Live from Kiev: Building Mobile Cross-Platform Apps in C# with Xamarin


I love the Xamarin Platform. And not just because we just announced that Microsoft is acquiring Microsoft. I’ve been working with Xamarin technologies – and the Mono Framework – for years now. It’s one of the primary topics I’ve covered at major software conferences in the US, Canada and other countries. From VSLive, DevIntersection, DevTeach, CodePalousa to countless Meetups, user groups, and code camps, developers everywhere – especially .NET developers – want to learn how they can reuse their C# skills to build apps for iOS, Android and Windows while sharing 75% or more of their code.

Last October  I had the pleasure of being invited to speak at Dev Day Kiev in Ukraine, talking about Xamarin and also Azure App Services. I was fortunate enough that the sessions were filmed and recorded, and I’m here to tell you how to watch it.

Session Overview

Building native applications across multiple platforms is hard. iOS requires knowledge of Xcode, the iOS SDK and Objective-C or Swift. Android requires Eclipse Android Studio, the Android SDK and Java. The Windows 10 Universal Windows Platform requires Visual Studio, C# and the UWP/WinRT SDK. Are we really expected to learn all of this? You can take the HTML5 & Cordova route, but not all apps should be built using a hybrid approach. If you want to create a truly competitive app with a premium experience, you’ll need to go native. Fortunately, there is a way you can share a lot of your code across mobile platforms and do so using the C# language you already know and love.

Xamarin is a powerful toolset that allows developers to write native Android and iOS apps using C#, thanks to the Mono framework – an Open Source project that brings the C# language and .NET to other platforms. This session explores how you can build cross-platform applications for iOS, Android, and Windows 10 using C#. You’ll learn how to get started with a sample cross-platform solution, which tools you can use, how to design a proper user interface for each platform and how to structure your projects for maximum code reuse. We’ll also look at how you can share UI code with Xamarin.Forms. Native mobile development doesn’t have to be so hard. Come learn how your .NET skills can be transformed for true cross-platform development.

If you have questions on how to get started or want to discuss this topic, you can find me on Twitter at @ActiveNick. Be sure to let me know once you publish some C# apps – on any platform – I’d love to check them out and help you promote them.

Take a Video Tour of the Visual Studio Emulator for Android

I recently had the pleasure of sitting down with my good friend Robert Green to record another episode of Visual Studio Toolbox on Channel 9. This was my third appearance on the show, having covered my AzureChatr cross-platform chat app and developing Windows 10 apps with speech and Cortana in previous shows.

This time, Robert and I talked about the awesome Visual Studio Emulator for Android. That’s right, Microsoft actually makes an Android emulator. It’s full featured with support location services, accelerometer, camera, storage cards, network simulation and more. It’s super fast, thanks to hardware virtualization with Hyper-V and GPU support. And it’s free, totally free. You can even install it as a standalone app, without having to install Visual Studio, though you might as well get that too since Visual Studio Community Edition is completely free. Better yet, since the emulator plugs directly into ADB, you can use it with Android Studio, Xamarin Studio, Visual Studio, IntelliJ or Eclipse.

If you want to learn more and see the emulator in action, watch the following video below or on Channel 9.
