Have you heard about the FSharp TypeProviders? Type Providers allow you to access to a defined data scheme with static typing, which means to have intellisense for your data source. You can create your own or use one that the community has already created. Of course, there is already a JSON Type Provider, it will allow you to consume a JSON based REST api in a statically typed way. This increases the productivity a lot, you don’t have to spend time anymore trying to figure out what the name of a field is (see video below). If you combine this with the conciseness of FSharp and the productivity in the View side thanks to Xamarin.Forms, you end up with a triple win. This makes FSharp the best choice for mobile development. In this post I will try to show how to use the JSON Type Provider for building a Movies App using the TMDb API. There is an Apiary Type Provider too, but we won’t use it because the idea of this post is to figure out how to quickly build prototypes of your current APIs.

Steps to share a dictionary between the apple watch (or any app extension app ) and a device. 1) Create a group in the Apple Provisioning Portal. (eg. group.com.mycompany.myapp) 2) Add the group to both apps: the extension and the main app (there is no need to add the group to the actual watch app). 3) Activate the group in the Entitlements.plist for each project (main app and extension)

    Yesterday Xamarin just made my day. For the last few weeks I have been having fun learning Monogame and yesterday they announced that they will support Cocos2d by forking the existing Cocos2d-xna project.

Handling local notifications in Android is different as in iOS, so that code is non cross platform. On MvvmCross I like to handle that kind of scenarios in a custom Plugin, but this time, to keep the post very short I will handle it in the Activity that raised the notification.

Introduction: This time I want to show you how to combine three of my favourite technologies in a simple way: MvvmCross, Xamarin.iOS y Fsharp     Disclaimer: I'm not a FSharp expert. I just fell in love with the first line I wrote. There is so much power behind the scenes.   I want to keep the example as simple as possible so I based it on the easiest example of mvvmcross that you can find in CSharp (link).
