Today, we’re happy to announce the Generally Available (GA) release of PowerShell 7.0! Before anything else, we’d like to thank our many, many open-source contributors for making this release possible by submitting code, tests, documentation, and issue feedback. PowerShell 7 would not have been possible without your help.

What is PowerShell 7?

For those unfamiliar, PowerShell 7 is the latest major update to PowerShell, a cross-platform (Windows, Linux, and macOS) automation tool and configuration framework optimized for dealing with structured data (e.g. JSON, CSV, XML, etc.), REST APIs, and object models. PowerShell includes a command-line shell, object-oriented scripting language, and a set of tools for executing scripts/cmdlets and managing modules.

^{«Clean Code» and a clean cat}

There is nothing developers enjoy better than arguing about clean code: Dan Abramov, for example, has recently fueled the hype with his blog post, «Goodbye, Clean Code».

However, “clean code” per se doesn’t even have a clear definition. The main book on the subject is Clean Code, where Robert «Uncle Bob» Martin states that there are perhaps as many definitions as there are programmers. But he doesn’t walk away from the fact with a conclusion that there’s no reason to discuss clean code, rather — compare several definitions and highlight general ideas. Therefore he cites the views of several outstanding programmers on what clean code is.

So we have also become interested in what people in 2020 think of clean code. Have the views changed since the publication of the book? Do opinions vary in different IT fields (maybe backend developers perceive the idea of clean code differently from testers)?

This spring, Uncle Bob comes to St. Petersburg to give talks at our three conferences: they are about .NET development, testing and JavaScript. Therefore, we’ve asked speakers from each of those conferences to share their opinion on clean code so we could compare the opinions of the industry experts in 2020.

We've already published the results in Russian, and here's the English version. Since the topic is known to provoke discussions, feel free to give your own definition or argue about those already given!

UPD: When we posted this article, Uncle Bob had our conferences in his schedule. Unfortunately, the situation has changed. We updated this post on March 12, to avoid any misunderstanding.

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

Hello!

[UPD from 12.06.2021: if you're looking for a symbolic algebra library, AngouriMath is actively developed. It's on Github and has a website. Discord for questions]

Why does programming a calculator seem to be a task, which every beginner undertakes? History might have the answer — computers were created for this exact purpose. Unlike the beginners, we will develop a smart calculator, which, although won't reach the complexity of SymPy, will be able to perform such algebraic operations as differentiation, simplification, and equations solving, will have built-in latex support, and have implemented features such as compilation to speed up the computations.


Let's do it!

Hi, all of you collectors of exotic and plain bugs alike! We've got a rare specimen on our PVS-Studio test bench today – a game called «osu!», written in C#. As usual, we'll be looking for bugs, analyzing them, and playing.

Are you a business owner looking for PHP web development services or ASP.Net development services, but unable to decide the right technology for your project? Are you looking for the pros and cons of ASP.Net and PHP to take an effective decision?  I have tried to make this task easy for you by comparing ASP.Net and PHP in a very simple way.

There are a number of articles and blogs available over the Internet with a large amount of information about PHP Vs ASP.NET. Unfortunately, most of these blog posts are biased and typically based on promoting one over the other.  

In this blog post, I have done an unbiased comparison between the two most popular technologies i.e. PHP and ASP.NET in today’s world. 

On one side, we have PHP, the world’s most used and popular technology on the internet with billions of dedicated PHP developers across the world. On the other side, we have ASP.NET, a Microsoft platform. Sometimes, it becomes quite difficult to have a clear decision about which technology (Php or Asp.net) should we prefer for our application or website development project? 

Here is an elaborative comparison guide that helps you figure out the best technology for your next web app development project. I can assure you that after reading this article, you’ll have a clear idea about which technology suits you better. Moreover, you can share your thoughts and feedback in our comment box. We welcome your positive feedback for appreciating our work. Also, I will be happy to hear from you if you want us to do some improvements to my article.    

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.

This article is a review of the bugs found in the Avalonia UI project with the static analyzer PVS-Studio. Avalonia UI is an open-source cross-platform XAML-based UI framework. This is one of the most technologically significant projects in the history of .NET as it enables developers to create cross-platform interfaces based on the WPF system. We hope the project's authors will find this article helpful in fixing some of the bugs, and convincing enough to make static analysis part of their development process.

Hi to all fans of bugs! The New Year is coming soon, so it is time to take stock of the the outgoing year. By tradition, we're glad to present the top list of errors found by the PVS-Studio team in open C# projects in 2019. Ready? Then let's get going.

