In the past I've worked on several .NET projects that included EFCore+PostgreSQL and labelled entities, that you could filter with kubernetes-like label-selectors. I also saw Hetzner use this mechanism for their Cloud API (see https://docs.hetzner.cloud/#label-selector) and this made me think: maybe it's useful to share some functionality that I've been using for this topic in the past, packaged nicely as a small toolkit.

It supports all major EFCore providers including: PostgreSQL, Pomelo.MySql, SqlServer, Sqlite.

I hope someone out there who wants to build such mechanisms in the world of .NET may find this helpful.

Any feedback is appreciated.
