6 years ago Hi Gavin,
I apologize for not updating the repo on a while. The first part of the year has been very busy and stressful for me!
The dependencies have changed, and I need to update them. I'll try to get around to it this weekend. Once the latest version of EFCore is stable, I should be able to cut the first official release and things like this shouldn't happen again.

6 years ago Please see also the discussion around classes and methods internal to EF Core for another EF Core DB provider: https://github.com/PomeloFoundation/Pomelo.EntityFrameworkCore.MySql/issues/497
It might be a good idea to get rid of any dependencies on those references.

6 years ago Yeah, I've been through this refactoring hurdle several times already...
However, I have to use a not insignificant amount of their "internal" classes in order to work around some of the assumptions the EF Core team makes in their API. They assume things like a relational database, or that data comes back as an indexed array of values. Since I'm wrapping the MongoDB C# driver, and letting it handle the Linq query translation, I have to work around a lot of assumptions about the shape of the returned data: namely that it's already a document/object instances. Because of the limited surface of the "external" API, I HAVE to use the "internal" code in order to work around their assumptions.

6 years ago I suggest that you raise this with the EF Core team

6 years ago @ErikEJ Someone from their team is supposedly working on some other Document DB provider, and wrapping an existing Linq provider for it. So I've been waiting on them to figure out their own problems and get them fixed. But you're probably right, it's probably time for me to pester them some more. Maybe some prodding will help them get out a Document DB layer that will clean up some of this mess, or at least a layer that more readily allows for wrapping an existing Linq provider. Either one would be huge for my provider.

This has been fixed. You should be able to pull the latest version from MyGet.
