Pieter Le Roux      | 18          | 776         | errorMessage listed twice in listing 18.3

Pieter Le Roux      | 16          | 712         | Output 16.3 is missing "when"

If needed to access pre C# 7.0 listing, can just switch branches

Pieter Le Roux      | 16          | 719         | Add "when" to Output 16.6 ("when*" was missing from source code)

Pieter Le Roux      | 16          | 721         | Add "when" to Output 16.7 ("when*" was missing from source code)

Update Line 23 "\t" that doesn't match Output 15.9

Pieter Le Roux      | 16          | 686         | tabs in Output 15.9 doesn't reflect Listing 15.21. Fixed by updating source code

Updated comment in source code

Pieter Le Roux      | 16          | 700         | // ERROR: Cannot implicitly convert type // 'AnonymousType<s>#3</s>#1' to 'AnonymousType<s>#2</s>#3'

Otherwise list.Remove("Grumpy") will now cause Console.WriteLine to throw a run-time error if not corrected

Pieter Le Roux      | 16          | 733         | Saw List[6] could throw error. Changed to "{ List[<s>6</s>^1] }

Pieter Le Roux      | 16          | 725         | in Listing 16.16 and Listing 16.17, add "!" prior to "word. Contains('*')" to match Listing 16.01

Pieter Le Roux      | 19          | 824         | "The worker thread will write <s>periods</s>plus signs to the console

Pieter Le Roux      | 17          | 760         | "as you did in both CSharp<s>PrimitiveTypes</s>BuiltInTypes"
