Lots of people are using open source .NET Core and the "dotnet" command line, but few know that the .NET CLI supports command "tab" completion!

You can ensure you have it on .NET Core 2.0 with this test: 

dotnet complete "dotnet add pac"

The main change in this release is a security fix, and it’s possible you will need to change your own code to adapt. Here’s why: jQuery used a regex in its jQuery.htmlPrefilter method to ensure that all closing tags were XHTML-compliant when passed to methods. For example, this prefilter ensured that a call like jQuery("<div class='hot' />") is actually converted to jQuery("<div class='hot'></div>"). Recently, an issue was reported that demonstrated the regex could introduce a cross-site scripting (XSS) vulnerability.

I was pleasantly surprised by how easy it was to setup and install ASP.NET Core 2.1 on Linux. I did it for the first time in 15 minutes with no previous experience with .NET Core on Linux. I did it the second time, in production, in 5 minutes by following these instructions.

In this article, I show you how to install the .NET Core runtime on CentOS, how to get a sample ASP.NET Core project running on Kestrel as a service for reliability, and how to configure both the code and the firewall to enable remote access. Finally, I discuss what I would do differently for actual production usage.
