A lot of language features have been added over the years so you'll be missing out on some great stuff.

Also some libraries changed around a bit during the transition to .net core, so some the code in your book may not compile.

Finally, if it's a book about web dev (asp.net) or something similar (mobile dev, game dev), that stuff has changed a lot over the past ten years.

You're probably best of ditching the books and hitting up some tutorials or checking with your local library. My public library gives us access to safari books online which has a large selection of technical books.
