Integrating Visual Studio Mobile Center and Trello using Azure Functions

Posted by Ed Snider on Nov 3, 2017 1:26:02 PM
My current project is an awesome project. We're using Xamarin.Forms to build beautiful native iOS and Android apps. And, if that isn't awesome enough, we've totally automated the build and distribution process of these apps using Visual Studio Mobile Center . I absolutely love Mobile Center and how simple it makes setting up CI/CD. You can literally setup a build job in less than 5 minutes with no build host machines or any of those types of complexities that normally come with setting up CI. As you can tell I'm pretty excited we're using Mobile Center to automate the app builds and releases for this project. But there was one thing I was still having to do manually - updating the Trello board after each build. Clearly this must be automated as well!

What is the xamarin platform?

We love tools that help our clients save time, but some of them are easily misunderstood. Here's the scoop on Xamarin.

Going Native: Using Android Views In Xamarin.Forms

Posted by Ed Buhain on May 30, 2017 11:05:39 AM


We previously walked through how to get started with a cross-platform Xamarin.Forms project, but what if we started with an Android app built in Android Studio? Here's a way to re-use a lot of our Android code and layouts with Xamarin.

Six Disastrous Mistakes for Cross-Platform Mobile Projects

Posted by Lee Richardson on May 11, 2017 11:21:20 AM

"I'm starting a cross-platform mobile project.  What problems should my team solve before we begin?"

What an enlightened question, I thought.

The individual standing next to me at a local developer conference had a software architecture background.  He clearly understood that laying a solid foundation at the outset of a project can either spell success, or result in project delays, massive technical debt, and quagmires for even rudimentary tasks.

As a consultant of nearly two decades I've seen all too well the results of poor project planning.  After 36 individual projects, eight of which were mobile, 4 of which were cross-platform mobile, I felt comfortable answering the gentleman's question with plenty of first-hand knowledge to back it up.

This post answers the question of what problems a mobile team should consider at project outset.  It's expressed in real world mistakes and the resulting consequences as I've witnessed them.

Xamarin.Forms: A Fire TV Quick Start

Posted by Ed Buhain on Apr 28, 2017 10:13:11 AM


How hard is it for a .NET developer to build a Fire TV app with C#? With the right tools, it's pretty easy; a Fire TV app is just an Android app optimized for viewing on a TV.

Since .NET's inception, my language of choice has been C#. For the C# developer, Xamarin is a useful tool for deployment to more than one platform, such as Windows, Android, iOS, or in our case, Fire TV. With Xamarin, we can build one set of back-end tests and code in C# and share the same code among all of those platforms.

Xamarin.Forms provides even more shared functionality: with Xamarin.Forms, we can even build our views using a set of controls common to all of our target platforms.

Kill AXML - Programmatic ListViews in Xamarin Android

Posted by Lee Richardson on Mar 16, 2017 2:26:38 PM

Displaying list data in Android using a custom layout is traditionally accomplished by inflating an AXML file for each row of data.  However, in my article introducing EasyLayout.Droid I made the case that AXML files slow development speed and decrease cross platform re-usability.

Introducing EasyLayout.Droid

Posted by Lee Richardson on Jan 11, 2017 3:33:06 PM

If you've done much Xamarin iOS work you've probably run into Frank Krueger's awesome framework, EasyLayout, that makes manually coded auto layouts considerably easier to read and maintain.

4 Xamarin Misconceptions Debunked (aka What Even Is Xamarin)

Posted by Lee Richardson on Jun 6, 2016 9:44:30 AM

This article explains what Xamarin is, the basics of how it works, and dispels four common misconceptions.

When Mary Jo Foley and Paul Thurott attempted and failed to describe Xamarin on Windows Weekly a couple of months ago, I grumbled about pundits not performing due research and moved on.  But when even Scott Hanselman (who I worship greatly admire) mischaracterized it on his most recent podcast, I realized there is sufficient confusion within our industry that additional clarification is needed.

Cross-Platform UI Testing with Specflow, Xamarin, and CodedUI: Part 3

Posted by Matt Wilhelm on May 19, 2016 11:20:10 AM

Welcome to Part 3 of my blog series on cross-platform UI testing.  For those who are just joining us, in Part 1 we discussed the high-level strategy for cross-platform UI testing using Xamarin.UITest and CodedUI, and introduced SpecFlow as the glue that holds everything together.  I also identified a couple of external resources that helped me put this together including Rob Gibbens' article about BDD Tests with Xamarin.UITest and SpecFlow; and finally we created initial cross-platform .  In Part 2 of this series, we took a big step towards implementing Xamarin.UITest patterns on windows by implementing Xamarin's IApp interface and defining a startup process so we could control the application's lifecycle.  In this post we will complete our journey by defining screens, creating CodedUI UIMaps, setting up our Xamarin project and ultimately creating our first tests using SpecFlow and Gherkin.

Cross-Platform UI Testing with Specflow, Xamarin, and CodedUI: Part 2

Posted by Matt Wilhelm on May 11, 2016 11:13:25 AM
Welcome to my blog series on cross-platform UI testing.  In Part 1 of this series, I discussed my strategy for corss-platform testing and identified a few key gotcha's to look out for along the way.  I also provided a link to the completed source code, should you like to follow along or find something specific.  Today we will go over implementing the initial project boiler plate.  Windows requires the most work, so lets get going!
