swupd-client VS NetSparkle

I have tried a simple recreate making a tar with a few hard linked files and not hit the problem. The closest equivalent I could find was this but they were writing their own extract code and messing with paths during the extract. That shouldn't happen with the tar command.

Along with some of the other comments, there is NetSparkle for C#-based apps: https://github.com/NetSparkleUpdater/NetSparkle (disclaimer: I am the primary maintainer of this repository).

We eventually settled on a combination of InnoSetup with InnoSetuo Dependency Installer and NetSparkle which offered a much cleaner experience and use of AzureAD Authentication for Azure Storage Blobs (for updates) as well as InTune Deployments with proper version detection.

Before we stopped developing Desktop Applications, NetSparkle was our preferred choice but you have to provide your own installer (we used InnoSetup.

She also had a rather sour attitude we didn't care much for (example). We finally settled on NetSparkle as it allowed us to have complete control over the frontend implementation. The added pluses were not being forced to adopt SemVer behavior, improved digital signature signing and the ability to both sign the update and the manifest.

Are there any good update libraries that implement digital signatures like ed25519? Like self_update but with digital signatures, or something like NetSparkle for rust. Assume I don't want to update from a github or anything.
