Storage

Uno.Extensions.Storage facilitate local data storage across multiple platforms, including WebAssembly, Android, iOS, macOS, Desktop and Windows. This extension is particularly useful for applications that require secure, persistent storage of user preferences, configuration settings, and sensitive information such as tokens and credentials.

Important

On Apple platforms (iOS, Mac Catalyst) the Uno storage extension, used by the authentication extension, uses the OS Key Chain service to store secrets. This requires your application to have the proper entitlements to work properly.

Installation

Storage is provided as an Uno Feature. To enable Storage support in your application, add Storage to the <UnoFeatures> property in the Class Library (.csproj) file.

<UnoFeatures>
    Material;

    MVUX;
</UnoFeatures>

Important

If your project doesn't have any of the Uno.Extension features set up yet, check out our Installing Extensions in an existing project docs to ensure you have all the necessary setup details.
