Some of you may also have problems with returned JSON numerical values being too big to fit into an Integer variable due to the growth of Betfair's ID values. Other than that work your way through the rest of this page to find addenda to correct past changes that Betfair and Microsoft have made that impacted on the book. Thank you to Malcolm for providing that alert. I have been notified that Microsoft has made a change to Visual Studio such that on page 37 Today.IsDaylightSavingTime() should now be Now.IsDaylightSavingTime() for those of you in countries that use daylight saving time. Update, March 2018 - The book is still selling well as the best reference for learning how to use Betfair's API-NG. They are there because my code still works!

Again, before contacting me to debug your code, check the errata below and then check your code for typos. Update, January 2019 - I never thought the book would still be selling three and a half years later but it is! The code is still robust, save for one new correction in the MarketBook class, which I include in the errata below.
