10. What’s Important?
 .NET is not going away.
 The full .NET client stack can be used to create Windows
applications that run in the Windows shell.
 A subset of .NET can be used to build Metro applications
using the WinRT framework.
 .NET applications on Metro are still compiled to MSIL.

11. Windows 8 Metro Applications
JavaScript
Windows
Runtime
C++ C#/VB

12. How does .NET Compare: C++
.NET C++
 .NET compiles to MSIL  C++ is compiled as native
code
 Will be just-in-time
compiled for the host  Will load and run faster
machine than C#
 No just-in-time compilation
 Can be built in AnyCPU
mode  Needs to be built for each
architecture
 Uses the WinRT framework
 Uses the WinRT framework
 Uses XAML for the UI
 Uses XAML for UI
 Subset of the .NET  Uses Standard Template
Framework Library
 Garbage collection  Automatic reference counting

13. How does .NET Compare: HTML5
.NET HTML 5
 .NET compiles to MSIL  HTML5 apps use the Internet
Explorer core hosted in a shell
 Will be just-in-time application provided by Metro
compiled for the host  Uses WinRT
machine  Most JavaScript libraries can
be reused:
 Uses the WinRT jQuery, KnockoutJS, etc.
framework  Metro JavaScript library
supports data binding and list
 Uses XAML for the UI controls
 Subset of the .NET  Metro applications have full
HTML 5 support and CSS 3
Framework
 HTML 5 applications are not
 Garbage collection limited to same server policy
