Too Long; Didn't Read
Microsoft added a lot of new syntax goodies in their latest release of C# 8.0. The index from the end operator and var var are easier to understand and shorter. Using variables are handy to make sure that disposable resources don't outlive the scope of the method where they are instantiated. Verbatim strings @ and string interpolation $ are two useful concepts to build string literals. You can now specify them in any order, and the compiler will figure it out for you.
