C# choices, Redis, pgvector, LINQ
Covers watermarking, StringBuilder tradeoffs, DI, Redis, pgvector search, LINQ pitfalls, primary constructors, and AI-assisted security checks.
Jasen's top three picks
- 1 How to Add a Watermark to an Image in C# ?
""charp" OR "asp.net" OR "fsharp" OR "c#" OR "vb.net" " - Google News
A basic but useful image-processing walkthrough for anyone who needs quick watermarking in everyday C# utilities or web back ends.
- 2 Difference Between String and StringBuilder in C# and When to Use Each?
C# Corner
A familiar topic, but still worth revisiting because string allocation mistakes quietly add up in hot paths and loops.
- 3 Dependency Injection in .NET
Medium
A straightforward dependency injection primer that fits newer .NET developers or anyone brushing up on composition basics.
Editor's note
I pulled together another deliberately mixed issue today, which is how I like this newsletter to read. The pgvector walkthrough stands out because it shows a practical path to lightweight vector search without extra infrastructure, and the LINQ pitfalls piece is a useful reminder that small abstractions can have real performance costs. There’s also a solid spread of core C# language material here, from primary constructors to record structs and functional patterns.
