Frequently asked questions
LibWatch and .NET
Do I need to install anything in the project?
No. LibWatch reads dependency files through the GitHub or GitLab API, without adding anything to your pipeline.
Are private registries supported?
Yes. A package from a private registry is identified as such: its name is never sent to a third-party service, and it stays in the project's inventory.
Does LibWatch detect the version installed on the server?
No. LibWatch reads the version declared in the repository (version file, lockfile or manifest). It has no access to your servers.
