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 becoming a first class citizen on Linux:
Installing .NET is as simple as issuing the following commands in your RHEL terminal (You will need to grab the .NET RPM installation files we used for the April 12 Sneak Peek from github):
yum install -y rh-dotnet-core10 scl enable rh-dotnet-core10 bash
Note: The yum install and scl enable commands (above) are as of April 12, where we used a nightly build. You will want to double-check the release notes when .NET on Red Hat Enterprise Linux (RHEL) reaches an official Beta/Technology Preview status, and is released through official channels.
Now let's get a simple "hello world" app running. The following commands will create a new project, build, and run it. It's hard to get much easier than this when bootstrapping a new project:
mkdir hello cd hello dotnet new dotnet restore dotnet run
If you're reading this and thinking, "but I don't have RHEL 7.2 so I can't try this out," you can actually download our Hyper-V and VirtualBox images in which we've pre-installed .NET, Docker and Visual Studio Code on RHEL 7.2.
Note: The pre-installed Visual Studio Code did not yet have the C# extensions installed, so just click when prompted for the installation:
Prompt to install C# extensions

If you're new to Linux entirely, we also have a cheetsheat for the Linux command line to help you navigate and learn your way.
To stay current on future .NET on developments on RHEL, keep an eye out for Twitter traffic for #dotNETonLinux and periodically revisit redhatloves.net.
The recording for our April 12 Sneak Peak is available online. If you have an hour, please give it a watch and give us your feedback. Lastly, f you want to deliver your own .NET on Linux presentation, our slides are available via Google Docs, feel free to download and fork them for your own needs. All of the example .NET code is available at https://github.com/DonSchenck/DotNetOnLinux.
