Emmit entities as records

[xperiandri]

Can we emmit entities as records? To change them and execute update.

@xperiandri unfortunately records are not supported by type providers (currently). You can manually do copy-and-update though, since all table entities have constructors on them. Alternatively we could look at making the table entities mutable, although I'm not so excited by the idea of doing that.

Thoughts welcome!
