How to use Xamarin.Forms Messaging Center

The goal of MVVM is to abstract away your Views from your Business Logic. This ensures great code reuse, testability, and is pretty awesome.

These are built into Xamarin.Forms, which is awesome,…

Extending Xamarin.Forms Monkeys App with XAML and Images

Last week I posted an introduction to Xamarin.Forms article [http://blog.xamarin.com/meet-xamarin.forms-3-native-uis-1-shared-code-base/] on the Xamarin blog. I went over a simple master/detail flow with a list of monkeys that data bound to a ListView, and then navigate to a detail view displaying more information about the monkey when selected. It was a pretty simple implementation and I wanted to dive deeper into adding functionality. XAML Please! While the blog post got a great response, I…

Pull To Refresh for Xamarin.Forms iOS

Update Xamarin.Forms now includes Pull To Refesh out of the box. Please read my article on it. If you have read my blog then you know that I love pull to refresh functionality in all of my apps.

Xamarin.Forms shines in a lot of areas and the team has made it really easy to extend the built in controls or add brand new contr…

How To Get A Great App Icon: The Fiverr Experiment

As a developer I wouldn’t say I am the greatest graphic designer in the world. I mean I can stumble around Photoshop and make some sweet gradients and feather a few things, but that is about the extent of it. Over the last few years I have been pretty lucky to have a graphics design team at my back to make any image assets I needed and of course lay down the final App Icons that ship to the stores. Here are a few great app Icons that I didn’t have to create: Now that I create apps in my spare…

My StepCounter for Android goes Live & Open Source!

The past two weeks have been an absolute joy to take Michael James’ My StepCounter app for iOS and bring it to Android with C# and Xamarin.

Shared Code Projects in VS: Windows Phone, Windows Store, and Xamarin!

At Build, Microsoft announced Shared Code Projects to simplify how developers are sharing code between platforms. We have had official portable class library support for Xamarin apps since late last year and it has been wonderful, however once you mix WP8 into the mix the PCL profiles get a bit limited. Shared Code Projects attempt to fix this by allowing you to create a project that are a shell for code that can be added into any project. It is basically glorified file linking with a nice UI to…

Part 3: My StepCounter Android: Pretty UI!

I am no UI expert that is for sure, but I really like what Michael James did with the iOS version of My StepCounter. He made a nice background that changed colors from Red to Green, had a chromeless UI, and utilized very nice fonts.
