Lighting up Native Platform Features in Xamarin Forms – Part 2

In the previous post I implemented a custom attached property to be used in Xamarin Forms XAML when a built-in accessory view is desired on a table cell. In this follow-up we will continue and build out the iOS renderer that is responsible for actually enabling the feature in our running application. What about Android…

Lighting up Native Platform Features in Xamarin Forms – Part 1

In my last few posts I introduced a simple app that lets you browse the various built-in font variations supported by Xamarin Forms. If you recall, the application adopted a “stack navigation” design, which is quite common in mobile applications. However, there is one small flaw with our implementation so far – on the iOS…

Hey, Who Stole All My Memory?

Sometimes a little piece of seemingly innocuous code can cause a significant amount of trouble: [code language=”csharp”] public byte[] Serialize(object o) { using (var stream = new MemoryStream()) { MySerializer.Serialize(stream, o); return stream.ToArray(); } } [/code] Doesn’t look like much, but I’m sure we have all written something like this and paid it no mind.…

I mentioned in a previous post that F# can be used very well for enterprise applications. Here’s an in depth look at F# with Xamarin for…

Using F# for Enterprise Applications

Though I have posted a few times on some of the awesome things F# can do for your code, that doesn’t necessarily mean it’s always good choice for each of your applications. You may look at the code features and and some sample code and think This is great, but I can’t see this being…

API Convergence Gets Real in Windows 10

Last year, I wrote a universal app named Pic Me (later renamed to “Picture Me”) for Windows 8.1 and Windows Phone 8.1. The main reason I wrote it was that my daughter said “wouldn’t it be cool to have an app that shows you all the photos you’ve been tagged in on Facebook, and that…

Using AdaptiveTrigger to Build Adaptive UIs in Windows 10

Like a lot of developers, I’ve been watching the development of Windows 10 and digesting all the features Microsoft announced at BUILD. And I’m eager to build apps that target the Universal Windows Platform (UWP). UWP is a new model that allows you to write apps that run on a wide range of Windows devices,…

Supercharging Xamarin Forms with Custom Renderers, Part 5

Making Xamarin Forms Richer with Custom Visual Elements The BoxView class is handy for drawing rectangles in a Xamarin Forms UI. On Windows Phone, a BoxView renders a Rectangle element. On iOS and Android, it paints a rectangle onto a graphics context and a canvas, respectively. But what about other graphics primitives such as ellipses…
