dotnet restore using RID causes "empty" project.assets.json file (netcoreapp3.0) #10312
Description
First a little bit of background.
I am one of the collaborators over at the dotnet-script repo.
We use dotnet restore as a way of getting a list of dependencies we need to execute a script.
So we basically generate a csproj file behind the scenes that looks like this.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp2.1</TargetFramework>
</PropertyGroup>
</Project>
Then we do a runtime specific restore
dotnet restore -r osx-x64
This generates the project.assets.json file we need to read out the dependencies.
Compilation deps are listed in the file as
"ref/netcoreapp2.1/Microsoft.CSharp.dll": {},
"ref/netcoreapp2.1/Microsoft.VisualBasic.dll": {},
"ref/netcoreapp2.1/Microsoft.Win32.Primitives.dll": {},
"ref/netcoreapp2.1/System.AppContext.dll": {},
and so on
Same for runtime deps
"runtimes/osx-x64/lib/netcoreapp2.1/Microsoft.CSharp.dll": {},
"runtimes/osx-x64/lib/netcoreapp2.1/Microsoft.VisualBasic.dll": {},
"runtimes/osx-x64/lib/netcoreapp2.1/Microsoft.Win32.Primitives.dll": {},
"runtimes/osx-x64/lib/netcoreapp2.1/Microsoft.Win32.Registry.dll": {},
Basically all the deps coming from Microsoft.NetCore.App
Note: We use the
LockFileclass fromNuGet.ProjectModelto read the file.
Okay so here is the problem we are facing.
if we change the target framework to netcoreapp3.0, the project.assets.json file no longer gets populated with these dependencies.
So given the following project file
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp3.0</TargetFramework>
</PropertyGroup>
</Project>
and then dotnet restore -r osx-x64
What we see here is that all the compile deps and runtime deps are "missing" from the project.assets.json file.

With target framework set to netcoreapp2.1 the project.assets.jsonfile gets populated with all the resolved deps as "expected".
Is there any way to achieve the same behaviour with target framework set to netcoreapp3.0?
We have discovered though, that if we explicitly add a package reference to Microsoft.NetCore.App [3.0.0-preview5-27626-15], things are back to "normal".
We would very much like to avoid to adding this reference explicitly as we then need to know the .Net Core runtime version.
Any input/workaround on this would be greatly appreciated.
Steps to reproduce
Create a new console app (netcoreapp3.0)
dotnet new console
dotnet restore -r osx-x64
Expected behavior
project.assets.json file to be populated with resolved runtime and compilation deps
Actual behavior
project.assets.json files contains no runtime and compilation deps.
