#02 Brave New Nullless World in C# 10

Beyond nullable (I mean: non-nullable) reference types, null coalescing and null propagation operators in C#, closing the outer door for nulls in only the first step in securing your models from missing and nonexistent objects. A much larger work is only to begin, and that is to develop a proper object model which never issues a null, nor ever fails due to receiving one from the outside.
In this session, we will outline the place for the null-related C# syntax in domain modeling. Then, we will revisit often overlooked patterns: polymorphic models and optional objects. With these tools put together and enforced with latest language syntax, you will never want to return to using null references.
