dotnet-localization
Comprehensive .NET internationalization and localization: .resx resource files and satellite assemblies, modern alternatives (JSON resources, source generators for AOT), IStringLocalizer patterns, date/number/currency formatting with CultureInfo, RTL layout support, pluralization engines, and per-framework localization integration for Blazor, MAUI, Uno Platform, and WPF.
Version assumptions: .NET 8.0+ baseline. IStringLocalizer stable since .NET Core 1.0; localization APIs stable since .NET 5. .NET 9+ features explicitly marked.
Scope boundary: This skill owns all cross-cutting localization concerns: resource formats, IStringLocalizer, formatting, RTL, pluralization. UI framework subsections provide architectural overview and cross-reference the framework-specific skills for deep implementation patterns.
Out of scope: Deep Blazor component patterns -- see [skill:dotnet-blazor-components]. Deep MAUI development patterns -- see [skill:dotnet-maui-development]. Uno Platform project structure and Extensions ecosystem -- see [skill:dotnet-uno-platform]. WPF Host builder and MVVM patterns -- see [skill:dotnet-wpf-modern]. Source generator authoring (Roslyn API) -- see [skill:dotnet-csharp-source-generators].
Cross-references: [skill:dotnet-blazor-components] for Blazor component lifecycle, [skill:dotnet-maui-development] for MAUI app structure, [skill:dotnet-uno-platform] for Uno Extensions and x:Uid, [skill:dotnet-wpf-modern] for WPF on modern .NET.
.resx Resource Files
Overview
Resource files (.resx) are the standard .NET localization format. They compile into satellite assemblies resolved by ResourceManager with automatic culture fallback.
