Libraries can be shared with other .NET platforms, such as .NET Framework (Windows) and Xamarin (mobile applications). With...

.Use .NET APIs to portably locate special folders (app and user data/confgiuration) in your cross-platform applications. The Linux behaviour of these APIs are demonstrated.

This post describes how to secure ASP.NET Core applications on OpenShift using HTTPS for two use-cases: terminating SSL in OpenShift for public routes and terminating SSL in ASP.NET Core directly using OpenShift-generated service certificates.

Microsoft's decision to make .NET Core open source and cross-platform means it's

This article shows how set up Microsoft SQL Server on Red Hat OpenShift and then use SQL Server to store data for a simple ASP.NET Core application running in a container deployed on OpenShift that manages a list of contacts. It also shows how to manage SQL Server within OpenShift using SQL Operation Studio.

Kestrel, the web server in the .NET Core, supports replacing the network layer. This article benchmarks Kestrel’s networking layer with a Linux-specific implementation to achieve measurable performance gains compared to the out-the-box implementation.

In this article, I show how you can call the Red Hat OpenShift REST API from your C# code, which is useful for automating tasks. Visual Studio is used to take the REST API definition and create a library you can use in your code. Also shown is how to handle the conversion needed for the JSONpath components.

Containers are the new way of deploying applications. They are an efficient way to portably deploy applications across clouds and different OSes.This article looks at what OpenShift brings for .NET Core specifically and how OpenShift provides a DevOps platform on top of Kubernetes for building and deploying apps.

We are very pleased to announ ce the general availability of .NET Core 2.1 for Red Hat Enterprise Linux and OpenShift platforms! .NET Core is the open-source, cross-platform .NET platform for building microservices. .NET Core is designed to provide the best performance at scale for applications that use microservices and containers. Libraries can be shared with other .NET platforms, such as .NET Framework (Windows) and Xamarin (mobile applications). With .NET Core you have the flexibility of building and deploying applications...

Learn how to remotely debug an ASP.NET Core container pod on Red Hat OpenShift using Visual Studio from a Windows computer.

For added security, .NET Core applications that require access to external libraries can be run in a disconnected environment (one without internet access). Here's how.

At Red Hat Summit 2018, Red Hat’s John Osborne and Microsoft’s Harold Wong gave a talk: Developing .NET Core Applications on Red Hat OpenShift. .NET Core 1.0 availability for Linux was announced two years ago, but many developers still have a number of questions about the differences between .NET Framework and .NET Core.

Today we're going to create a .NET Core 2.0 Web Application using the JBoss Developer Studio and the aCute plugin (C# application development). We'll deploy our application onto an OpenShift instance and continue to modify it while viewing the changes almost instantly. Although the initial setup will be quite involved, it will only need to be done once. You might imagine that the normal workflow for this would be: Make local changes. Commit + push them to version control. Either...

I've started an interesting exploration on the integration of Microsoft Windows Containers and Linux Containers in an OCP Environment. This allows a true bi-modal IT technical implementation by combining the strength of both platforms into one cluster. So, I start this off, with the deployment of an OpenShift Cluster on Azure, using the 3.6 reference architecture. After this is run, I used the Azure Portal to add a Windows Server 2016 Node to the cluster. So if you look closely...

Visual Studio provides a graphical remote debugging ASP.NET Core app with Docker Tools for Windows. Since Visual Studio supports SSH protocol, you can remote debug ASP.NET Core process running on the Linux host. It used to be if you install and setup SSH server on docker container, you can remote debug with Visual Studio. However, it's strongly not recommended due to security reasons. Now I'll explain to you how to remote debug your ASP.NET Core on OpenShift with Visual Studio...

Most books teaching C# start with a 'Hello World' application. This simple program is used to explain concepts like namespaces, classes, Main and Console.WriteLine. When every line of the code has been dissected, it's clear how it works. It's less obvious for an ASP.NET Core application. We are no longer invoking our code; instead, the ASP.NET Core framework is doing that for us. In this blog post, we'll look at a simple ASP.NET Core application and explain how ASP.NET Core...

When you build your .NET Core project, NuGet packages are retrieved from nuget.org by default. Sometimes, however, you might want to use a local NuGet repository. For example, you may want to: use private NuGet packages, but you don't want anyone except your associates to see them. cache a NuGet repository at a server near your build servers leave your build server disconnected from the Internet. I'll explain how to set up a private NuGet server on OpenShift and how...

D-Bus is a Linux message bus system. Many system daemons (like systemd, PulseAudio, bluez) and desktop services can be controlled via D-Bus. Some applications can be reached via the global system bus and others are on a per-user-login-session bus. Higher-level bindings are available for various popular frameworks and languages. Tmds.DBus is a .NET implementation. The library is based on dbus-sharp/ndesk-dbus, which target Mono/.NET 2.0. Tmds.DBus leverages async/await (Task-based asynchronous pattern) introduced in .NET 4.5/C# 5.0. The library targets netstandard1.5 which...

This release improves the experience of...

Introduction to NuGet with .NET Core NuGet is an open source package manager for the .NET Core ecosystem. For those familiar with Red Hat Enterprise Linux (RHEL), you can think of it as the “yum” for pulling libraries into your .NET Core project. Working with NuGet packages in .NET Core applications is accomplished primarily through your project’s .csproj file and the dotnet command-line interface. Repositories Just like RHEL, NuGet has its own repositories to get packages. By default, when the...
