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...

Deprecating TLS 1.0 and 1.1 on NuGet.org
co-authored by Scott Bommarito At Microsoft, using the latest and secure encryption techniques is very important to us to ensure the security and privacy of our customers. TLS 1.0 and TLS 1.1, released in 1999 and 2006 respectively, are known to be vulnerable to a number of attacks including POODLE and BEAST. In the past, we removed support for SSL 3 because it was also vulnerable to attacks. For those reasons, NuGet.org will be removing support for TLS 1.0 and 1.1. This means that you will no longer be able to restore packages, upload packages, or browse NuGet.org using these outdated security protocols. Th...
