gacutil manages the Global Assembly Cache (GAC) for .NET assemblies. The GAC stores shared assemblies that can be used by multiple .NET applications.
On Linux, gacutil is provided by Mono. It installs, uninstalls, and lists assemblies in the GAC. Strong-named assemblies can be shared across applications through the GAC.

-i assembly

Install assembly to GAC.

Uninstall assembly from GAC.

List assemblies (optionally filtered).

Install assemblies from list file.

Uninstall assemblies from list file.

Package name for installation.

Specify GAC directory.

Root directory for operations.

Requires strong-named assemblies for GAC installation. Mono's GAC differs from Windows .NET GAC. Root privileges may be required. .NET Core doesn't use GAC; assemblies are self-contained.

The GAC was introduced with .NET Framework 1.0 by Microsoft for assembly sharing. Mono implemented compatible tools including gacutil for cross-platform .NET development. With .NET Core/.NET 5+, the GAC model was replaced by NuGet packages.
