Mixed Project References

Hey Folks, I often run into the case where I have one project that needs the output from another. For example i have ProjectA which is net8.0 and it needs the binaries from ProjectB which is compiled using net48. I can't add a project reference because they are different runtimes. I have tried to do 
<ItemGroup>
  <ProjectReference Include="ProjectB">
    <ReferenceOutputAssembly>false</ReferenceOutputAssembly>
  </ProjectReference>
</ItemGroup>
<ItemGroup>
  <ProjectReference Include="ProjectB">
    <ReferenceOutputAssembly>false</ReferenceOutputAssembly>
  </ProjectReference>
</ItemGroup>
However you get the error This project may not be fully compatible with your project. which is weird because it's not a reference. So I add 
<ItemGroup>
  <ProjectReference Include="ProjectB">
    <ReferenceOutputAssembly>false</ReferenceOutputAssembly>
    <SkipGetTargetFrameworkProperties>true</SkipGetTargetFrameworkProperties> <!--- Add this -->
  </ProjectReference>
</ItemGroup>
<ItemGroup>
  <ProjectReference Include="ProjectB">
    <ReferenceOutputAssembly>false</ReferenceOutputAssembly>
    <SkipGetTargetFrameworkProperties>true</SkipGetTargetFrameworkProperties> <!--- Add this -->
  </ProjectReference>
</ItemGroup>
However the explodes with doesn't have a target for 'net8.0' which is true because it's a net48 project. Is there a clean way to set this up without having to do a bunch of MSBuild targets?

the cleanest way is to have the projects talk over some framework-agnostic interface, i.e. a HTTP call or whatever
This project may not be fully compatible with your project
isn't this a warning by default, though? .net core has a 'compatability shim' by default where it will try its best to work with .net framework assemblies (it just doesn't promise it won't explode if the framework assembly does something unsupported) i know this because my work solution used to be in this situation
