Async ValueTask Pooling in .NET 5

Stephen Toub - MSFTMarch 16, 2020Mar 16, 202003/16/20

The async/await feature in C# has revolutionized how developers targeting .NET write asynchronous code. Sprinkle some async and await around, change some return types to be tasks, and badda bing badda boom, you've got an asynchronous implementation. In theory. In practice, obviously I've exaggerated the ease with which a codebase can be made ...

.NET added async/await to the languages and libraries over seven years ago. In that time, it's caught on like wildfire, not only across the .NET ecosystem, but also being replicated in a myriad of other languages and frameworks. It's also seen a ton of improvements in .NET, in terms of additional language constructs that utilize asynchrony, ...

Postal drivers delivering mail all along their routes, and you ...

We open sourced our new GC Perf Infrastructure! It’s now part of the dotnet performance repo. I’ve been meaning to write about it ‘cause some curious minds had been asking when they could use it after I blogged about it last time but didn’t get around to it till now. First of all, let me point out that the target audience of this ...

Hardware Intrinsics in .NET Core

Tanner Gooding [MSFT]September 3, 2019Sep 3, 201909/3/19

Several years ago, we decided that it was time to support SIMD code in .NET. We introduced the System.Numerics namespace with Vector2, Vector3, Vector4, Vector<T>, and related types. These types expose a general-purpose API for creating, accessing, and operating on them using hardware vector instructions (when available). They also ...
