Metalama 2024.0.2-preview released

[gfraiteur]

We have just released Metalama 2024.0.2-preview, which includes all changes from 2024.0.1-preview and 2023.4.6 plus the following:

New

• Metalama.Compiler: merge from Roslyn 4.8 preview.

• Support for C# 12: work in progress
  ✔️ Default lambda parameters
  ✔️ Inline arrays in run-time code
  ✔️ Allow nameof to always access instance members from a static context
  ✔️ Primary constructors
  ✔️ Type aliases.
  ❌ Inline arrays in compile-time code
  ❌ Collection expressions (aka collection literals) like [1,2,..array]
  ❌ AppendParameter advice (used in dependency injection scenarios) in primary constructors (planned for 2024.1).

• Code generation for multiple C# versions: Metalama will generate different C# code for projects built with different C# versions. Supported versions are 10, 11, and 12.

• Detection of the C# version required by T# templates: an error will now be reported if a project uses a template with features of a higher C# version than the one of the project.

Fixed

• In the documentation, the source code (before transformation) is now compiled with design-time artifacts generated by Metalama (i.e., generated partial classes and diagnostic suppressions) and, therefore, no longer contains irrelevant errors and warnings.

Breaking changes

• In the RefKind enum, In and RefReadOnly are no longer synonyms.
