Some Useful Visual Studio Code Snippets

by

A couple of months ago, I got inspired to really learn .NET Core and Visual Studio Code (VSCode).  But I didn’t just want to learn it from Windows — the real power of .NET Core is that’s cross-platform.  So what did I do?  I bought a MacBook Pro and made that my primary work machine.  

The thing that really became clear once I started working a lot in VSCode was how much I relied on the CodeRush templates in Visual Studio 2017 — both the ones out of the box and the ones that I’d written — to get work done.  I kept doing all the CodeRush keyboard shortcuts in VSCode that I had ‘muscle memory’ for and (of course) they did nothing.  (Grrr.)

Well, because I had a huge looming deadline for my next Pluralsight course, the only reasonable thing to do was to spend a day learning how to write VSCode Snippets and to write snippets for all the things that I missed from full Visual Studio 2017.  

Here’s my pile of C# snippets.  Download and enjoy.  

To install these, open up Visual Studio Code, bring up the list of commands (CTRL-Shift-P / Command-Shift-P), and search for Configure User Snippets.  This will bring up your snippets info.  Choose ‘csharp’ and then copy the my snippets into your csharp.json snippets file.  You could also just replace your csharp.json snippets file with my file if you don’t already have any snippets that you’ve written.  

Once you’ve gotten those installed, to use them, type the keyboard shortcut value in VSCode and press Tab to expand the snippet.  Some of the snippets take multiple values.  Press Tab to move between the snippet values.

I hope you get some use out of these.

  1. Neat stuff. Too bad you moved away from full VS and CodeRush just in time for them to introduce the ability to inline images in code comments (http://devexpress.com/holygrail). That stuff is pretty cool and I can see some serious gains in understanding what code is doing since pictures can convey so much more than mere words at times.

    That said, the moment people start introducing animated images (I’m looking at you Azure Devops Pull Requests…) things could go completely off the rails. Time will tell though.
