Realm .NET SDK
The Realm .NET SDK enables client applications written in C# for the .NET, UWP, Xamarin, and Unity platforms to access data stored in local realms and interact with Atlas App Services services like Functions, MongoDB Data Access, and authentication.
Supported Platforms
Realm supports the following platforms for developing Realm apps for iOS and .NET devices:
Xamarin.iOS for iOS 9 or later, using native UI or Xamarin Forms
Note
Use Latest Xamarin.iOS Version
Starting with version 10.3.0 of the Realm .NET SDK, you must use Xamarin.iOS version 14.14.2.5 or later.
Xamarin.NET for API level 16 or later, using native UI or Xamarin Forms
Xamarin.Mac for macOS 10.11 or later, using nativeUI or Xamarin Forms
.NET Framework 4.6.1 or later for Windows 8.1 or later
Universal Windows Platform applications using .NET Standard 2.0 or later (Fall Creators Update)
.NET Core 2.0 or later on the following:
Ubuntu 16.04 or later
Debian 8 or later
RHEL 7.1 or later
macOS 10.11 or later
Windows 8.1 or later
You can use the following development environments to build Realm apps with the .NET SDK:
Visual Studio 2015 Update 2 or higher for Windows
Visual Studio for Mac 7.0 or higher
Unity 2020.3.12f1 (LTS)
Note
The Realm .NET SDK may be compatible with
other versions of Unity, but 2020.3.12f1 (LTS) is the version that the
Realm team uses for testing and development. We recommend using
this version to ensure your project works with Realm and that
the install steps match the Integrate Realm with Unity documentation steps since Unity's UI
often changes between versions.
Installation
To learn how to add the Realm .NET SDK library as a dependency to your application, see Install Realm for .NET.
To learn how to add the Realm .NET SDK library as a dependency to your Unity project, see the Integrate Realm with Unity documentation.
The Realm Data Model
You can store a wide variety of data within realms stored on your device, and if you enable Device Sync, updates to that data are available across multiple client devices. Data models are classes defined in your code and in realm schemas.
For information about the structure of data you can store in realms, see Realms, Objects, and Relationships.
Building C# classes to represent the data you store in realm ensures data consistency when serializing/deserializing and makes working with the data simpler.
Realm Database
Once you have defined the data model(s) for your application, you can write and read data to and from your realms.
To learn how to query for data in local realms, see Query Engine.
To learn about the results returned from realm queries, see Collections.
Mobile application development can be complicated by threading. To learn how to work with App Services across threads in your application, see Threading.
Atlas App Services
The .NET SDK also connects your Realm client application with your App's backend services, including Functions, Services, HTTPS Endpoints, Device Sync, and built-in third-party authentication.
To learn how to connect to an App Services app to call Functions, query data in an instance of Atlas, and synchronize data in realms, see Call a Function.
To learn how to handle schema updates in your client application, see Schema Versions & Migrations - .NET SDK.
