Upgrading V9 to V10 causes dependency missing errors

It would appear this is related to changes in the paket.targets.

The error we get on build is that there are missing dependencies.

These are framework projects targetting 4.7.1.

A big difference i can see in the generated "obj" files is that in project.assets.json all dependencies are now missing.
The same is trie in the csproj.nuget.dgspec.json under the "net471" framework.

I think it's this change https://github.com/fsprojects/Paket/pull/4247

The dependencies file we have:

source https://[REDACTED]
source https://[REDACTED]
source https://[REDACTED]
strategy: min
redirects: on

nuget package1
nuget package2 ~> 1.0.0

the lock file adds restriction: >= net471 to all top level dependency lines.

the reference file has all the dependencies we reference, 99.9% of which will be 2nd level dependencies (so in the lock, but not in the dependencies file)

we use "package2" to set a standardised version of all external dependencies across multiple repository

Start by comparing paket.targets and the generated project.assets.json and csproj.nuget.dgspec.json files for the net471 framework before and after the V9-to-V10 upgrade. Review the referenced Paket change and inspect how the dependencies, lock, and reference files are interpreted. Done means framework projects restore all expected direct and transitive dependencies and build successfully.
