In my experience, most C# Pulumi implementations were complex enough to crash VSCode's C# extension language engine a fair amount of the time, and cause it to heavily lag if not crash. If you're able, I recommend trying out Visual Studio, especially if you're able to use the Community license
No matter how you like to participate in developer communities, Pulumi wants to meet you there. If you want to meet other Pulumi users to share use-cases and best practices, contribute code or documentation, see us at an event, or just tell a story about something cool you did with Pulumi, you are part of our community.
