StockSharp.Localization provides a flexible and extensible localization system for the entire StockSharp framework. The package contains the default English resources and utilities for switching languages at runtime. It works together with language specific packages located in Localization.Langs.

• JSON based resources – human readable strings.json holds the default English text for all UI elements and messages.
• Source generator – during build Localization.Generator converts the JSON file into strongly typed properties of the LocalizedStrings class.
• Runtime language switching – any number of language packs can be added and activated through LocalizedStrings.AddLanguage and LocalizedStrings.ActiveLanguage.
• Missing translation tracking – the Missing event notifies when a resource key or text does not have a translation.
• Automatic culture update – setting ActiveLanguage updates Thread.CurrentCulture and Thread.CurrentUICulture.

Add StockSharp.Localization as a NuGet package to your project. To include additional languages, reference the corresponding package such as StockSharp.Localization.ru or the meta package StockSharp.Localization.All.

The source generator is included automatically and requires no manual configuration.

Retrieve a localized string via the generated properties:

// get text for the current language
string text = LocalizedStrings.About;

// explicitly translate from one language to another
string russian = "About".Translate(from: LocalizedStrings.EnCode, to: LocalizedStrings.RuCode);

Switch the active language at runtime:

// change UI culture to Russian
LocalizedStrings.ActiveLanguage = LocalizedStrings.RuCode;

To add your own language:

1. Create a strings.json file with translations where keys match those in the base project.
2. Include the JSON in a new .csproj referencing common_lang.props (see examples in Localization.Langs).
3. Reference the resulting assembly in your application. LocalizedStrings will automatically pick it up when available.

Languages can also be loaded dynamically using AddLanguage(string langCode, Stream stream) at runtime.
