It's not the fault of the language, it's just the nature of infrastructure code that's been ported from terraform. With Pulumi C# you end up with multiple nested objects/dictionaries with a load of `new` object calls that just add noise to your codebase. There's also some pain points with some types being Input<T> which IDEs try to autocomplete when in reality you need to call `new T()`. Typescript permits structural typing that _feels_ a lot better to write and read within this context.

I use C# extensively for most other things I do, but this the one area where I prefer not to use it.
