A tuple is a data structure that has a specific number and sequence of values. The Tuple`1 class represents a 1-tuple, or singleton, which is a tuple that has a single component. A singleton is used comparatively rarely in application development.

You can instantiate a Tuple`1 object by calling either the Tuple`1.#ctor(`0) constructor or the static Tuple.Create``1(``0) method. You can retrieve the value of the tuple's single component by using the read-only Tuple`1.Item1 instance property.
