Files not merging - "Package reference missing 'compile' part in IncludeAssets"

[64ZooLane]

Files not merging when building.

• Output Window Messages
  MSBUILD : warning FodyPackageReference: Fody: The package reference for Costura.Fody is missing the 'compile' part in the IncludeAssets setting; it's recommended to completely remove IncludeAssets
• Your Code (small reproducible sample)
  I haven't added anything to the code
• If there is an exception/crash - provide the full stack trace
  Doesn't crash.

Steps to reproduce

1. Build

Platform: Windows 10
.NET version: 3.1

Expected behaviour

Tell us what should happen:
Build with all files combined into 1

Actual behaviour

Tell us what happens instead:
Shows that message in the build output and all the files are still scattered.

I think it should work with this:

<PackageReference Include="Costura.Fody" Version="5.7.0" PrivateAssets="all" />
