In November 2019, we announced .NET support for Jupyter notebooks with both C# and F# support. Today we are excited to announce Preview 2 of the .NET Notebook experience. In this article you can find all the major new features of this release. Join us!

Welcome to what's new in .NET docs for January 2020. This article lists some of the major changes to docs during this period.

I’m excited to announce experimental support for gRPC-Web with .NET. gRPC-Web allows gRPC to be called from browser-based apps like JavaScript SPAs or Blazor WebAssembly apps.

gRPC-Web for .NET promises to bring many of gRPC’s great features to browser apps:

• Strongly-typed code-generated clients
• Compact Protobuf messages
• Server streaming

Today we released a new preview update for Blazor WebAssembly with a bunch of great new features and improvements.

Here’s what’s new in this release:

• Version updated to 3.2
• Simplified startup
• Download size improvements
• Support for .NET SignalR client

Versions 16.3 and 16.4 of Visual Studio 2019 brought many new improvements in code generation quality, build throughput, and security. If you still haven’t downloaded your copy, here is a brief overview of what you’ve been missing out on.

Last week, Visual Studio 2019 version 16.5 Preview 2 was released, bringing many new features and improvements for developers in Visual Studio to help you build better software faster. Please read some highlights of new features and improved developer experiences in this page.



Install this preview side-by-side with your Visual Studio release and try these highlighted features without replacing your current development environment.

Visual Studio 2019 versions 16.3 and 16.4 include improvements to the C++ inliner. Among these is the ability to inline some routines after they have been optimized, referred to as the «Zipliner.» Depending on your application, you may see some minor code quality improvements and/or major build-time (compiler throughput) improvements. 

We are pleased to announce that the January 2020 release of the Python Extension for Visual Studio Code is now available. You can download the Python extension from the Marketplace, or install it directly from the extension gallery in Visual Studio Code. If you already have the Python extension installed, you can also get the latest update by restarting Visual Studio Code. You can learn more about  Python support in Visual Studio Code in the documentation.

The great debates in computing all have one common theme. Whether it is tabs vs. spaces or Vi vs. Emacs, the thread linking all these debates together is keyboard efficiency. The truth is, we spend tons of hours working in an application, and keyboard shortcuts become automatic to us, the same muscle memory that great pianists or sports players have. If you suddenly give a virtuoso pianist a piano where the keys are half as wide and the sharp/flat keys are below as opposed to above the natural keys, they will struggle to make even the most basic melodies while they learn the new arrangement. Likewise, when it comes to keyboard shortcuts in your favorite IDE, any change can be disorienting quickly. Luckily, Visual Studio for Mac offers a ton of customizations to key bindings that will allow you get configure your key combinations to your liking.

Hyper-V is more known as a server virtualization technology; however, since Windows 8, it is also available in the client operating system. In Windows 10, Microsoft improved the experience drastically to make Hyper-V an excellent solution for developers and IT Pros.
 
Microsoft Hyper-V, codenamed Viridian, is a native (type 1) hypervisor that directly runs on the hardware, compared to VMware Workstation, VirtualBox, and other type 2 or hosted hypervisors. It was first released in Windows Server 2008, and it allows you to run virtual machines on x86-64 systems.

As mentioned, with Windows 10, Microsoft optimized Hyper-V for developers. Hyper-V allows developers to quickly spin up development virtual machines on Windows 10 with excellent performance, but it is also used in a couple of other development features as a back-end technology, like the Android Emulator, the Windows Subsystem for Linux 2 or Docker Containers. In this article, we will have a quick look at what Hyper-V on Windows 10 can over for developers.

If you've been thinking about learning C#, now is the time to jump in! I've been working on this project for months and I'm happy to announce http://dot.net/videos 

There's nearly a hundred short videos (with more to come!) that will teach you topics like C# 101, .NET, making desktop apps, making ASP.NET web apps, learning containers and Dockers, or even starting with Machine Learning. There's a ton of great, slow-paced beginner videos. Most are less than 10 minutes long and all are organized into Playlists on YouTube!

