Visual Studio Code Plugins (Format / Spell Check)

It's been a few months since the question was asked (and answered), but thankfully, things have changed!

VSCode now support extensions!

Here's a relevant excerpt from the above blog post:

Extension Marketplace/Gallery

To complement the extensibility mechanism, we have also launched an in product gallery and web based extension marketplace. These allow you to discover and install extensions. To open this up in VSCode, simply hit F1 and select Extensions: Install Extensions.

Alternatively, you can browse the Extension Marketplace at https://marketplace.visualstudio.com/#VSCode.

I gave the marketplace a quick search and easily found multiple extensions for spelling and source formatting, but I'll forego making any specific recommendations since everyone's requirements are different.

For anyone looking to write their own extensions for VSCode, take a look at the documentation for extending VSCode, as it has a lot of the information you'd need to start writing your own extensions.

Lastly, thanks to Daniel for his comment. It helped me find the information I needed, but to save future visitors some time, I thought it was worth sharing my findings.

Plugin support is not currently enabled in the VSCode editor. The development team were not happy with the plugin API, so they have disabled them until further work can be made on this.
