Questions tagged [realm-net]

This tag is for content related to the .NET/Xamarin version of Realm.io (the portable database engine).

Realm Xamarin is easy to work with, and makes your apps speedier. This should go without saying, but Realm Xamarin obviously allows you to write your app once in C♯ and target both iOS & Android (with more platforms to follow). Get started with an almost zero-configuration setup, and you're on your way. Objects in Realm work just like regular objects, so you already know how to use them. The real Realm magic comes when you need simple migrations or change notifications or built-in encryption.
