将 dll 注册到 GAC - 但随后它不会显示在程序集窗口中

我有这段代码将 dll 注册到我的 gac 中

 Assembly asm = Assembly.LoadFrom(argument);
    RegistrationServices regAsm = new RegistrationServices();
    bool bResult = regAsm.RegisterAssembly(asm, AssemblyRegistrationFlags.SetCodeBase);

这工作得很好，我对 bResult 很忠诚，但是当我打开 GAC 窗口时，我希望在那里看到 dll，但事实并非如此。谁能解释一下为什么？

当我将 dll 放入 GAC 窗口时，我在那里看到它。

相当奇怪的是，它没有被 .NET 框架封装。必要的融合声明很容易获得。这段代码运行良好：

using System;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.ComTypes;

static class GacUtil {

    public static void InstallAssembly(string path, bool forceRefresh) {
        IAssemblyCache iac = null;
        CreateAssemblyCache(out iac, 0);
        try {
            uint flags = forceRefresh ? 2u : 1u;
            int hr = iac.InstallAssembly(flags, path, IntPtr.Zero);
            if (hr < 0) Marshal.ThrowExceptionForHR(hr);
        }
        finally {
            Marshal.FinalReleaseComObject(iac);
        }
    }

    public static void UninstallAssembly(string displayName) {
        IAssemblyCache iac = null;
        CreateAssemblyCache(out iac, 0);
        try {
            uint whatHappened;
            int hr = iac.UninstallAssembly(0, displayName, IntPtr.Zero, out whatHappened);
            if (hr < 0) Marshal.ThrowExceptionForHR(hr);
            switch (whatHappened) {
                case 2: throw new InvalidOperationException("Assembly still in use");
                case 5: throw new InvalidOperationException("Assembly still has install references");
                case 6: throw new System.IO.FileNotFoundException();    // Not actually raised
            }
        }
        finally {
            Marshal.FinalReleaseComObject(iac);
        }
    }


    [ComImport, InterfaceType(ComInterfaceType.InterfaceIsIUnknown), Guid("e707dcde-d1cd-11d2-bab9-00c04f8eceae")]
    internal interface IAssemblyCache {
        [PreserveSig]
        int UninstallAssembly(uint flags, [MarshalAs(UnmanagedType.LPWStr)] string assemblyName, IntPtr pvReserved, out uint pulDisposition);
        [PreserveSig]
        int QueryAssemblyInfo(uint dwFlags, [MarshalAs(UnmanagedType.LPWStr)] string pszAssemblyName, IntPtr pAsmInfo);
        [PreserveSig]
        int CreateAssemblyCacheItem(/* arguments omitted */);
        [PreserveSig]
        int CreateAssemblyScavenger(out object ppAsmScavenger);
        [PreserveSig]
        int InstallAssembly(uint dwFlags, [MarshalAs(UnmanagedType.LPWStr)] string pszManifestFilePath, IntPtr pvReserved);
    }

    [DllImport("mscorwks.dll", PreserveSig = false)]  // NOTE: use "clr.dll" in .NET 4+
    internal static extern void CreateAssemblyCache(out IAssemblyCache ppAsmCache, int reserved);
}
