There’s some nice plugins too, some are finance related:

The one thing I really want is for someone to make it so I can use it in F#. Presumably it's possible given how the python bit is implemented under the hood?
It uses pyo3 to generate the bindings, so you would have to find a similar crate for F#/.NET and port the polars Python FFI to it. If such a crate does not exist, it will be even more work.
