问题
I recently upgraded from ASP.NET Core 2.2. to 3.0. With the changes regarding their meta packages, I'm now in a state where everything works, but some pretty important packages are not explicitly referenced. Everything works because, they're implicitly referenced. For example:
You can see that I'm explicitly referencing Microsoft.EntityFrameworkCore.SqlServer, however I am NOT referencing Microsoft.EntityFrameworkCore explicitly. It's still pulled in because it's an indirect reference it seems.
My question is: is this a reasonable project configuration? Is there any advantage to pulling in Microsoft.EntityFrameworkCore explicitly? I imagine there may be implications in terms of version upgrades.
Thanks...

Yes. Transitive dependencies are absolutely a thing in SDK-style projects, and in my experience they make life much simpler.
I would only add a redundant NuGet reference in order to specifically upgrade that package - and I'd be careful only do to that for minor releases. For example, if I use package A v1.0 that depends on package B v1.1, I might add a dependency on package B to upgrade to v1.2, but not to v2.0.
