Linq has been a part of C# since version 3. It is not a separate library. Using linq means you are writing functional code. If you are a beginner, you should try writing loops to understand programming but I would never use a loop to find an item in a collection in production code.

Thanks!

I'm getting this error for the C# solution. Please fix the issue.

There are some warnings in the C# solution about unused member fields in the tests which are assigned but not used.

This kata has a compilation issue in C#. Please fix it.
