Tuples have not been newly introduced in the current version but were introduced with the .NET 4.0 release. In the present release, they have been improved.

Tuples

Tuples are there at whatever point a particular case needs to return multiple values from a method. For instance, let's say we have to find odd and even numbers from a given number series.

For a method that will return these multiple values, we could use custom datatypes, dynamic return types, or out parameters, which sometimes will create confusion for a developer.
