  • ArrayExtensions: Adds useful extensions to arrays. For example, Exists() is a fluid alternative to Array.Exists().
  • CollectionExtensions: Adds ICollection<T> extensions. For example, CartesianProduct() for producing all pairs of two collections, or RemoveAll() to filter an existing collection in-place.
  • ConfigurationExtensions: Shortcuts for IConfiguration operations.
  • DictionaryExtensions: Adds IDictionary<TKey, TValue> extensions. For example, GetMaybe() for safely retrieving an item if it's in the dictionary or returning default without throwing an exception.
  • EnumerableExtensions: Adds IEnumerable<T> extensions. For example, AwaitEachAsync() for performing async operations on a collection sequentially, or AsList() for casting to List<T> without necessarily creating a new list.
  • EnumExtensions: Adds extensions for working with enum types. For example, UnknownEnumException which can be used to raise a standardized exception on the default arm of a switch.
  • ExceptionExtensions: An IsFatal() method to check if the exception is one that the application can't recover from.
  • ExpressionExtensions: Adds System.Linq.Expressions. For example, StripResult() turns a Func<T1, T2> expression into an Action<T1> one.
  • HttpContextExtensions: Some shortcuts for managing cookies.
  • IoExtensions: Adds extensions for String.IO types. For example, TextWriter.WriteLineInvariant() writes interpolated string in a culture invariant manner.
  • JsonExtensions: Adds extensions for System.Text.Json.Nodes types. For example, JsonObject.TryParse<T>(out var result) attempts to convert the JSON object into a C# object.
  • MemoryCacheExtensions: Adds extensions for IMemoryCache manipulation. For example, GetOrNew<T>() type-safely returns the item or creates a new instance.
  • MulticastDelegateExtensions: Extensions for MulticastDelegates, e.g. to invoke async delegates in a safe fashion.
  • NumberExtensions: Adds extensions for primitive numeric types. For example, ToTechnicalString() converts int into culture invariant string.
  • RandomNumberGeneratorExtensions: Shortcuts for retrieving cryptographically secure random numbers.
  • ServiceCollectionExtensions: Shortcuts to remove implementations from an IServiceCollection instance.
  • StringExtensions: Adds common useful extensions to the string type, such as SplitByCommas() and ContainsLoose().
