.NET

Being able to edit your C# (or F# for that matter) code on your Linux VM from Visual Studio in Windows is pretty great. As a Windows developer, you're able to work in an environment you know and trust while still being able to experiment -- and hopefully produce production code -- in Linux, where you may not be quite up to speed. Yet. Visual Studio, that familiar, productive and helpful IDE, is at your fingertips even though your code...

In the process of writing my posts ( #1 and #2 ) on . NET Core and RHEL , it was made clear to me by several friends that I had neglected to use the de facto standard for continuous integration on Linux, Jenkins . Always happy to try out new (to me) tools, I settled in for what I was assured would be a simple configuration to test out my previous work in this bastion of automation. What is...

Running .NET on Linux, using the Red Hat Container Development Kit (CDK), means your Linux VM is running "headless" -- you don't have a desktop UI. You have a command line, and that's it. Note: If you aren't running .NET on Linux, hop over to the Red Hat Developer's web page and download the CDK to get started. Red Hat Enterprise Linux's built-in editor, VIM, which is launched by the command vi , is not a full-featured development environment. Not...

Service Bus is, according to Microsoft, “...a generic, cloud-based messaging system for connecting just about anything.” Most commonly used as an Azure service, it can be an excellent tool for managing non-critical workloads within an application and offers the benefit of being AMQP compatible when compared to Amazon’s SQS . Connecting to Service Bus (SB) on Windows is simple, but will the new .NET Core (DNX) platform be capable of the task? Library Adventures As of the writing of this...

If you are not already familiar with it, dotnetConf 2016 was an online event about .NET, and it was announced at this event that .NET Core RTM would be released at 6/27, at Red Hat Summit in San Francisco. There are several .NET meetups called dotnetConf.local , of which dotnetConf 2016 Japan is one such event. I had the pleasure of giving a session about .NET Core on Red Hat Enterprise Linux. This event was held with the cooperation of...

This post may be short, but if you're new to .NET Core, it's valuable. After installing .NET on RHEL, you want to get up and running as quickly as possible. After all, what good is a framework without anything to show for it? Well, fearless developer, wait no more; here are a few dotnet commands that will take you from a command prompt to a web site, and beyond: By now, you might know this basic command to create a...

Those looking to ascertain the ubiquitous nature of open source need look no further than the trajectory of .NET, Microsoft’s widely-adopted general development platform. In November 2014, Microsoft announced the open sourcing of .NET with .NET Core , a just-in-time (JIT) compiler and runtime for .NET. Then, in November 2015, Red Hat and Microsoft announced a landmark relationship , which established our collaboration with and promised access to .NET on the world’s leading enterprise Linux platform: Red Hat Enterprise Linux...

"There is already a command line for it, why can't my favorite editor support this language?" As a developer, you're probably familiar with this sentiment, and in reality t here has never been a better time to be a software developer. Developers have access to a growing list of languages, frameworks, libraries, and technologies that can help them solve the problems they are tasked to tackle. However, the abundance of choices often hinders the ability of Integrated Development Environments (IDEs)...

We are delighted to share that Scott Hanselman of Microsoft will join Red Hat during the DevNation 2016 opening general session. Scott is one of the world's leading technical speakers who's been deeply involved in the community and on social media, with well over 150,000 Twitter followers. Join us at DevNation to learn what news news he may share. Lots of people know Scott, but if you don't, here's his BIO: Scott is a web developer who has been blogging...

With recent changes the to the.NET ecosystem, developers of popular languages such as C# now have the ability to develop and deploy .NET applications across multiple platforms including OSX and Linux. This is made possible thanks to the .NET Core , a modular implementation of the .NET framework capable of supporting both web and console applications. Aside from opening up opportunities to a new pool of potential developers, .NET Core also enabled these applications to take advantage of certain technologies...

In my first .NET core post , I set out on a journey to conquer the new world of .NET Core (formerly DNX) on Red Hat Enterprise Linux (RHEL). In my ignorance I believed I would do a short post on firing up RHEL, installing .NET Core, and then converting an application from .NET to .NET Core before adding it as a build job to a new TeamCity instance. The best laid plans seem to be the ones that get...

Despite spending plenty of time in Red Hat Linux while I was young, I have become an unabashed Windows environment super-user/programmer. Still, it’s hard to discount the multitude of ways that the *nix community stands ahead and alone, so when Microsoft and Red Hat announced their partnership to bring .NET to Linux, I had no choice but to take notice. As an experiment, I am going to go through setting up Red Hat Enterprise Linux (RHEL) and .NET Core to...

