Code Wars C# 6 kyu: Help the Bookseller!

Beginner level C# object oriented programming series. Viewers are tasked with implementing a function that will determine how many books of each provided category are in a book collection (library). Viewers get string arrays as input, providing the categories and counts of books. The output must be formatted per the rules of the challenge as well. I'll show one solution using chained LINQ methods to solve everything. Then I'll provide another solution that uses not much LINQ at all.
