How to stop worrying and adopt nullable reference types – Webinar Recording

Maarten Balliauw

The recording of our July 9 webinar, How to stop worrying and adopt nullable reference types, with Andrey Dyatlov, is now available. Subscribe to our community newsletter to receive notifications about future webinars.

Nullable reference types is a deceptively simple feature. While starting with it is as easy as adding a single ? mark to your source code, migrating large code bases has been proven to be a tedious and sometimes quite tricky task especially when complex code contracts and generics are involved.

The presentation will quickly cover what benefits this feature brings to the table, how it differs from JetBrans.Annotations attributes and how it evolved since its original release almost a year ago.

I will show a couple of ways to ease migration of large code bases to nullable reference types and how you can start to benefit from the feature immediately without putting any effort into annotating your code base just yet. I will also outline the most common pitfalls and explain how to deal with generics and potential analysis shortcomings as well as how to guide the compiler through complex code contracts to get the most out of this feature.
