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#
