I deleted a reference to `EntityFramework` and I don't know where I can find it on my computer.

`EntityFramework` is installed by NuGet and it's still on the project. But without the reference, it can't find `DbContext`.

The first solution is to uninstall and install after, but others reference need to have `EntityFramework`, so I don't want to uninstall it.

I need to find a way to add the reference.

Thanks
