Last week I wrote about Xamarin.Forms Embedding, a great new feature of Xamarin.Forms, that enables developers to convert a Xamarin.Forms ContentPage into an iOS UIViewController, Android Fragment, and a UWP Page. I walked through the current setup and a real world example of adding Xamarin.Forms details pages to my Xamarin Native application which previously only had native Storyboards and Android XML pages. When I …

You know I love Xamarin.Forms, but I also absolutely love Xamarin Native with iOS Storyboards, Android XML, and all of that UWP goodness. When you want to build an app that opens in sub-2 seconds, super optimized, and takes advantage of every custom control and animation out there (especially with material design) you have to go Xamarin Native. That is why the next evolution and favorite new feature, Xamarin.Forms …

I can’t help myself, I love Expression-Bodied Members from C# 6! Combined with other powerful C# features it took this code: public void OnPropertyChanged(string name) { var changed = PropertyChanged; if(changed == null) return; changed(this, new PropertyChangedEventArgs(name)); } to this: public void OnPropertyChanged(string name)=> PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name)); This is …

It allows you to set properties on elements or run specific code based on specific platforms. This is really nifty for tiny tweaks …

If you just updated to Xamarin.Forms 2.3.4 you may have noticed and be freaking out that you have tons of green squiggles that Device.OS and TargetPlatform are obsolete. This was all done in regards to the new changes for OnPlatform. We can see here that it says to use RuntimePlatform isntead, which is a string… but how do you use it??!?! If you hover over TargetPlatform, and enum, it doesn’t tell you what to replace …

Twitter recently launched Twitter Lite a stripped down “faster” and more “data friendly” version of their mobile app and refresh to their mobile website. It is more than just a new mobile website, it really is a Progressive Web App (PWA) that offers up notifications, camera integration, and some of the common features of twitter such as timelines, tweeting, and direct messages. It also benefits from being really …
