In Chapter 8, in the section implementing explicit loading following the VS 2017 settings, I kept encountering
InvalidOperationException Exception: There is already an open DataReader associated with this Command which must be closed first.
anytime I tried confirming an explicit product load.

Seems to be solved by updating the connection string with MultipleActiveResultSets=True :
optionsBuilder.UseSqlServer(@"Data Source=(localdb)\mssqllocaldb;Initial Catalog=Northwind;Integrated Security=true;MultipleActiveResultSets=True;");

Page 402, also referenced on page 398. There's no "MainWindows.xaml.cs" file. I have no idea where to program this event.

TypeScript 2.7 introduced strictPropertyInitialization which breaks 'home.component.ts' in the ExporeAngular example in Ch16, page 635, as 'customers' generates this error: [ts] Property 'customers' has no initializer and is not definitely assigned in the constructor.

Fix: add: "strictPropertyInitialization": false, to tsconfig.json and restart VSCode.

As I'm going through the book I begin to understand that this repo is going to be a valid source of reference in the future. Would that be a possibility to comment everything professionally through a lens of a teacher? Maybe add some bonus insight that is not explicitly covered in the book?