If you are getting started, I'd recommend starting with these three series in this order — C#, .NET, then ASP.NET. After that, pick the topics that make you the happiest.

We’re announcing the preview of Azure Spot Virtual Machines. Azure Spot Virtual Machines provide access to unused Azure compute capacity at deep discounts. Spot pricing is available on single Virtual Machines in addition to Virtual Machine Scale Sets (VMSS). This enables you to deploy a broader variety of workloads on Azure while enjoying access to discounted pricing. Spot Virtual Machines offer the same characteristics as a pay-as-you-go Virtual Machines, with differences in pricing and evictions. Spot Virtual Machines can be evicted anytime if Azure needs capacity.

The workloads that are ideally suited to run on Spot Virtual Machines include, but are not necessarily limited to, the following:

• Batch jobs.
• Workloads that can sustain and/or recover from interruptions.
• Development and test.
• Stateless applications that can use Spot Virtual Machines to scale out, opportunistically saving cost.
• Short-lived jobs which can easily be run again if the Virtual Machine is evicted.

We were speaking with a customer last year that builds dozens of mobile applications every year. They said, «We cannot remember the last time we made a mobile app that did NOT include a carousel view.» Many of you have expressed almost identical sentiments to us. So, we are very pleased to introduce a new CarouselView control in Xamarin.Forms 4.4.0. Along with this we also have IndicatorView for displaying the pages or items in the carousel. As well as SwipeView for providing contextual actions to any element in a CollectionView. The release theme of getting things moving would not be complete without showcasing the new GIF animation support for images. Let’s begin right there.

В .NET Core 3 появился новый шаблон проекта под названием Worker Service. Этот шаблон разработан, чтобы дать вам отправную точку для создания кроссплатформенных сервисов. В качестве альтернативного варианта использования: он дает очень хорошую среду для создания консольных приложений, которая идеально подходит для контейнеров и микросервисов.



Подробнее о некоторых из преимуществ использования этого шаблона читайте под катом.

Premier Developer Consultant Randy Patterson discusses the benefits of using the new Worker Service project template introduced in .NET Core 3.

.NET Core 3 introduced a new project template called Worker Service. This template is designed to give you a starting point for cross-platform services. As an alternate use case, it sets up a very nice environment for general console applications that is perfect for containers and microservices.



Some of the benefits of using this template include the following areas.

Прошло уже больше 2 лет с момента первого публичного выпуска языка квантового программирования Q#. К случаю годовщины ребята из команды Q# подготовили рассказ про второй год этого развития. Читайте о нем под катом!

Remember How We Started

Our first release of our second year, 0.4, was a triumph! we got a customer request for a big integer type on January 1st, and were able to respond by shipping a new BigInt data type just 29 short days later!!! Remember, we’re outside Seattle, pretty far north, so our winter days are really short.

Our secret? We had started working on the BigInt type in December.

We also decided to change our release cadence for our second year of Q#. Our first year, we had shipped releases sporadically, when we had some major feature to share, or possibly just a fix to an annoying bug. For our second year, we moved to a more regular release cadence, putting out a new release every month. We hoped that this would make things more predictable for our users and easier for us to manage.

More than 100 Azure services offer everything you need to build and run your applications with all the performance, redundancy, security, and scale that the cloud has to offer. But knowing where to begin with all these services can seem overwhelming. 

Read this e-book to build your cloud computing skills quickly and efficiently. You’ll be productive immediately, and when you finish, you’ll be well on your way to Azure mastery.

Another release is out for the Windows Terminal preview! This release is labeled as v0.7 in the About section of the Terminal. As always, you can download the Terminal from the Microsoft Store and from the GitHub releases page. Here’s what’s new in this release:

Windows Terminal Updates

Panes

You are now able to split your Terminal window into multiple panes! This allows you to have multiple command prompts open at the same time within the same tab.

Note: At the moment, you’re only able to open your default profile within a new pane. Opening a profile of your choice is an option we’re planning to include in a future release!
