Incremental Source Generators in .NET In this post, I'll show you what Roslyn source generators are, why they're a massive improvement over old techniques, and how to build a simple, high-performance generator from scratch.

An introduction to #dotnet Source Generators. How to eliminate boilerplate, boost performance, and replace runtime reflection with compile-time code generation.

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.

#dotnet #csharp #performance

⚡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.

#dotnet #csharp

.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..

#csharp #dotnet #dotnet10

No thank you 😂

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

#csharp #dotnet #dotnet10

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

Hey #dotnet engineers and enthusiasts. Let's connect 🙂

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

#csharp #dotnet #dotnet10

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

#csharp #dotnet #dotnet10

First-class Span<T> conversions

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.

#csharp #dotnet #dotnet10

nameof supports unbound generics

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`.

Stop treating prompts like magic spells. Treat them like software. Orchestrate, secure, and scale your AI workflows with real engineering.

🎉 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.

#dotnet #csharp #dotnet10

Extension members (instance and static)

In C# 14, you can now declare extension properties, indexers, and even static extension members on a type.
#dotnet #csharp #dotnet10

Lucky you! Hope nothing broke 😉

To all the software developers and problem solvers: Happy #ProgrammersDay! 🎉

Performance Improvements in .NET 10 - .NET Blog Take a tour through hundreds of performance improvements in .NET 10.

That’s the .NET 10 perf story. Now go and read Stephen Toub's yearly novel to understand the juicy parts 😉
devblogs.microsoft.com/dotnet/perfo...

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

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

🔍 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

🚀 .NET 10 RC1 is here, and it’s time for another Stephen Toub novel. But to summarize, this is what has changed:
