Agenda

Lets talk about existing technologies that can be used in Modern WPF Applications

Agenda• Putting WPF into perspective• What (was) new in .NET / WPF 4.5• Connecting to modern services such as OData, HTTP Services, SignalR• Entity Framework, Immutable Collections & Portable Class Libraries

• Enhancing touch experience using 3rd party controls• Integrating with Windows 8 Notifications• Taking advantage of the Windows 8 Touch Keyboard

WPF for WindowsDesktop Applications

Just the facts, what’s true today?

WPF is the best way to build Windows Desktop Applications when using .NET & Managed Languages (such as C# or VB.NET)

WPF in 2013• Modern & powerful platform for

building .NET Desktop Applications on Windows

• Fully supported & runs great on Windows 8• Easy to deploy within an organization

(ClickOnce, .NET 4.5 bootstrapper, etc)

.NET 4.5, including

Async

Entity Framework

Immutable Collections

(BCL)

Reactive Extensions

* Windows Runtime Note – MSDN DocumentationThe namespaces are exposed using API metadata format

(Windows.winmd) similar to that used by the .NET framework

Recap – .NET & WPF 4.5 Improvements.NET 4.5• Introduction of Async &

PLINQ• Introduction of Portable

Class Library• Zip Compression• Web Bootstrapper, no

more need for Client Profile Installer

WPF 4.5• Modify Collections on non-

UI Threads• Improved support for Weak

References to events• Async Data Validation• Binding to Static Properties

Connecting Modern WPF applications to Modern Services

OData• OData is a standardized protocol for creating and consuming data APIs

• OData builds on core protocols like HTTP and commonly accepted methodologies like REST. The result is a uniform way to expose full-featured data APIs

• Built on the manipulate data sets through CRUD operations (create, read, update, and delete)

HTTP Services• Stateless & scalable services over HTTP,

including RESTful Services• Communication over standard HTTP using

a handful of verbs (GET, POST, and so forth) plus a few simple concepts such as URIs and headers

• Connect any HTTP capable client including iPhone, Android or Windows Phone apps, Windows 8 Store Apps, WPF Desktop Applications, Etc

SignalR• SignalR is an ASP.NET library designed to

help developers simply the process of adding real-time functionality to their sites or apps

• SignalR enables real-time communication between server, apps and websites using WebSockets or fallback methods

• The source code for ASP.NET SignalR is available under an open source license

Demos of Modern Services & WPF

OData (created using ASP.NET WCF Data Services)

HTTP Services (created using ASP.NET Web API)

SignalR (created using ASP.NET & Open Source Nuget Packages)

.NET Framework

Portable Class Library (PCL)• A Class Library project that enables you to

write and build managed assemblies that work on more than one .NET Framework platform

• You can create classes that contain code you wish to share across many projects, such as shared business logic, and then reference those classes from different types of projects

• Works across Windows Phone, Windows Store, Desktop .NET Applications, Xbox 360 & Silverlight

Entity Framework• Entity Framework (EF) is an object-

relational mapper that enables .NET developers to work with relational data using domain-specific objects

• Entity Framework eliminates the need for most of the data-access code which developers usually need to write using T-SQL

• EF5 is currently available for production use (EF6 beta is also now available)

Immutable Collections• Immutable Types or your money back• The above is a joke, please don’t sue me

• Available Collection Types (in preview release)• ImmutableStack<T>• ImmutableQueue<T>• ImmutableList<T>• ImmutableHashSet<T>• ImmutableSortedSet<T>• ImmutableDictionary<K, V>• ImmutableSortedDictionary<K, V>

Learn More on the BCL Blog Post:http://aka.ms/DotNetImmutableCollections

Demos – Going beyond .NET 4.5 (via nuget)

Portable Class Library(Sharing Code, now with Async & HttpClient)

Data Access using Entity Framework(Using EF6 Beta, why not right, it’s a demo what can go wrong?)

WPF Desktop Applications &Windows 8

Windows 8 Toast Notifications• Windows 8 toast notifications are sent from

an app to the user that appear as pop-up notifications in the upper right corner of the screen

• A user can select the toast (touch or click) to launch the associated app

• Toast notifications can be sent by Windows Store and Windows Desktop applications or through a web service

Windows 8 Touch Keyboard (sample preview)• Windows 8 introduces a new touch

keyboard which is invoked by the operating system when touch input is detected in a text input field

• Windows Store apps automatically support bringing up a Touch Keyboard when a text field is active for input

• WPF Desktop applications must use automation & other logic to properly work with the touch keyboard on Windows 8

WPF Applications & Touch Input• Windows 8 is the best Windows operating

system for touch input• Windows Store & Windows Phone apps are

optimized for touch input and provide the best touch experience

• Desktop Applications such as WPF can be enhanced for better touch support through custom code or 3rd party controls

WPF UX Partners

• Dozens of WPF Controls to choose from• Full support for Visual Studio 2012

& .NET 4.5• Many controls enhanced for Touch Input

on Windows 8
