Universal Windows Platform Application on Raspberry Pi

Universal Windows Platform (UWP) provides a common app platform on every device that runs Windows 10. The core APIs in UWP are the same on all Windows devices – including Desktop PC, Mobile Phone, XBox, Hololens, IOT devices and others.  You can target specific device capabilities of a device family with extension SDKs, but you don’t have to do that if you are only using core APIs. Those core APIs include a very impressive set of UI capabilities. What that means is that you can create a UWP application using C# and XAML which will run on an ARM based processor on Raspberry Pi – because Windows 10 IOT Core runs on that. Universal Windows Platform (UWP) has come a long way. I decided to […]

PackRaft with Xamarin and Microsoft Azure

PackRaft is a cross-platform mobile application built with Xamarin. It integrates with Microsoft Azure services, such as Azure Table Storage and Azure App Service. It is created with Xamarin.Forms for iOS and Android (Windows version will be coming soon).     The purpose of creating this sample application was to expand expertise in cross-platform mobile development with Windows Azure integration, specifically with Xamarin.Forms and Azure App Service. With Xamarin.Forms, it is possible to achieve close to 100% code reuse across these platforms for certain type of apps. Azure App Service provide a set of rich cloud backend services for your mobile applications. PackRaft allows the user to setup a fleet of vehicles of various seating capacities. Groups of riders are assigned to these rides according to the […]

Creating Android Apps using C# and Xamarin

You can create native Android and iOS applications using C#, with Xamarin. I explored the capabilities of Xamarin tools and the development experience with Xamarin to create an Android version of CensusMapper. CensusMapper displays U.S. Census data on a Map. I created the original application for Windows 8 (WinRT) using C#. I have since converted it to an MVVM (C#) application, HTML/Javascript (WinJS) version and more recently to a Universal Windows App running on Windows Phone 8.1 and Windows 8.1. In that tradition, now it is faithfully ported to run on Android devices, using C# and Xamarin. CensusMapper is available on Google Play Store. CensusMapper.Android shows population of each U.S. State. User can tap on a location on the map to […]

Universal Apps

The story of Windows Universal Apps is the result of advancements in three areas: The platform convergence between Windows 8.1 and Windows Phone 8.1 The (ongoing) unification of Windows and Windows Phone stores. Shared Projects and other enhancements in Visual Studio 2013 Update 2 to support cross-platform development. I have written about my experience in converting an existing Windows 8 app, CensusMapper, to a Universal App on the AIS Blog. Read the article here. I have also created another Universal App, LRMS, using Windows App Studio. This app is available in both Windows and Windows Phone Stores. I gave a presentation at the Raleigh Code Camp this past weekend : Creating Universal Apps for Windows Phone 8.1 and Windows 8.1. Thanks […]

Announcing CodeDemo

It is a challenge to use code snippets in presentations, demos and live coding sessions. I have struggled with this and seen many speakers jumping through hoops to assimilate code snippets in their demos. I had to create something to ease this pain. Today, I am announcing the general availability of CodeDemo. A tool for instructors, presenters and speakers who create instructional demos, record screen-casts or do live presentations. CodeDemo pastes code snippets into your favorite IDE without getting in your way. I decided not to open-source CodeDemo to challenge myself to an exercise in commercialization. I decided to learn about entrepreneurship, marketing, sales, licensing and other aspects of software commercialization. It has been an MBA’s worth of education so […]
