You'all spoke and we've listened. I've dusted off my old very barebones prototype, pushed it to a branch at https://github.com/pulumi/pulumi/tree/ellismg/add-dotnet, and will be hacking on this over the course of the next week. Collaborators are welcome (please do join the #contribute channel in our slack at https://slack.pulumi.io). And watch the branch, I expect we'll have something usable in a few days and it might help folks who are interested in supporting other languages with Pulumi.

In the meantime, as someone who had to learn TypeScript to start using Pulumi when I started here, I do encourage you to look at some of the examples we have and play around with them. It's actually a pretty nice language and with VSCode it's pretty easy to get started.

(Disclosure: I still work at Pulumi)
