With the release of C# 10.0 comes a host of coding choices that are non-trivial to resolve. Questions such as when to use a record class rather than just a class, should I ever declare a struct rather than a record struct, what about global using statements vs project elements, or should I ever not use file scoped namespace declarations. C# 8 .0 & 9.0 include raise similar questions such as when is a protected interface member relevant, how does one declare a non-nullable property without incurring C# warnings (and does C# 11.0 help with this). The recent C# feature additions seems simple at first but there are numerous idiosyncrasies to wrestle with. Don't miss out on this session to understand the internals of modern day C# and how and when to best leverage these features and what C# 8.0-11.0 provides to improve the language.
