@KieranJeffreySmart thanks for sharing your findings. It seems like the main issue is around versioning, and how the buildpacks can hand a version with rc in its value? But the actual buildpack functionality more or less works with the RC version?

Yes this seems to be the case. The RC version works without any obvious issues.
The versioning issue could be seen as a general buildpack feature, assuming you want to identify the behavior for any pre-release version which follows the semver standard format of major.minor.patch-prerelease (not just .net)
