Nullable Reference Types in C# 8

Nullable Reference Types in C# 8

Explore nullable reference types in C# 8 through this comprehensive conference talk by Jon Skeet at GOTO Copenhagen 2019. Dive deep into the syntax, purpose, and expectations of this major feature, including potential surprises. Learn about nullable local variables, arrays, strings, and variables, as well as the efficiency of null and how to handle null reference exceptions. Discover the null-forgiving operator, precondition tests, and the responsible approach to warnings as errors. Gain insights on unguarded mutation, copypaste issues, and the implications of non-nullable references. Understand the concept of nullable strings, default values, and annotations while considering whether the CLR could have changed to accommodate this feature.
