Manual repro steps

1. Create a .csproj resembling this:

<Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>netcoreapp2.1</TargetFramework> <RuntimeIdentifiers>win-x64;osx-x64</RuntimeIdentifiers> </PropertyGroup> </Project>

2. dotnet restore --use-lock-file
   • This will succeed and write a lock file
3. dotnet restore --use-lock-file --locked-mode
   • This will fail with error NU1004: The packages lock file is inconsistent with the project dependencies despite the fact that the file was just generated and nothing has changed.

Tagging @nkolev92 and @rrelyea as FYI.
