Changelog

4.3.0

Minor Changes

• #100 41e920f Thanks @kieronlanning! - Use AddEmbeddedAttributeDefinition to inject Microsoft.CodeAnalysis.EmbeddedAttribute via Roslyn's official API, and apply [global::Microsoft.CodeAnalysis.Embedded] to all generated marker attribute types.

  This ensures generated marker types are invisible to IDE tooling and consumer code, eliminating spurious symbol conflicts. Requires Roslyn 4.14.0+ (ships with Visual Studio 2022 17.14+ and .NET 10 SDK).

All notable changes to this project will be documented in this file. See commit-and-tag-version for commit guidelines.

4.2.0 (2026-05-24)

⚠ BREAKING CHANGES

• consumers must build with VS 2022 17.14+ or .NET 10 SDK (10.0.200+). Runtime targets (.NET 4.8, .NET 8+) are unaffected.
