C# 14 features, agentic AI, and SQL Server search
This issue covers C# 14 updates, ASP.NET Core binding, EF Core architecture, agentic AI, and SQL Server vector search, plus testing and patterns.
Jasen's top three picks
- 1 The best new features of C# 14
news.google.com
A solid look at what’s new in C# 14, and why it matters for everyday language work rather than just release-note trivia.
- 2 Dealing with DB Null: Solving the Object cannot be cast from DB Null to other types Error in C#
c-sharpcorner.com
A practical reminder that DBNull handling still bites real applications; the examples here are useful for any database-heavy codebase.
- 3 How to Reverse a String in C#
c-sharpcorner.com
Simple topic, but string reversal is a good way to think about APIs, immutability, and when micro-optimizations actually matter.
Editor's note
I put together a pretty wide mix this time: language updates, core framework fundamentals, architecture, and a strong AI/data streak. The C# 14 piece and the SQL Server vector-search demo stand out because they show where the platform is headed, while the DBNull and binding-source articles are the kind of practical refreshers people still need.
