The specification defines many floating point types, including: , , and . Most developers are familiar with (equivalent to in C#) and (equivalent to in C#). They provide a standard format to represent a wide range of values with a precision acceptable for many applications. .NET has always had and and with .NET 5 Preview 7, we've added a ne...
Last month, we announced .NET support for Jupyter notebooks, and showed how to use them to work with .NET for Apache Spark and ML.NET. Today, we're announcing the preview of a DataFrame type for .NET to make data exploration easy. If you've used Python to manipulate data in notebooks, you'll already be familiar with the concept of a DataFrame. At a...
Blazor Server in .NET Core 3.0 enables you to add rich interactive UI to your .NET apps without having to write JavaScript. Learn about when to use Blazor Server, how it scales, how it relates to Blazor WebAssembly, and how we expect to evolve Blazor in the future.
It's about two years ago that I announced .NET Standard 2.0. Since then we've been working hard to increase the set of .NET Standard-based libraries for .NET. This includes many of the BCL components, such as the Windows Compatibility Pack, but also other popular libraries, such as the JSON.NET, the Azure SDK, or the AWS SDK. In this blog post, I'l...
For .NET Core 3.0, we're shipping a brand new namespace called System.Text.Json with support for a reader/writer, a document object model (DOM), and a serializer. In this blog post, I'm telling you why we built it, how it works, and how you can try it. We also have a video: Getting the new JSON library The future of JSON in ....
Typically, calendar eras represent long time periods. In the Gregorian calendar, for example, the current era spans (as of this year) 2,019 years. In the Japanese calendar, however, a new era begins with the reign of a new emperor. On April 30, 2019, Emperor Akihito is expected to abdicate, which will bring to an end the Heisei era. On the followin...

Starting back with the .NET Core 2.1 release, we were making iterative improvements to the floating-point parsing and formatting code in .NET Core. Now, in .NET Core 3.0 Preview 3, we are nearing completion of this work and would like to share more details about these changes and some of the differences you might see in your applications. The prim...

Developing applications that span multiple operating systems in .NET Core while working with Time Zone information can lead to unexpected results for developers not familiar with the differences in how operating systems manage Time Zones. In this post, we will explore those differences and the challenges they present. Reproducing the issue Suppos...
Building C# 8.0 The next major version of C# is C# 8.0. It's been in the works for quite some time, even as we built and shipped the minor releases C# 7.1, 7.2 and 7.3, and I'm quite excited about the new capabilities it will bring. The current plan is that C# 8.0 will ship at the same time as .NET Core 3.0. However, the features will start to ...
