Summary

There is no doubt that the new C# 8 features mark an important milestone in terms of code robustness and clarity. It is not unusual for a language to become (version after version) more complex and difficult to read, but C# introduced features such as pattern matching and ranges that allow any developer to express their intent with more concise and unambiguous code.

While it is controversial, the default interface members introduced the Traits paradigm to the .NET world and addressed problems such as interface versioning, which caused developers to struggle for years.

We learned about a key feature, that is, built-in nullable reference static code analysis, which allows us to progressively review the code and dramatically cut down the number of errors due to dereferencing null references.

This was not the end of tuning the language for productivity, as we continued through the C#7 performance journey with asynchronous streams, read-only struct members, and the updates...
