Good books on VB:net and rpa

I’m interested in learning more about the less evident features of UiPath which come from VB.net. I’ve been using small things like ternary operators, but would like to know more about namespaces and such. Can anybody point me to a direction? It doesn’t have to a book.

First one I found on VB.Net for beginners is “Programming visual basic .net” by David Grundgeiger. Seems like a great guide for starting VB.net