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.

You can see all of the release notes for the year here.

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.

We’re excited to announce the release of .NET Core 3.1. It’s really just a small set of fixes and refinements over .NET Core 3.0, which we released just over two months ago. The most important feature is that .NET Core 3.1 is an long-term supported (LTS) release and will be supported for three years. As we’ve done in the past, we wanted to take our time before releasing the next LTS release. The extra two months (after .NET Core 3.0) allowed us to select and implement the right set of improvements over what was already a very stable base. .NET Core 3.1 is now ready to be used wherever your imagination or business need takes it.

You can download .NET Core 3.1, for Windows, macOS, and Linux:

• .NET Core 3.1 SDK and Runtime
• Docker container images
• Snap installer

ASP.NET Core and EF Core are also being released today.

Visual Studio 2019 16.4 was also released today and includes .NET Core 3.1. It is a required update to use .NET Core 3.1 with Visual Studio. For Visual Studio 2019 users, we recommend simply updating Visual Studio to 16.4 and instead of separately downloading .NET Core 3.1.

Visual Studio for Mac also supports and includes .NET Core 3.1, in the Visual Studio for Mac 8.4 Preview channel. You will need to opt into the Preview channel to use .NET Core 3.1.

Release notes:

• .NET Core 3.1 release notes
• GitHub issue for .NET Core 3.1 issues
• GitHub release

We are excited to announce .NET Core support for Pulumi! This announcement means you can declare cloud infrastructure — including all of Azure, such as Kubernetes, Functions, AppService, Virtual Machines, CosmosDB, and more — using your favorite .NET language, including C#, VB.NET, and F#. This brings the entire cloud to your fingertips without ever having to leave your code editor, while using production-ready «infrastructure as code» techniques.

Though it seems we are just a few months away from reaching 2020, these months are also important in the field of software development. Here in this article, we will see how the coming year 2020 will change the lives of software developers!

Future Software Development Is Here!

Traditional software development is about developing software by writing code and following some fixed rules. But the present-day software development witnessed a paradigm shift with advances in Artificial Intelligence, Machine Learning, and Deep Learning. With the integration of these three technologies, developers will be able to build software solutions that learn the instructions and add extra features and patterns in data that are needed for the desired outcome.

Let’s Try Out With Some Code

Over time, the neural network software development systems have become more complex in terms of integrations as well as layers of functionality and interfaces. Developers can build a very simple neural network with Python 3.6. Here’s an example of a program that does binary classification with 1 or 0.

Of course, we can start by creating a neural network class:


import numpy as np

X=np.array([[0,1,1,0],[0,1,1,1],[1,0,0,1]])
y=np.array([[0],[1],[1]])

Applying the Sigmoid function:

def sigmoid ():
   return 1/(1 + np.exp(-x))
def derivatives_sigmoid ():
   return x * (1-x)

Training the Model With Initial Weights and Biases:

epoch=10000
lr=0.1
inputlayer_neurons = X.shape[1]
hiddenlayer_neurons = 3
output_neurons = 1

wh=np.random.uniform(size=(inputlayer_neurons,hiddenlayer_neurons))
bh=np.random.uniform(size=(1,hiddenlayer_neurons))
wout=np.random.uniform(size=(hiddenlayer_neurons,output_neurons))
bout=np.random.uniform(size=(1,output_neurons))

For beginners, if you need help regarding neural networks, you can get in touch with top software development company.Or, you can hire AI/ML developers to work on your project.

ML.NET is a cross-platform, machine learning framework for .NET developers, and Model Builder is the UI tooling in Visual Studio that uses Automated Machine Learning (AutoML) to easily allow you to train and consume custom ML.NET models. With ML.NET and Model Builder, you can create custom machine learning models for scenarios like sentiment analysis, price prediction, and more without any machine learning experience!

ML.NET Model Builder

This release of Model Builder comes with bug fixes and two exciting new features:

• Image classification scenario – locally train image classification models with your own images
• Try your model – make predictions on sample input data right in the UI

When you think about Jupyter Notebooks, you probably think about writing your code in Python, R, Julia, or Scala and not .NET. Today we are excited to announce you can write .NET code in Jupyter Notebooks.

Try .NET has grown to support more interactive experiences across the web with runnable code snippets, interactive documentation generator for .NET core with dotnet try global tool, and now .NET in Jupyter Notebooks.
