The next video in my exploring MoreLINQ series covers a few extension methods that allow us to insert elements into an existing sequence. The first two, Append and Prepend, allow you to insert a single element at the start or end of a sequence, and are so useful that they are now part of the official .NET Framework (from version 4.7.1 onwards).

Then there's also Insert and Backsert, which allow you to insert a sequence at a particular location within an existing sequence, counting either from the start (Insert) or the end (Backsert).

You can find all videos in this series here.
