Source of the ZGacInst - my little utility that will add assemblies to and remove them from GAC. Replaces GacUtil, which MS for some reason keeps weirdly licensed.

ZGacInst.cs

// GacUtil my own way.
// Since GacUtil is not distributed with .NET framework (after 1.1.), should yo uwant to install your assemblies to GAC,
// you are likely to need this code.


using System;

// Add reference: System.EnterpriseServices

namespace ZGacInst
{
    class Program
    {
        static void Main(string[] args)
        {
            if (args.Length != 2 || (args[0].ToLower() != "-i" && args[0].ToLower() != "-u"))
            {
                Console.WriteLine("Error. Usage: \"ZGacInst -i <path>\" or \"ZGacInst -u <path>\".");
            }

            if (args[0].ToLower() == "-i")
            {
                new System.EnterpriseServices.Internal.Publish().GacInstall(args[1]);
            }
            else if (args[0].ToLower() == "-u")
            {
                new System.EnterpriseServices.Internal.Publish().GacRemove(args[1]);
            }
            else
            {
                Console.WriteLine("Error. Usage: \"ZGacInst -i <path>\" or \"ZGacInst -u <path>\".");
            }
