Java user here. What is a good book/set of resources on getting started in .NET/C#, possibly this version 6, without knowing the ecosystem beforehand (but with a experience in programming)? Thanks!
There's also a 40 page e-book ".NET for Java developers" here: https://aka.ms/dotnet-forjavadevs
I can, however, recommend you use Rider as your IDE. It includes JetBrains' excellent ReSharper code analysis tool, which actually corrects a lot of your generic OO code and will automatically rewrite it for you to be more idiomatic (avoiding memory and performance issues, for example). Rider knows the sharp edges so you can mostly forget about them.
Otherwise it should be very easy for you to pick up. .NET has some annoying code organization conventions (lots of subprojects, too many folders, etc.) but you can just structure your project however makes sense for you and avoid all of that.
If you feel like you really need a book, this one is good: https://www.packtpub.com/product/c-10-and-net-6-modern-cross...