The ASPNET Music Store application was built to demonstrate MVC and Entity Framework running on the newest .NET platform, including .NET Core. If you visit the link, you'll see that various platforms are mentioned, including Mono. However, you'll also notice that the instructions are dated: references to dnx and dnu are throughout the README file. This blog post will show how to bring MusicStore up-to-date and run it on Red Hat Enterprise Linux (RHEL). (If you don't have RHEL, you...

Red Hat is committed to making .NET a First Class citizen on Red Hat Enterprise Linux (RHEL). To that end, we're working furiously to make sure everything's perfect before we make .NET available by simply running: yum install rh-dotnetcore10 In the meantime, I can't wait. No, literally, I can't wait --- you don't need to either. You can hop over to Microsoft's .NET download site and get .NET for RHEL. (What? You didn't get your zero-dollar developer copy of RHEL...

As .NET Core matures into a production-ready software product, more and more information is becoming available regarding what to expect. While the changes haven't been too big to understand, there are breaking changes and they do require that developers get some education before forging ahead. That applies to Entity Framework Core 1.0 (EF Core) as much as any other component of what is broadly termed ".NET Core". Granted, EF Core is not a part of .NET Core -- and neither...

If you are a Windows developer and you want to start writing .NET code in Linux, and you're not sure where to start, this article should help you understand some of the choices regarding your development environment. I’ll be using the Red Hat Enterprise Linux Developer Suite (RHEL) as my Linux of choice, which is freely downloadable for development use. It's also worth mentioning that how you actually install RHEL will affect your development experience. The up-front work to get...

With the advent of .NET Core 1.0, things have changed. Dramatically. For starters, it's open source. This means anyone, including you and I, can submit bug fixes and enhancements to the .NET framework. It will now run on Mac and Linux. You can compile code natively to the platform of your choice. And beyond that, it's much more modular. There's the Common Language Runtime (CLR), the CoreFX (where the "System." libraries live), the Command Line Interface (CLI), and other modules...

I'm a .NET developer at heart, and I want to write C# code that runs natively in Linux - Red Hat Enterprise Linux (RHEL), to be specific. So, I hopped over to the Red Hat .NET Developers web site , installed the CDK and was up and running in short order. I had a no-cost developer's copy of RHEL running on my PC and was writing .NET code. Life was good. I had my instance of RHEL inside a Vagrant...

Much has changed in the IT world in the last few years, first Microsoft Loves Linux and now Red Hat Loves .NET . I suspect for many of you it is a bit bewildering, however, there are huge wins here for software developers. C# is rapidly becoming the programming language with the greatest number of target platforms, including: iOS, Android, OSX, and now through the partnership with Red Hat (home of the worlds' most popular enterprise Linux platform) C# is...

Back in November we announced that we would be partnering with Microsoft to make a supported version of .NET available for Red Hat Enterprise Linux. Since then we’ve been working together to make sure that .NET runs great on RHEL and has the capabilities that enterprise developers require. Today, at Microsoft Build, we were invited to join Scott Hanselmann on stage where we demonstrated some of that work and showed how the partnership is helping to create a more stable...

The .NET framework is a relatively young technology when compared to the rest of computer science history, but as it turns fourteen this year, we can look back and see a long-standing record of innovation, developer productivity, and more recently a refreshing open-source mentality from Microsoft that has resulted in the first ever release of (the official) .NET framework in a Linux distribution. .NET is a development platform that includes several programming languages, notably C# and Visual Basic, and the...

We are heading to Moscone in San Francisco. Yes, for DevNation in June, but we are there for Microsoft Build 2016 this week. We’ve got many exciting things planned - some below and some you will need to wait and see - but as a first time sponsor of Build we are looking forward to welcoming the .NET audience to Red Hat Developers. All the details are here but here are some of the highlights: Red Hat Developers team will...

Today is a pretty exciting day if you’re an enterprise developer. . . Red Hat and Microsoft have announced that the two companies will be working together to bring a supported version of the .NET runtime to Red Hat’s Enterprise Linux and OpenShift 3. This offers developers more freedom and choice in how they develop their applications. Having spent a big part of my career at Microsoft and working with .NET since its inception, I’ve grown to love the strengths...
