What Developers Need to Know About Progressive Web Apps 

What are digital signatures and what do they tell us, what information do they hold? All this and more are explained in this article. 

Account

A bank account allows us to send and receive money and has its unique number. Anytime we tell about an account in a bank, an account is always a bank account. In the other hand, an account in an information system is used to authorize a user. We have the term "account" meaning something absolutely different in two different domains. Domain has an impact on what we imagine when someone says a concrete term. So we have to learn and specify domain terms first.

Price

Let's speak about e-shop domain. What is a price? For us, as customers, it is how much we pay. A manager can think about price as an amount that his company pays to the supplier. For an accountant, a price is just a number. And e-shop programmer is now confused.

Language is crucial because customers and experts are telling their stories in their language. But it is also natural language, inaccurate, ambiguous, context-aware. And as we can see, language can be tricky even within one domain. 

Here are the features that we have in the latest alpha build of React 18

Visual Studio Code doesn't support solution files, whereas Visual Studio does. In Visual Studio we use solution files to link multiple projects together, and at first I thought that this was going to be a deal breaker for Visual Studio Code - but it's not at all. Many people aren't aware that Visual Studio Code, although lightweight, is a powerful editor that can do most of the things you need. 

Irrespective of what technologies your remote team uses, there are numerous VS Code plugins you will find useful, but this article will only cover those I have used extensively. 

We are going to talk about:

What you get out of the box with ASP.NET Core 2.0
How to use Postman to test your API
Changing the default configuration of our project
Testing the content negotiation
Restricting media types
More about formatters
Implementing a custom formatter
Consuming API programmatically 

C# Language Features by Versions
This page contains all the features introduced to C# with a link to all the proposals and documentation.
This is a great way to find out if you are missing out on new features that can make your developer life easier. 

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 come alive with the previews of Visual Studio 2019 that we are working on.
