Question 1/64
Who already installed
Visual Studio 2019 (or used it in the Preview)?
Question 2/64
Who is regularly using C# 7 features?
If it's there - use it.
If you can't use the latest C# Umbraco at work, do it at least at home!
(unless you're working from home...)

Nah, not yet...
Works only in

(for now - why??)
What's next?!

// Won't work because FireAllDevs() is private

Always up-to-d8! What's New in C# 8?
Some developers haven't switched their manners to using the new C# 6 features yet and now we have version 7.3 and 8.0 in the preview! What’s new in the latest version? Should we be scared of the coming changes? Should we refactor current solutions or use the latest features in the next projects? For those and other questions, we will answer during this talk...
