costs are reduced because appearance-specific markup is not tightly coupled with behavior- specific code.  Development is more efficient because designers can implement an application's appearance simultaneously with developers who are implementing the application's behavior.  Multiple design tools can be used to implement and share XAML markup, to target the requirements of the application development contributors; Microsoft Expression Blend provides an experience that suits designers, while Visual Studio targets developers.  Globalization and localization forWPF applications is greatly simplified

  Elements that providetheir own content and behavior can also be containers of elements <Button Name="btnSubmit" Click="btnSubmit_Click" Width="200" Height="25">Hi </Button> <Button Name="btnSubmit" Click="btnSubmit_Click" Width="200" Height="200"> <Image Source="MVP.jpg"/> </Button> <Button Name="btnSubmit" Click="btnSubmit_Click" Width="200" Height="30"> <TextBox Width="80"></TextBox> </Button>
