Implicit restore doesn't restore enough

[0x53A]

EDIT: running dotnet restore on the console fixed it.

The following behavior is on my work pc with VS2017.7.3.
I can't try it on my home pc with VS 2018.8pre because I currently don't have internet there. 😱

Would appreciate guidance on whether this is a known fixed bug (can't currently test on 15.7.4 or 15.8.x), whether you can reproduce it, and if there are any workarounds.

1. Clone https://github.com/haf/expecto, checkout master.

Notice that nuget shows warnings

and almost nothing works.

Colorization is just the basic one, no class-coloring (I guess DateTime should be blue), no tooltips, no intellisense:

2. I added explicit references to System.ValueTuple (https://github.com/0x53A/expecto/tree/valuetuple), which removed the NuGet warnings, but didn't bring the tooling back to life.

3. New Project -> F# -> Class Library (.NET Standard)

Everything works

grr, running dotnet restore on the console fixed it.

I'll still leave it open, as the implicit restore should work.

Closing this as external, since this isn't a F# tooling issue. I'd suggest opening this on dotnet/project-system, which is where implicit restore at design time is handled.

Expecto uses paket, so it seems like I've hit the scenario you described here: fsprojects/Paket#3270 (comment)

I don't have a repro, which is why I haven't opened another issue, but I've hit a similar issue again. Vanilla nuget, no paket.

Open project, I get basic features, but no extended features.
Restart VS, everything works.
