Are you going to add C# support?
We are actively working on https://github.com/pulumi/pulumi/issues/2430, which will make it easier for our small team to manage multiple languages. Once that lands, I would expect this to be high priority.
Some of our amazing community members have been prototyping this, and it's looking pretty promising: https://twitter.com/MikhailShilkov/status/109278757393889689....

Powershell would be great, it has nice support for building DSLs.
