## What it is
A C# library giving Blazor applications access to the browser's localStorage APIs, with automatic JSON serialization and deserialization of values. It supports both Blazor WebAssembly and Blazor Server and integrates via dependency injection.

## Use cases
- persist app state in the browser across page reloads in Blazor
- save user preferences to local storage in a Blazor app
- store and retrieve typed objects in localStorage from C#
- access browser localStorage from Blazor WebAssembly
- cache data client-side in a Blazor Server application

## When to choose
- you're building a Blazor WebAssembly or Blazor Server app and need typed localStorage access
- you want automatic JSON serialization/deserialization when saving objects
- you prefer DI-friendly, well-maintained wrappers over raw JS interop

## When to avoid
- you're not using Blazor (e.g. plain ASP.NET or JavaScript apps)
- you need large amounts of storage or IndexedDB capabilities
- you need server-side persistent storage rather than browser-local data

## Facets
- artifact type: library
- maturity: active
- function: serialization, json
- domain: web-development, frontend, developer-tools
- platform: browser, dotnet, cross-platform
- tags: blazor, localstorage, csharp, blazor-webassembly, blazor-server, browser-storage, nuget, web-server
