Red Hat Enterprise Linux is the world’s leading enterprise Linux platform, now optimized for development.
Develop applications on the most popular Linux for the enterprise—all while using the latest technologies.
Linux® is an open source operating system (OS) and IT infrastructure platform created as a hobby by Linus Torvalds in 1991. In the world of operating systems, Linux has the largest user base, is the most-used OS on publicly available internet servers, and the only OS used on the top 500 fastest supercomputers. Because the source code for Linux is freely available, there are several different distributions, including Red Hat Enterprise Linux (Red Hat's flagship product) and Fedora Linux, a community project founded by Red Hat to develop a desktop version of Linux.
Software developers create apps and services inside Linux containers that let them code once, then run their code virtually anywhere. All containerized apps contain some part of a Linux distribution. You want to make sure that all of the pieces in your container, including the Linux base, are identical between environments so you don’t have to spend your time patching and backporting.

Linux containers are what enables microservices to be built for cloud-ready applications. Learn how.
Learn about developing microservices the open source way: deployed as containers for your open hybrid cloud.
Part of the beauty of Linux containers is that they are hybrid by design. That means you can code locally, test in the cloud, and deploy anywhere that Linux containers will run. Most Red Hat developer components are available with dockerfiles, or distributed as Linux container images on Red Hat Enterprise Linux (for local dev) and Red Hat OpenShift Container Platform (local, on-line, or public cloud dev). This means that wherever you develop, test, and deploy, you’re using the same development stacks, on-premise to virtual to cloud. To help you get where you’re going faster, the Red Hat container catalog gives you access to certified, trusted and secure application containers.

We’re excited to announce the general availability of .NET 5.0 on Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, and Red Hat OpenShift Container Platform. What’s new .NET 5.0 is the successor of .NET Core 3.1, and supersedes .NET Framework as the preferred target platform for building Windows Forms and WPF applications. .NET […]
In this article, you’ll learn how to deploy Microsoft SQL Server 2019 on Red Hat OpenShift. We’ll then use SQL Server from an ASP.NET Core application that is also deployed on OpenShift. Next, I’ll show you how to connect to SQL Server while working on the application from your local development machine. And finally, we’ll […]
Have you ever wanted to set up continuous integration (CI) for .NET Core in a cloud-native way, but you didn’t know where to start? This article provides an overview, examples, and suggestions for developers who want to get started setting up a functioning cloud-native CI system for .NET Core. We will use the new Red […]
In previous articles, we covered C# 8 asynchronous streams, C# 8 pattern matching, C# 8 default interface methods, and C# 8 nullable reference types. In this final article, we’ll look at static local functions, indices and ranges, and using declarations. static local functions C# 7 introduced local functions, which are defined and used inside the […]
In the previous article, we discussed C# 8 default interface methods. In this article, we’ll look at C# 8 nullable reference types. Reference types refer to an object that is on the heap. When there is no object to refer to, the value is null. Sometimes null is an acceptable value, but often it is […]
