Visual Studio Code

Do you ever use some text editor such as Notepad++ to look into your code? If you do you could probably try something quite different, more powerful. Or, sometimes you want capability of Visual Studio IDE environment but need light weight version. Or, you want to use like Visual Studio IDE but on non Windows OS. You don’t want wizard but prefer command line tool. And you want Git support for your version control. All this could be yours using Microsoft tool called Visual Studio Code.

Visual Studio code is part of Visual Studio family and is light weight code editor that works on every platform: Windows, Mac OS X and Linux. When you install and start Visual Studio Code you get good starting point:


Visual Studio code combines two approaches: simplicity of code editor and with the best of what developers need in their edit-compile-debug loop:


What is really power of Visual Studio Code is great support for extensions that you can easily install to work with your language of choice:


Main features:

  • file and folder based source code editor
  • side by side editing (up to three editors open side by side)
  • great support for command line tools
  • navigation, keyboard support with customizable bindings, syntax highlighting, bracket matching, auto indentation, and snippets
  • built-in support for always-on IntelliSense code completion
  • built-in support for Node.js development with TypeScript and JavaScript
  • great tooling for web technologies such as HTML, CSS, Less, Sass and JSON
  • Git support
  • built-in debugger support
  • public extensibility model that lets developers build and use extensions
  • support for many languages through language extensions available on the VS Code Marketplace

You can find more information about Visual Studio Code on official page here.

If you prefer a code editor-centric development tool or are building cross-platform web and cloud applications Visual Studio Code is a tool that you must try.

Happy coding

New Microsoft documentation service

If you work with Microsoft technologies as developer you will for sure use one of the newest Microsoft documentation service which is running 100% on Azure. And please remember it because you’ll need it in the future:

Service started as preview in May 2016 but get more serious with the content few days ago when Visual Studio Update 3 and .NET Core 1.0 was publically released (27th June 2016). So why this new service?

As Microsoft would like to say, content matters. And indeed, if you look into the content I’m pretty sure that you would like it. MS created modern web experience for content, simple and effective. And what’s goal is that could be only one to rule them all:


So, the goal for Microsoft is to transfer all content from two popular services MSDN and TechNet into this new service. Of course, hard to believe that it would be done in near future, but for some time it will be for sure. New look and feel is created during the survey of hundreds of developers and IT Pros and getting feedback from UserVoice.

Some of the key features for the new services are:

  • Readability
  • Estimated Reading Time
  • Content and Site Navigation
  • Shortened Article Length
  • Responsive Design
  • Community Contributions
  • Feedback Mechanisms
  • Social Sharing
  • Friendly URLs
  • Website theming

You can find more about this key features here.


And if you look for the documentation for .NET Standard and .NET Core Guide, this is possible the best place.


You could also actively participate getting better experiences with your comments to this new service.

One downside of the site at the moment is that you can’t search the content. You can help if you provide your feedback here.

At the and, I would like to mention also one special place which is not new but interesting to remind you, Roslyn powered .NET framework reference source browser:

Happy coding

Microsoft Dev Center–Action needed for Age ratings

If you have apps in Microsoft Windows Store (Windows Phone or Windows Store app) you need to act in order that your app still be available in Microsoft Windows Store Apps.

Namely, Microsoft change Age rating policy for published apps that are not yet rated with new Dev Center Age rating questionnaire. But, just to be sure that you don’t miss this info, Microsoft already sent you email about this. So, if you don’t update new Age rating in Dev Center until September 30, 2016 your app will be unpublished.

What you need to do will cost you only few minutes of your time to finish everything what is needed. First, go to Dev Center, choose your published app, press Update button:


and you’ll see that Age ratings is incomplete:


Press Age ratings link and you’ll get start of the questionnaire:


So, if you didn’t rate your app till now choose first option and then pick up type of your app:


When you choose type of the app then you need to say Yes or No for few questions such as:

  • Does the app contain violent material?
  • Does the app contain sexual material or nudity?
  • Does the app contain any potentially offensive language?
  • Does the app share user-provided personal information with third parties?

These questions are really self-explanatory. After finishing this process you’ll find something like this for Age ratings:


At the end, Submit your app and you are done.

If you find out that you made mistake answering this questionnaire or you have change in your app you can always do the same process in order to change Age ratings for your app.

After some time, you’ll get email about IARC Rating Certificate providing a link to permanent record of this certificate.

NOTE: Downside of this action is that we will probably loose some apps from the store.

So, developers, please do this necessary update!

NTK conference 2016–presentation

I’m really proud that I have been part of the official Microsoft conference in Slovenia, NTK conference 2016, Portorož from 16th to 18th May 2016. It was one of the biggest and for sure one of the greatest technical conference in the region.

NTK Speaker

Some facts for the NTK conference for 2016:

  • 1700 participants
  • 150+ speakers
  • 10+ seminars
  • 21 year of tradition

My presentation took for the first day of conference with one session and it last for 60 minutes: Windows App Studio – Windows apps for 45 minutes.

So, what is Windows App Studio?

