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 ...

Default implementations in interfaces

Mads TorgersenMay 14, 2019May 14, 201905/14/19

Default implementations in interfaces With last week's posts Announcing .NET Core 3.0 Preview 5 and Visual Studio 2019 version 16.1 Preview 3, the last major feature of C# 8.0 is now available in preview. A big impediment to software evolution has been the fact that you couldn't add new members to a public interface. You would break ...

An update to C# versions and C# tooling

Phillip CarterFebruary 27, 2019Feb 27, 201902/27/19

Starting with Visual Studio 2019 Preview 4, we'll be adjusting how C# versions are treated in .NET tooling. Firstly, we're adding two new Language Version (LangVersion) values: LatestMajor and Preview. Rad the post to see how they stack up with the currently supported list of values.

Mads Torgersen - MSFTJanuary 24, 2019Jan 24, 201901/24/19

Do more with patterns in C# 8.0 Visual Studio 2019 Preview 2 is out! And with it, a couple more C# 8.0 features are ready for you to try. It's mostly about pattern matching, though I'll touch on a few other news and changes at the end. More patterns in more places When C# 7.0 introduced pattern matching we said that we expected to add more ...

Introducing Nullable Reference Types in C#

Mads Torgersen - MSFTNovember 15, 2017Nov 15, 201711/15/17

Today we released a prototype of a C# feature called "nullable reference types", which is intended to help you find and fix most of your null-related bugs before they blow up at runtime. We would love for you to install the prototype and try it out on your code! (Or maybe a copy of it! 😄) Your feedback is going to help us get the feature ...

Welcome to C# 7.2 and Span

Mads Torgersen - MSFTNovember 15, 2017Nov 15, 201711/15/17

C# 7.2 is the latest point release of C#, and adds a number of small but useful features. All the features are described in wonderful detail in the docs. Start with the overview, What's new in C# 7.2, which gives you an excellent introduction to the new set of capabilities. It is worth celebrating that a significant portion of the docs are ...

Welcome to C# 7.1

Mads Torgersen - MSFTOctober 31, 2017Oct 31, 201710/31/17

With C# we have always tended towards major releases: bundle a lot of features up, and release less frequently. We even went so far as routinely omitting the traditional ".0" when we talked about C# 6.0! In the C# 7.0 "wave" we are trying something new. Tools such as Visual Studio upgrade on a frequent cadence, and there's no longer a ...

The .NET Language Strategy

Mads Torgersen - MSFTFebruary 1, 2017Feb 1, 201702/1/17

The .NET Language Strategy I am constantly aware of the enormous impact our language investments have on so many people's daily lives. Our languages are a huge strength of the .NET platform, and a primary factor in people choosing to bet on it - and stay on it. I've been here on the .NET languages team at Microsoft for more than a decade, and...
