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.

When you design APIs that return large datasets, pagination is not optional. Without it, you risk overwhelming your database, your network, and your consumers. #dotnet #aspnet https://roxeem.com/2025/10/11/strategic-pagination-patterns-for-net-apis

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 https://roxeem.com/2025/09/30/what-net-10-gc-changes-mean-for-developers/

.NET 10 GC tuning demonstrates how stack allocations, DATAS, and region sizing reduce allocations, improve latency, and lower your cloud costs. #dotnet #csharp #gc #performance https://roxeem.com/2025/09/30/what-net-10-gc-changes-mean-for-developers/

In C# 14, you can provide custom behavior for compound assignments like `+=`, `-=`, etc.. #csharp #dotnet #dotnet10

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. 🎉🎉🎉 #csharp #dotnet #dotnet10 https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-14#the-field-keyword

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 https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-14#the-field-keyword

In C# 14, you can now add 'out', 'ref', 'in', 'scoped', or 'ref readonly ' to simple lambda parameters without specifying types. #csharp #dotnet #dotnet10

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

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`. #csharp #dotnet #dotnet10 https://roxeem.com/2025/08/30/c-14-will-change-how-you-code-heres-why/

🎉 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 https://roxeem.com/2025/08/30/c-14-will-change-how-you-code-heres-why/

In C# 14, you can now declare extension properties, indexers, and even static extension members on a type. #dotnet #csharp #dotnet10 roxeem.com/2025/08/30/c...

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

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