EF Core briefly had a (beta-level) MongoDB-compatible provider. It wasn't very useful in practice, but EF Core blogs every now and then talk about returning to document database support as a possibility. I don't think I would use EF Core with a document database, but I can understand the appeal in sharing models with EF Core, and maybe even utilizing a shared "Change Tracker". Unless you are doing your own things, most EF Core models should be POCOs easily enough serializable to JSON to directly use in your document DB, and EF Core contexts at this point have an easy enough Change Tracker API to query that you could possibly reuse it easily enough for a document DB (though that is probably overkill because you don't need per-property tracking at that point usually, just per-document tracking).
