Compares arrays for equality by element.

Utility functions for manipulating collections.

A covariant list converts a list of the input type to a read-only list of the more generic output type. The wrapped list can be used to mimic covariance in method return types.

Provides a singleton empty array instance.

A read-only empty dictionary.

Encapsulates various strategies for counting the number of elements in a collection, an array, or a simple enumerable type.

Utility functions for manipulating generic collections.

A hashtable-based set implementation.

Lazily populates and caches values associated with a particular key.

A multi-map allows a list of values to be associated with a single key.

A property bag associates keys with values where each key may have one or more associated value. All keys and values must be non-null strings.

A property set associates keys with values where each key may have exactly one associated value. All keys and values must be non-null strings.

A read-only dictionary wrapper.

An equality comparer that compares values by reference.

Provides functions for manipulating ad-hoc trees.

A user data collection stores arbitrary key/value pairs that may be associated with other objects in the system.

A strongly-typed key to be used together with an associative array to help the compiler perform better type checking of the value associated with the key.

Represents a strategy for counting the number of elements in a collection, an array, or a simple enumerable type.

A multi-map allows a list of values to be associated with a single key.

Contains a PropertySet

Enumerates child nodes in a tree.

Name of the existing counting strategies.
