Embedding Xamarin.Forms into a Xamarin Native App #TheFuture

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 embedding, of Xamarin.Forms enables you to embed any Xamarin.Forms ContentPage int…

Getting started, step by step, in under 15 minutes!

Yesterday, we announced the Xamarin Live Player for both iOS and Android which includes the Live Player Extensions for both Visual Studio 2017 and Visual Studio for Mac enabling you to get started with mobile development with just a device! The Live Player apps let you debug your apps and make live edits and see them reflected live on your device. Your code runs inside of the Live Player app, so no emulator needed and everything happens over WiFi, so you don’t even need to plug anything in.

To get a good grasp of how the app works check out Miguel and me on stage at Build 2017 on the Future of App Development with Xamarin.

Getting started with the Live Players is super simple and we have AMAZING DOCUMENTATION that you should read to get started.

Now once you have things running be sure to read through the Limitations and the Troubleshooting guide if you run into any issues and join the discussion on the forums.

Important OnPlatform Changes in Xamarin.Forms

Last week I blogged about the important changes to Device.OS in the latest version of Xamarin.Forms. Well, I am back with some other changes from that same exact Pull Request that have to do with OnPlatform in code and XAML that use the new Device.RuntimePlatform. So, what is OnPlatform? It allows you to set properties on elements or run specific code based on specific platforms. This is really nifty for tiny tweaks to UI and can be done completely in the XAML, which is awesome. To make way for…

Colored Map Markers on Xamarin iOS and Android

I was getting ready for my next Tech Summit presentation and wanted to spice up my Maps for iOS and Android. I didn’t want to create any custom marker images or anything like that, but just wanted a little color flare on it. I knew there had to be an API out there to do it in each of the native frameworks and of course there was, so here is the quick and easy solution. (If you need this for Xamarin.Forms this would make a great Effect most likely). Android - Google Map Markers Surprisingly this…
