Referencing an self-contained exe project from a framework-dependent project is currently broken.

[VictorioBerra]

Describe the bug

Referencing an self-contained exe project from a framework-dependent project is currently broken.

See: dotnet/runtime#3569 (comment)

To Reproduce

https://github.com/VictorioBerra/netcore-console-test-exe

Build the test project, try and run the exe in MyApp.Console.Tests\bin\Debug\net7.0\MyApp.Console.exe

Exceptions (if any)

A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in 'C:\Program Files\dotnet\'.
Failed to run as a self-contained app.
  - The application was run as a self-contained app because 'C:\Users\toryb\Desktop\dotnet-testing-cli-issue\MyApp.Console.Tests\bin\Debug\net7.0\MyApp.Console.runtimeconfig.json' did not specify a framework.
  - If this should be a framework-dependent app, specify the appropriate framework in 'C:\Users\toryb\Desktop\dotnet-testing-cli-issue\MyApp.Console.Tests\bin\Debug\net7.0\MyApp.Console.runtimeconfig.json'.

Further technical details

• Include the output of dotnet --info
• The IDE (VS / VS Code/ VS4Mac) you're running on, and its version
