Announcing .NET Core 3.1

Announcing .NET Core 3.1 We’re excited to announce the release of .NET Core 3.1. It's really just a small set of fixes and refinements over .NET Core 3.0, which we released just over two months ago. The most important feature is that .NET Core 3.1 is an long-term supported (LTS) release and will be supported for three years. As we've done in the past, we wanted to take our time before releasing the next LTS release. The extra two months (after .NET Core 3.0) allowed us to select and implement the right set of improvements over what was already a very stable base. .NET Core 3.1 is now ready to be used wherever yo...
Embracing nullable reference types
Probably the most impactful feature of C# 8.0 is Nullable Reference Types (NRTs). It lets you make the flow of nulls explicit in your code, and warns you when you don't act according to intent. The NRT feature holds you to a higher standard on how you deal with nulls, and as such it issues new warnings on existing code. So that those warnings (however useful) don't break you, the feature must be explicitly enabled in your code before it starts complaining. Once you do that on existing code, you have work to do to make that code null-safe and satisfy the compiler that you did. How should you think about when...
