我有自己的 Visual Studio 2008 SP1 自定义工具。它由 5 个程序集组成：3 个程序集的代码在我的其他项目中大量使用，1 个 VS2008 SDK 之上的程序集包装器和一个带有该工具的程序集。
如果我要从 Visual Studio 调试我的工具，请使用带有命令行“C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe”和参数“/ranu/”的“运行外部程序”选项rootsuffix Exp" 一切正常。
之后，我尝试将其部署到我的工作 VS 副本，而不是实验性配置单元，为我所有的程序集做：gacutil /i Asm1.dll为我的所有程序集做，RegAsm Asm1.dll只为使用自定义工具的程序集做。utils 都没有打印任何错误，所有工作都按计划进行，甚至出现注册表项。但即使在 PC 重新启动后，我的工具也无法工作（发生错误“在此系统上找不到自定义工具 'TransportGeneratorTool'”）。我做错什么了？
包装器看起来像这样：
[ComVisible(true)]
public abstract class CustomToolBase : IVsSingleFileGenerator, IObjectWithSite
{
#region IVsSingleFileGenerator Members
int IVsSingleFileGenerator.DefaultExtension(out string pbstrDefaultExtension)
{
pbstrDefaultExtension = ".cs";
return 0;
}
int IVsSingleFileGenerator.Generate(string wszInputFilePath, string bstrInputFileContents, string wszDefaultNamespace, IntPtr[] rgbOutputFileContents, out uint pcbOutput, IVsGeneratorProgress pGenerateProgress)
{
GenerationEventArgs gea = new GenerationEventArgs(
bstrInputFileContents,
wszInputFilePath,
wszDefaultNamespace,
new ServiceProvider(Site as Microsoft.VisualStudio.OLE.Interop.IServiceProvider)
.GetService(typeof(ProjectItem)) as ProjectItem,
new GenerationProgressFacade(pGenerateProgress)
);
if (OnGenerateCode != null)
{
OnGenerateCode(this, gea);
}
byte[] bytes = gea.GetOutputCodeBytes();
int outputLength = bytes.Length;
rgbOutputFileContents[0] = Marshal.AllocCoTaskMem(outputLength);
Marshal.Copy(bytes, 0, rgbOutputFileContents[0], outputLength);
pcbOutput = (uint)outputLength;
return VSConstants.S_OK;
}

生成的注册表项：
