- 1 Inline Arrays in C# 13: The Secret Performance Feature You’re Probably Ignoring
medium.com
A small language feature with an outsized payoff: inline arrays can remove allocations in hot paths without rewriting your whole design.
- 2 The Best Way to Write Parameterized Tests in .NET Using xUnit (Clean, Fast, and Not Annoying)
medium.com
A clean xUnit parameterized-testing approach is worth reading if you want less ceremony and more readable test cases.
- 3 Introducing C# 14
devblogs.microsoft.com
C# 14 is the headline runtime/language update here, with the .NET 10 connection making it especially relevant for planning upgrades.
Editor's note
I curated a pretty wide mix today, from language and runtime updates to tooling, data, and security. The C# 14 announcement and the inline arrays piece both stand out for developers who care about what ships next and what helps right now. I also liked the Azure SQL vector indexing preview because it hints at practical search and AI workloads without leaving the .NET stack.
