In this video, Gianluca Bertelli, an Escalation Engineer from Italy, will show you how to integrate Facebook within our Windows Store Applications – Using the class WebAuthenticationBroker to authenticate the users with any authentication provider that uses Oauth2 as protocol. You will see how to create an application that emulates a Single Sign On. The last topic covered is how to deal with the token that is returned by Facebook, how to store and reuse it later.

People are often asking me this recurrent question: how do I remote debug my website/app on a Windows Phone? Let me share the various ways to do it.

Since Visual Studio 2013 Update 2 and Windows Phone 8.1, the experience is getting much better. We will first see how to use this tool which enable html/css, JavaScript & even performance debugging!

I’ll share also at the end some great content demonstrating how to use WEINRE to debug layouts of Windows Phone HTML5 apps (PhoneGap/Cordova included).

Working with files is one of the most common tasks when developing any Windows Phone or Windows apps. In this mini-series of articles I'll show you available APIs in all Windows Phone and Windows versions, caveats when doing task such as checking if specific file exists, getting target file, reading writing data from/to files and also how to effectively extract data from ZIP files, and more.

In the first part of this series I'll discuss available File IO APIs in Windows Phone 8, 8.1 Silverlight, 8.1 XAML, Windows 8 and 8.1 platforms and benchmark all available methods for testing, if target file in Local Folder exists, or not. To my great surprise, the performance of methods in StorageFolder API is dramatically different across different platforms and it's not a good idea to use single approach everywhere.

There is always a clash between Google and Microsoft be it apps, APIs or operating system. When it comes to website analytics, Microsoft hasn’t got a solution and most websites rely on Google Analytics to keep a track on its usage. Google hasn’t released its official apps for Windows phone and likewise it doesn’t have an official SDK for analytics on windows phone but thanks to some excellent 3rd party SDKs its very simple to add it to your app. Here are four simple steps that would integrate Google analytics to your app.

I've been building some Windows 8 apps this week and stumbled across 3 ways in which you can create an image in Windows 8.1 HTML and JavaScript apps. One is to use a canvas element, construct the image as you want it and the use the BitMapEncoder to output a PNG. The second is to use the Windows 8 Webview Control and call the capturePreviewToBlobAsync() function. The third is to use the toBlob() function of the canvas element.

Admit it: If your room is cold and the thermostat is set to the higher temperature you want, you turn the thermostat up higher, don't you? We do that because we all have this mental model of thermostats that's organized around "achievement" -- we believe if we just ask our furnace to do a little more than we want, then the furnace will get us to what we want, faster. It's the same mental model your boss uses when giving you an impossible ("stretch") deadline: An impossible deadline will cause you to work harder and, perhaps, meet the real deadline that your boss is keeping from you.

I’m Christophe Nasarre and with my Italian collegue, GianLuca Bertelli, we are starting a short series about how to access Facebook services in Windows Store Apps. Today, I’m introducing the prerequisites of a Facebook connected App development. Gianluca will present the arcana of login and OAuth mechanism and the next episodes will cover different services such as photo access. But let’s start now with the prerequisites.

In my previous post, I talked about using the Camera with Forms- Kenmore dishwasher based applications. In this post I explain how to save and then use the photos you take.
