Hello!
I was trying to create a CRUD-operations system inside my Unity project, but I could not find out how to import external packages to my Unity project as Microsoft.Data.Sqlite or Microsoft.EntityFrameworkCore, 'cause when I try to open NuGet Package Manager, VS tells me there is no project that supports NuGet on my Unity project:
Can someone tell me if it is possible, and how I could do that?
Last I was aware Unity didn’t support NuGet. I think you can add support for it through the following open source asset but I’ve never tried it.
I didn’t want to install unofficial tools, I also want to learn how could I do that.
But thanks for the suggestion.
Up to you. Just be prepared to spend a ton of time getting nothing done while you sort through it all. 
It’s only for learning purposes. I’ll probably use web requests for communicating with an API that integrates the database.
There is a Nuget-for-Unity (or similar name) up on Github. You have to use that one.
I uninstalled it right away because it clutters the Assets tree with some DLLs just to more easily download a package.
It was not necessary to use that one.
Simply adding the required classlib from sqlite and referencing it on my assembly it worked.
Forgot to update here last year.
