@GooRiOn Can you review this? These changes would be handy for me. Also, why Redis persistence is not available through Nuget?

First of all, thx for the effort you put to add EF Core support. However, there are quite a few thing that needs to be changed when it comes to code styling, but also the concept overall. Maybe I miss something but to me the UoW should not be public at all. Feel free to comment on this one!

PS. I promise, next reviews won't take that much time ;)
