Acknowledgment
I'd like to first of all thank my girlfriend, Sandra Saenz Gonzalez, for her enormous support in taking on the project that this book was. I am greatly thankful for her constant understanding while having me closed up between four walls as I wrote and developed its contents. Thanks, Sandra, I love you.
Big thanks as well to my friend Jesus Salillas, who helped me with style reviews and guidance.
There are many good people out there who I have to thank, too. Thanks to Alfonso Rodriguez, who encouraged me to get into this "big .NET community world," and to Cristina Gonzalez, who has been my MVP Lead for—wow!—6 years already; easier said than done. Additionally, there is my good friend Paco Marin, who encouraged me strongly to write for him and his magazine, DotNetMania, now DNM, and during these years of collaboration, while writing for him, we have become good friends; thank you for all your support and care.
On the way, I found great friends out there, versed in the community, who allowed me to jump right at my passion. Thanks to the INETA guys, Damir Tomicic, Tomislav Bronzin, Sander Gerz, Andrej Radinjer, Andre Obelink, Christian Nagel, Dobrisa Adamec, and, of course, Miguel Lopez. Thank you for being there and doing what you do, greatly empowering the European developers' community. And for letting me take part in it and letting me "live it." One simple word—outstanding.
I'd like to give a big thank you to the staff of Packt Publishing for this opportunity, their support and patience on bringing this together, and for their understanding concerning my move to Switzerland, which had me a bit lost for a while (regarding the book). There you showcased that you are truly valuable, as a company and as people; special thanks to Rashmi Phadnis, Amey Sawant, and Dayan Hyames.
And finally I would like to thank Layla Driscoll, former Product Manager of the .NET CLR team, and Leon Welicki, Program Manager of the Workflow Foundation, both of whom I have had the honor of having as technical reviewers for this book. Thanks! It's awesome to count on you as reviewers.
I also have some friends who believed in me and encouraged me to write and said "I could do it"—thanks Braulio Diez, David Nudelman, Luis Franco, David Salgado, and Luis Fraile for your friendship, belief, and support.
I wouldn't have been able to write enclosed in the 15 square meters—my home for almost four months of my initial stay in Switzerland—if I couldn't take my stress out, which I did with my friends at Crossfit Zurich, so I want to give a big thank you to Ozi, all the coaches, and friends I have found at the "box" for being there!
And I will end by thanking those who started it all for me, that is, thanks to my father and mother for giving me birth and making me so curious; love you.
Thank you all!

Preface
With about 10 years since its first release, Microsoft's .NET Framework 4.5 is one of the most solid development technologies for creating casual, business, or enterprise applications. It has evolved into a very stable and solid framework for developing applications, with a solid core called the CLR (Common Language Runtime). Microsoft .NET Framework 4.5 includes massive changes and enables modern application and UI development.
Microsoft .NET Framework 4.5 Quickstart Cookbook aims to give you a runthrough of the most exciting features of the latest version. You will experience all the flavors of .NET 4.5 hands on. The "How-to" recipes mix the right ingredients for a final taste of the most appetizing features and characteristics. The book is written in a way that enables you to dip in and out of the chapters.
The book is full of practical code examples that are designed to clearly exemplify the different features and their applications in real-world development. All the chapters and recipes are progressive and based on the fresh features of .NET Framework 4.5.
The book is divided into functional examples that combine many techniques to showcase the usage of a concrete .NET 4.5 feature.
What this book covers
Chapter 1, Windows Store Apps, shows us the basics, 101, of creating Windows Store apps and some key aspects of it, such as adding a splash screen, tiles, understanding the Windows 8 lifecycle model, and using toasts.
Chapter 2, Exploring the Top New Features of the CLR, helps us explore some of the most exciting features of the CLR, such as portable class libraries, controlling timeout on regular expressions, overriding the default reflection behavior, and understanding how to use async and await.

Chapter 4, Understanding the New Features of Entity Framework 5.0, helps us explore Code First and Code First Migrations directly.
Chapter 5, Understanding the New Features of ASP.NET, helps us explore the new capabilities while creating an ASP.NET web forms application; it shows us how to use unobtrusive validation and explains what it is good for; and it focuses on the other improvements, such as smart tasks, WAI-ARIA support, and "extract to user control" between others.
Chapter 6, Implementing WPF New Features, covers the new way of handling errors in WPF asynchronously with INotifyDataErrorInfo, use the WeakEvent pattern with the WeakEventManager class, bind to static properties, Throttling data source update delays and LiveShapping, and repositioning elements in the view when its bound data gets updated.

Appendix A, Resources for Further Knowledge, provides key references to websites of interest regarding the areas covered in this book.
Appendix B, NET 4.5, Deployment Risks and Issues, will show us some issues that can happen when applying .NET 4.5 to an existing project and on its deployment, such as the limitation on platform, different behaviors of the .NET framework, and that some things that might work properly in our developer environment might not work as well when deployed.
What you need for this book
For working through this book, .NET 4.5 is needed together with Visual Studio 2012; we recommend either the professional or a superior version. Regarding the operating system, Windows 8 is needed for some aspects as well, so it is the recommended operating system.

Chapter 1. Windows Store Apps
In this chapter, we will cover:
Introduction
We are clearly speaking of a new, modern, and touch-friendly kind of application with the Windows Store apps style.
Windows Store app style application development, for the latest Windows 8 platform, is a very important part of this release of the .NET Framework 4.5.
We will explore Windows Runtime managed development in our development recipes. We also have the power of a very simple, well designed, and lightweight base class library API at our disposal (C# and VB) for developing Windows Store apps. This is called Windows Runtime, more commonly known as WinRT.
The following image clarifies the overall structure and components that we will have to use for developing Windows Store apps:
Portable libraries are there to help us port our existing code into multi-targeting scenarios such as Windows Store apps, Windows Phone, Silverlight, desktop, or X-box code with a strong focus on Model-View-ViewModel (MVVM). MVVM is an architectural design pattern designed for modern user interface (UI) development, very commonly used in XAML development. This will allow us to share the Model and ViewModel code with only the need for rewriting the UI and the application model, apart from the device integration.
Windows Store apps are designed for tablet devices and touch interaction, mainly for consumers. However, the good old desktop is still there and we can develop classic Windows applications, now called desktop apps, through the desktop mode.
Both of these execution and development modes coexist and are here for different scenarios. This chapter focuses on Windows Store apps development.
The Windows 8 app programming model basically:
WinRT provides projections that expose the API to the different development environments. With this we can use WinRT from the .NET Framework 4.5.
