More info should be included on 'add reference'

P 163 #7. Needs better explanation, this failed "dotnet add reference", got error "Required argument missing for command: reference".
Found this page, which gives more info, https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-add-reference, but decided to "modify the configuration".

P164. #4 - Not the first time that I have seen this in your book. My .cs file has "namespace CalculatorLibUnitTests;", Your example says to eliminate the ';', and put in the brackets '[]'. Is this something related to VS Code?

The dotnet add package and dotnet add reference commands were explained previously on page 157. Obviously, if you need to add a package or reference you must specify what package or reference you want--it cannot guess for you. Or, just modify the .csproj file directly as shown on page 163. This is easiest since you can just copy and paste from the ebook or from the code solution.

C# 10 and .NET 6 introduces a feature called file-scoped namespace declarations. I introduce it on page 180. It simplifies code by removing the need for curly braces { } to declare the types inside a namespace. Either the old or new syntax works correctly.

Thank you for raising this issue. In the 7th edition I will add examples of using the dotnet add commands in Chapter 1 so readers know how to use them earlier. And all the code examples will be updated to use the file-scoped namespace declaration style too.
