Flying with Xamarin and Telerik UI

Ask any developer about what code they are really proud to have written – the stories would be amazing. Maybe it is life-saving software in a healthcare system, or mission critical app in a global business or simply an open source library used freely by thousands of other developers. We software developers should take pride in our craftsmanship.

As for me, it was a WPF application – yup, I know, sounds boring. But I used to work at a private aviation company and we saw direct application of technology to aid the aviation industry.

Our application was used extensively by company dispatchers to do flight planning, tail routing and maintain operational safety. And boy – you do not want production bugs when you are flying business executives and Hollywood or sports celebrities. Glitches in our software could bring down planes and the company would probably not recover from the public relations disaster.

Sure we had some scary moments, but overall it was pride and craftsmanship in our applications that kept planes flying safely – day in and day out. I wish we had Xamarin for making cross-platform mobile apps back in those days.

This article combines two of my passions – a pure love for aviation and building connected mobile apps with Xamarin.

Jumpstart Your Xamarin App Development

So you want to build a mobile app? Your developer zen will quickly be threatened by the plethora of ways you can go about building a modern, cross-platform mobile app today. The below illustration shows an assortment of just a few of the technologies that you can use and the most common frameworks/platforms used for each.

This is what we have done to ourselves over the last 10 years. Choice is a good thing for developers, except that too much choice can become a little crippling.

On a positive note, the choice of technology stack becomes much easier once you decide to focus on what matters most – your skills and expertise. In today’s age, you really want to build truly cross-platform mobile apps from single codebase and preferably have the app be native to each platform. If your developer background is .NET, you’ll possibly lean towards using C# with Xamarin.

Xamarin lets you to build modern cross-platform mobile apps using your .NET skills. You write C#/XAML and your code gets cross-compiled down to native bits on each platform. This article walks you through some essential tooling that you should have in your arsenal for Xamarin development, as well as how to jumpstart your app with some polished UI.

Engineering the Future of .NET

While there is a huge army of engineers at Microsoft who work on .NET and C#, the following folks are arguably the most influential in bringing you the future of .NET and .NET Tooling.

  1. Scott Hunter
  2. Rich Lander
  3. Damian Edwards
  4. David Fowler
  5. Mads Kristensen
  6. Mads Torgersen

Let’s say you had an opportunity to have all of them sit down at a roundtable panel and fire away blunt honest questions. What would you ask?

This article dives into the mock questions I would ask, along with responses that are my personal best guess to the answers. Could my answers not reflect actual opinions shared by the team at Microsoft? Sure, but I’m hoping folks from the .NET team can jump in to correct me if I am way off base.

This is a rather interesting time for .NET – what’s being done shapes the future of .NET for the next decade. Let’s ask the honest questions and hopefully all of us will understand the new .NET ecosystem a little better.

The .NET CLI Decoded

You have done it hipsters. Thanks to you, we’re back in the 80’s and command line tooling is cool again – even for .NET development. Guess what else is hot? ASCII art! I’m contemplating adding some ASCII artwork on top of my C# code files, before heading out for the evening in my skinny jeans. That’s savage!


Jokes aside – the command line is really cool and powerful. And CLI tooling provides developers with lots of flexibility to aid in development and DevOps workflows, in addition to appealing to our inner geekiness. With the new .NET Core framework, the focus is squarely on CLI tooling to lower the barrier to entry and make .NET development accessible to all.

Whether you use Windows, OSX or Linux, the command line works the same way everywhere. Let us explore some of the new cross-platform .NET CLI tooling.

Biometric Authentication with Microsoft Passport

Information security is hard. Managing user authentication and authorization in apps/services usually gives developers an additional layer of headache on top of making applications actually work. Windows Hello and Microsoft Passport promise to be solid options for solving these issues.

Windows Hello offers easy biometric authentication that is integrated into Windows 10, taking away much of the pain around managing user credentials. But user authentication is just the first step of the problem. How do developers leverage biometrics to authorize users to apps/services?

That responsibility falls on Microsoft Passport – a seamless 2 Factor Authentication (2FA) system using device and user biometrics. Reusable user credentials can finally be replaced by biometrics and hardware-level security, thus enabling apps/services to offer robust built-in security.

This article unpacks Microsoft Passport and offers a walkthrough of how to utilize Microsoft Passport to power your apps. Seamless biometric security is wonderful, especially when you have the ability to leverage it in your apps. Let’s dive in.
