Acknowledgments
I WANT TO THANK Charlotte Kughen, who made my text so much
more readable. Often I was working late at night writing while .NET
Core was continuously evolving. Charlotte was of enormous help to
change my ideas into great readable text. I’m almost sure that Charlotte
now knows a lot more about programming than she would like to.
Special thanks also goes to István Novák, who has authored several
great books. Despite all the issues we had with the fast-evolving .NET
Core and the interim builds I was using while working on the book,
István challenged me to enhance the code samples that allow you—the
reader—to better follow the flow. Thank you, Charlotte and István—
you’ve been of great help for the quality of this book.
I also would like to thank Kenyon Brown and Jim Minatel and everyone
else at Wiley who helped to get edition 10 of this great book to be
published. I also want to thank my wife and children for supporting my
writing. You understood and helped with the time I was working on the
book, including evenings, nights, and weekends. Angela, Stephanie, and
Matthias—you are my loved ones. This would not have been possible
without you.
