Specifying framework version of dependency manually in SDK style project

I am updating an old project to the SDK style and I have a reference that looked like

    <Reference Include="Package, Version=1.2.3.4, Culture=neutral>
      <HintPath>$(EnlistmentRoot)\packages\Package\lib\net45\Package.dll</HintPath>
    </Reference>

    <Reference Include="Package, Version=1.2.3.4, Culture=neutral>
      <HintPath>$(EnlistmentRoot)\packages\Package\lib\net45\Package.dll</HintPath>
    </Reference>

After moving to SDK style I had

    <PackageReference Include="Package" Version="1.2.3.4" />

    <PackageReference Include="Package" Version="1.2.3.4" />

Which caused the build system to select the net46 version of the package not the net45 which turns out to be important. How can I override that behavior? Going back to the <Reference seems to work but it'd be nice to use PackageReference if possible.

You'll need a combo of PackageRef with ExcludeAssets="all" and GeneratePathProperty="true", then a Reference element pointing at <package path>\lib\net45\package.dll

Which, IMO, is better than just a raw Reference

Okay so what that gets me is that the version isn't hardcoded in my reference anymore correct? So it can be found by dotnet build and such. Easily restored globally etc.

Correct The SDK generates where the package path is, so you no longer need to care if it's at EnlistmentRoot, ~/.nuget, or wherever else You only need to care about the path within the package

Okay that sounds like a reasonable compromise to me, thanks! Right now we've got a single packages.config and 100% hardcoded <References so it'll be nice to let that go
