Nouveautés de ReSharper 2024.3

C# 13 updates

With its latest release, ReSharper introduces support for the latest features that come with C# 13, namely:

• Nouvelles collections params : le mot-clé params a été étendu pour fonctionner avec différents types de collections, ce qui permet d'améliorer l'efficacité des signatures de méthodes sans allocations supplémentaires.
• Partial properties: Support has been added for partial properties, enabling you to spread property accessor implementations across multiple files, increasing flexibility and organization in your codebase.
• Nouveau type lock : le nouveau type System.Threading.Lock a été introduit pour une synchronisation des threads plus efficace. Il améliore les performances par rapport à l'instruction lock traditionnelle.
• Priorité de résolution de surcharge : un nouvel attribut vous offre un meilleur contrôle de la résolution de surcharge des méthodes et permet aux développeurs de prioriser quelle surcharge est appelée dans des scénarios complexes.
• Mot-clé field : la prise en charge du mot-clé field (fonctionnalité preview) a été ajoutée. Cela donne un accès direct au champ de stockage des propriétés automatiques et simplifie la logique des propriétés.

In ReSharper 2024.3, code cleanup has been re-engineered for more robust performance. It now leverages the same engine as scoped quick-fixes, ensuring thorough issue resolution and enhancing analyzer precision. Parallel preprocessing has also been added to optimize file handling. Furthermore, you can now select the code cleanup profile per file or skip cleanup on specific files.

There are new formatting options to give you even more flexibility:

• A new option to control wrapping around an equal = operator.
• A new Indent ‘break’ from ‘case’ option.
• A new Treat ‘case’ statements with ‘break’ as simple option.

We’ve added a couple of new options to adjust naming rules more precisely.

• Local functions now come with two options: Local functions with ‘async’ and Task-returning local functions (not ‘async’).
• Methods have been given a new Task-returning method (not ‘async’) option to support methods with an async suffix in the name that aren’t marked with an async modifier but return a Task-like type. This is helpful when you declare a method in an interface where you aren’t allowed to use an async modifier, but which will return a Task type in implementation.

ReSharper 2024.3 now supports multiline To-do comments, allowing indented text on subsequent lines to be treated as part of the same To-do item. Cette amélioration facilite le regroupement des notes et des tâches associées dans votre base de code. You can now add context to your To-dos across multiple lines, improving readability and organization.

Additionally, we’ve updated the Peek To-do link (Ctrl+Shift+click) action that lets you look up an external issue associated with a To-do item inline. It now uses a modern web browser engine to give you a better rendering experience.

For this release, we reviewed almost all C# error, warning, and informal messages and introduced text colorization wherever possible.

Approximately 600 messages were updated with tooltips that offer a more intuitive reading experience, with the included code elements highlighted in the editor's familiar color scheme.

ReSharper 2024.3 inclut plusieurs améliorations de la prise en charge de C++ :

• Refactorisation Move to Folder pour les fichiers C++.
• Prise en charge des nouvelles caractéristiques des langages C++ 23, C23 et GNU.
• New code assistance features for Unreal Engine developers.
• Amélioration de l'interopérabilité avec les outils Clang.

The IL Viewer tool window now provides IL code for assembly manifest, including:

• Assembly and module info such as name, custom attributes, etc.
• Referenced assemblies and modules.
• Forwarded types.
• A list of files and resources.

This IL code is shown when the caret in the text editor is on an assembly or module attribute or somewhere inside an <AssemblyName>.cs file for external assemblies.
