When you design APIs that return large datasets, pagination is not optional. Without it, you risk overwhelming your database, your network, and your consumers.

In #dotnet 10, DATAS is enabled by default. The GC now adjusts heap thresholds to match the actual app memory needs.

✅ Light load → GC frees memory aggressively
✅ Heavy load → heap expands on demand
⚠️ May raise p99 latency in spiky workloads.

⚡In .NET 9, even tiny arrays hit the heap, adding GC overhead. In .NET 10, if an array never leaves the method, it’s stack‑allocated. Result → ~2× faster, 0 allocations, less GC pressure.

.NET 10 GC tuning demonstrates how stack allocations, DATAS, and region sizing reduce allocations, improve latency, and lower your cloud costs.

In C# 14, you can provide custom behavior for compound assignments like `+=`, `-=`, etc..

No thank you 😂

Fancy more partial members in C#? How about constructors and events? 😏

We can now write an accessor body that uses the compiler-synthesized backing field with no explicit private field. 🎉🎉🎉

In C# 14, you can now add 'out', 'ref', 'in', 'scoped', or 'ref readonly ' to simple lambda parameters without specifying types.

The C# 14 compiler now recognizes common conversions (T[] → Span, string → ReadOnlySpan, etc.) This reduces the need for explicit `.AsSpan()` calls and improves overload resolution.

This is one of those small life improvements in C# 14 that bothered me for years, and I'm really glad they've finally fixed it. 😍
You can pass an unbound generic type to `nameof`.

🎉 Finally in C# 14, the null-conditional operators `?.` and `?[]` now work on the left side of = (and compound assignments). The RHS is only evaluated when the LHS isn’t null.

🪞 Code Cloning & Specialization
JIT duplicates code paths:
• Fast path = 1 length check
• Fallback = full safety
Now works for spans & foreach try/finally. #dotnet

Roxeem @roxeem.com · Sep 13

📏 Bounds‑Check Elimination
Smarter JIT removes redundant checks using constants, merged assertions, switch‑case analysis & span patterns. Smaller code, faster loops. #dotnet

Roxeem @roxeem.com · Sep 13

🔍 Devirtualization
Array interface calls (IList, IEnumerable) now devirtualize. Loops & LINQ ops run up to 70% faster. Dynamic PGO + extra inlining = even more speed. #dotnet

🗑 JIT Deabstraction + Stack Allocation
Escape analysis now stack‑allocates more objects, delegates, arrays & spans.
Fewer heap allocs, less GC pressure, up to 66% faster in common patterns. #dotnet
