The ReCommended Extension for ReSharper augments the sophisticated code analysis engine by providing more rules not (yet) available from JetBrains. Among the most interesting features are

• advanced disposable object analysis built around the [MustDisposeResource] and [HandlesResourceDisposal] annotations,
• detection of more cases when collection expressions can be used,
• detection of redundant assertions,
• inappropriate use of async void,
• exception analyzer (exceptions that should never be thrown or caught, exceptions thrown in unexpected locations),
• array initializers (empty arrays or arrays initialized with default values),
• await expression analyzer (add .ConfigureAwait(false) for last expressions),
• ValueTask/ValueTask<T> analyzer (possible multiple consumption),
• incorrect use of ArgumentException constructor parameters,
• locking on weak identity objects,
• using yield return inside the lock blocks,
• incorrect use of ReSharper annotations,
• and lots more.

The most highlightings also have quick fixes for obvious solutions.

Another feature of the extension are new context actions that simply save time for accomplishing everyday tasks, e.g. for adding ReSharper annotations, adjusting XML doc comments, setting language injections, etc.
