## What it is
SmartFormat is a lightweight C# text templating library that serves as a drop-in replacement for string.Format. It supports named placeholders, lists, localization, pluralization, and extensible custom formatting at runtime.

## Use cases
- replace string.Format with named placeholders
- format strings with pluralization rules
- localize templated text messages
- format lists of data into strings
- build high-performance string composition in .NET
- extend string formatting with custom formatters

## When to choose
- you need more powerful string formatting than string.Format offers
- you want pluralization and localization in templates
- you need low-memory, high-performance runtime formatting
- you want a drop-in string.Format replacement in .NET

## When to avoid
- you need full HTML/view templating like Razor
- your project is not on .NET Framework 4.6.2+ or .NET 6/8
- you only need simple string interpolation already available in C#

## Facets
- artifact type: library
- maturity: stable
- function: templating, internationalization, serialization
- domain: developer-tools, web-development
- platform: dotnet, cross-platform
- tags: string-format, pluralization, drop-in-replacement, csharp, nuget, localization
