At work, we are planning to migrate our WPF application from .NET Framework 4.7 to .NET Core 3.0. The main reason for doing so is that it was always a big pain to organize the updates of the .NET Framework on our customer machines. So being able to bundle .NET Core with our application is a big plus for us. Then, for sure, we are looking for the performance improvements brought by .NET Core and finally the new capabilities brought by the fast pace of innovation of .NET Core.

Rust – the Ultimate Programming Language?
What makes a good programming language? Syntax? Compiler? Tools and ecosystem? It is tempting to say “all of that” but in that case, why there are so many different programming languages? All these components are very important but they alone can’t make the language “good”. One of essential things is the purpose — like languages for rapid development, or development of distributed algorithms, or general purpose for high-level and low-level applications, or easy to learn, or safe to use and so on.
Rider 2022.1 includes full Unreal Engine support, which converts Rider into a full-fledged IDE for game development, no matter what game engine you use.
In v2022.1, Rider also supports a Beta version of the long-awaited remote development workflow. It allows you to connect to a remote machine running Rider’s backend from anywhere in the world.
In addition to these new features, this release also brings Docker Fast mode, updates to the main toolbar, and full-text search throughout the solution right from the Search Everywhere pop-up.

orchard core دیگر یک وب سایت مدیریت محتوا نیست !
در نسخه Core این پروژه ( که به صورت کامل باز طراحی و بازنویسی شده ) تبدیل به یک سایت ساز شده است .
It is a completely new thing written in ASP.NET Core. The Orchard CMS was designed as a CMS, but Orchard Core was designed to be an<< application framework >> that can be used to build a CMS, a blog or whatever you want to build

} Have you ever wanted to build something but you had no idea what to do? Just as authors sometimes have "writers block" it's also true for developers. This list is intended to solve this issue once and for all! 👍
Go, also referred to as Golang is a program created by Google. It was designed by Ken Thompson, Rob Pike, and Robert Griesmer. Golang is one of the most rapidly growing languages in terms of popularity. Ken Thompson, Rob Pike, and Robert Griesmer created Go Language to be a language that has numerous cores, implements concurrency easily, works smoothly in a distributed environment and allows the programmer to write programs without too much hustle. Go language also has a lean and user-friendly syntax.
