Could someone please show/describe an appropriate use of the System.Tuple class?
I have looked on MSDN and the description there doesn't show any practical uses.

From the MSDN on the 2-tuple:
A tuple is a data structure that has a specific number and sequence of values. The Tuple class represents a 2-tuple, or pair, which is a tuple that has two components. A 2-tuple is similar to a KeyValuePair structure.
In the Tuple<T1, T2> case, It is a generalization of the KeyValuePair<,> data structure.
Tuples are basically generic data structures. You can use them to avoid defining your own structure. An example would be for returning multiple values from a function.
It is a very useful tool in function-oriented/functional programming.
