Project the Windows Phone 8.1 screen to your PC using USB

Windows Phone 8 devices that have been updated to Windows Phone 8.1 using the developer preview can now project their screens to a computer connected via USB.

The first step is to download and install this desktop driver and client app.

it’s enough to just connect the phone to the PC using USB and start the “Project My Screen App” on the PC.

The phone will ask for permission to activate screen projection.

Some nice facts on how Windows Phone 8.1 handles files.

One of the new features of Windows Phone 8.1 is sharing, very much like the share charm in Windows 8, and the new file picker.

The share contract allows apps to share freely with no limitations on the content type. Text, links, HTML, images, files, or even custom file types.

The new file picker goes a step further. Apps can use it to open and save files in the phone’s storage, SD card, or OneDrive.

If an app wants to load pictures, the user will be presented with the photos app. But if you need to get to a photo in another location (like your SD card or OneDrive), you can select ‘Choose location’ on the Photos app’s app bar and access the file picker.

A very nice twist: custom apps can be file providers too and allow their files/data to be accessed by the user using other apps.

This works in both Windows Runtime apps (i.e. Universal Apps) and Silverlight 8.1 apps.

To learn more on the topic, have a look at The Build 2014 session: “Contracts and Pickers: Building Apps that Work Together on Windows”

Also, Internet Explorer 11 now allows to download/save files when tapping on a link on a webpage.

You can then immediately access the downloaded file using IE:

…or you can connect your phone to your computer, access it’s folders and find a new subfolder “Downloads” containing the downloaded files.

Also, the newly available “Field Medic” App, a premier diagnostic application for Windows Phone that allows easy collection of device information and ETW logs right from your device, adds its own, user accessible folder where collected logs are stored.

Very nice, indeed!

Hands-On Lab: Building your first App for Windows 8.1 and publishing it to the Windows Store.

I recently created this hands-on lab and ran it in  an on-site event here at Microsoft Switzerland. People gave me very good feedback so I decided to publish it in full.

The lab contains everything you need to complete the exercise, including a detailed, 50 page step-by-step manual as Word- or PDF document. Every step is well explained so you don’t need prior Windows App development experience.

In it, you will be creating a YouTube video player app from scratch (File, new Project) for a specific YouTube channel and publish it to the Microsoft store. The final app will look something like the following, but you can tailor it to your YouTube channel of choice.

The lab also makes use of some of the new Windows 8.1 controls like the Hub and the Microsoft Player Framework to play back streaming video.

Windows 8 features like the App bar, asynchronous programming and sharing videos through the Share Charm are all covered.

Also, all the sometimes confusing publishing steps are explained in detail, including how to optimally create properly sized screen-shots using the simulator in Visual Studio 2013…

…and test the app using the “Windows App Certification Kit”, so publishing is as smooth as possible.

Prerequisites

All you need to complete the lab is a computer running Windows 8.1 and a version of Visual Studio 2013, that can create XAML/C# based Windows store apps. The free “Visual Studio Express 2013 for Windows” edition will do just fine.

To publish the lab, you will need an active Windows Store account, details how to sign up can be found here and here. Pricing per year is CHF 17 for individuals and CHF 90 for companies