Windows App Studio is Microsoft’s Web development tool, which allows rapid and efficient development of applications for Windows without writing code.
No matter whether you are a developer or not, this tool will allow you the rapid development of Universal Windows Platform apps for Windows 10 (UWP) or Universal Windows apps for Windows/Windows Phone 8.1 based on predefined templates.
Although it is not functional as Microsoft Visual Studio, it gives a lot of possibilities and options for the development of very powerful and good designed WP8 applications.
Also you can benefit from Visual Studio and export your project in Visual Studio to fine tune your app.

In General, agenda for the session was as follows:
– Templates for creating new application
– Main application data: title, description, logo and language
– Application concept in Windows App Studio
– Defining data: data source, sections and using predefined data source
– Define custom data source using Collection data source
– Using static Resources
– Using App Studio Data Services
– Styling the app
– Generating application
– Export to Microsoft Visual Studio

Slides from the presentation you can find here.

Windows App Studio – new enhancements

Every few months we get new update in Windows App Studio. The newest one is ability  to use new app to install and share app created using Windows App Studio. Till now, it was very hard or better say complex to install app on device to test it (sideloading). Namely, you needed to deploy certificate using PowerShell scripts which was not the best and easiest way for sideloading.

Now, we have app you can install from the Windows Store, Windows App Studio Installer.  This app is UWP and you can use it on Windows Mobile 10 and Windows 10 operating system.

When you run it and have some apps that you installed with it, it looks like:


So, what is idea behind this app?

When you create app using Windows App Studio and create package for installment – appx package, you need to initiate download from Windows App Studio (click on download button in Windows App Studio – white box).


If you have installed Windows App Studio Installer, then it will start automatically and provide you install button for your app:


Windows App Studio Installer will download package and do install on device. Then you could even open newly installed app from Studio Installer.

So, what this tool is doing is:

  • When start download from Windows App Studio, it finds if your device is ready for sideloading or in developer mode in Windows 10. If not, it will open that settings page in order that you change that settings.
  • Automatically install necessary certificate if it is not installed on device.
  • Install app on device.

So, installing app from Windows App Studio is peace of cake as you can see.

Sharing app from Windows App Studio

When you create installable package from Windows App Studio, it is very easy to share your app with your friends. Just choose one of the provided options (email, twitter, facebook).


For instance, if you choose email, you need to provide email/emails to whom you need to provide your app. With that your app become public, whoever has link could install it.

Your friend will get mail with link to install app. Then it is the same process, user will download Windows App Studio Installer if it is not installed and then app will be installed.

Important Note: You can share app that is not published to Windows Store, then just created in Windows App Studio. When sharing app, you share just that specific version of your app. If you do update of the app, you again need to share new version!

With Windows App Studio, it is very easy to create Windows 10 UWP app and also easy to test and share app with your friends.

Happy coding

Cloud integration for UWP at Sinergija 15

I was one of the speaker for the one of the biggest conference in the region – Sinergija 15, held in Serbia, Belgrade from 21th till 23rd October 2015. This was great conference with long tradition and really great content. My presentation was at 22nd October with title:

Connected mobile experiences – Cloud integration for Universal Windows apps

Agenda for this presentation was:

  • Connected mobile experiences
  • Roaming data
    • Roaming settings
    • Roaming folder
    • Credential locker
  • Sharing state using One drive
  • Creating an Azure App Service – Mobile app
  • Offline sync
  • Push notification

Some of the tips for Roaming data:

  • Use roaming folder and roaming settings in the same way as local folder and settings.
  • HighPriority setting is available on Windows Desktop for quick sync but has no effect on Windows Mobile.
  • Good for app customization settings, most recent activity , partially completed work.
  • Synchronization stops if roaming data is larger then 100KB.
  • Bad for synchronizing large amount of data or instant syncing scenarios.
  • Last writer wins.
  • Data deleted from cloud if app not used for a period of time large than 30 days.
  • You can use capacity for roaming data in KB with RoamingStorageQuota.
  • Do not use Roaming data as a general purpose data syncing mechanism.

Azure App Service is one integrated offer:

  • Web apps
  • Mobile apps (know as Mobile Services in the past)
  • LOGIC apps
  • API apps

With Azure App Service you can:

  • Create web and mobile experiences that share data access and business logic.
  • Automate business processes with logic apps.
  • Build custom APIs or consume connectors from Marketplace
  • One common billing model for all of your App Services.
  • Use common Gateway to authenticate.

In presentation I also presented how to create Azure Mobile App and how to use offline data sync and how to work with push notification.


Happy coding

Picture Info update adds extensive list of changes

Social media coverage:

Picture Info for Windows Phone is kind of application that many users said that its functionality need to be part of the operating system as native feature. Many of us use Windows Phone device everyday as camera so we want to find out many information about picture. For that reason, Picture Info is perfect choice.


Picture info reads EXIF information that all images have incorporated such as width, height, file size, file name, date time picture taken, ISO Speed and many more and if image contains GPS coordinate, show location of the image on the map.

Main features:
