A Roslyn-powered compile-time source generator for .NET that creates strongly-typed ID types from a simple attribute, eliminating boilerplate when wrapping primitives like Guid or int. It helps prevent primitive obsession by ensuring IDs of different entity types are not interchangeable.

Use cases

• generate strongly-typed IDs in C#
• avoid passing the wrong ID type to methods
• eliminate boilerplate for wrapping primitive IDs
• enforce type safety for domain entity identifiers
• generate code at compile time with Roslyn source generators

When to choose

• you use .NET 7+ and want type-safe entity IDs without hand-writing boilerplate
• you want to fix primitive obsession in a C# codebase with minimal ceremony

When to avoid

• you are not on .NET Core SDK 7.0 or greater
• you prefer runtime generics or value objects over compile-time generated types
