The type of key to compare elements by.
A sequence of values to determine the minimum value of.
A function to extract the key for each element.
The IComparer<T> to compare keys.
The CancellationToken to monitor for cancellation requests. The default is None.
The value with the minimum key in the sequence.

No key extracted from source
implements the IComparable or IComparable<T> interface.
If TKey
is a reference type and the source sequence is empty or contains only values that are null
