无法加载文件或程序集“Microsoft.VisualStudio.Diagnostics.PerformanceProvider，版本=14.0.0.0

Question

发布到生产时出现错误程序集

到目前为止，我已经尝试过：

1. 清洁bin和obj
2. 重建解决方案
3. 手动添加Microsoft.VisualStudio.Diagnostics.PerformanceProvider库
4. 设置应用程序池以启用 32 位应用程序
5. 在生产服务器上安装 Visual Studio

Answer 1

解决方案1：

卸载并重新安装 Visual Studio

解决方案2：

只需从框架目录中的 web.config 文件中删除对此程序集的引用。

解决方案3：

使用管理员权限打开 Visual Studio

Answer 2

我遇到了同样的问题。 我认为它与动态程序集加载或 DI（例如 AutoMapper）有关。 在我的情况下，我们最终拥有一台构建机器（没有安装 VS）来执行构建输出并且工作正常。

Answer 3

以下应该解锁...

        AppDomain.CurrentDomain.AssemblyResolve -= AssemblyResolveEventHandler;
        AppDomain.CurrentDomain.AssemblyResolve += AssemblyResolveEventHandler;


        private static readonly ResolveEventHandler AssemblyResolveEventHandler = (sender, resolveEventArgs) =>
        {
            var assemblyName = GetAssemblyName(resolveEventArgs.Name);
            var assemblyDllPath3 = Path.Combine(@"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\PrivateAssemblies", $"{assemblyName}.dll");
            var assembly = (File.Exists(assemblyDllPath3) ? Assembly.LoadFrom(assemblyDllPath3) : null);
            return assembly;
        };

        internal static string GetAssemblyName(string fullAssemblyName)
        {
            const string AssemblyNamePattern = "^([^,]+)([,].+)*$";
            return Regex.Match(fullAssemblyName, AssemblyNamePattern).Groups[1].Value;
        }

Answer 4

在将我的项目从 VS-2013 迁移到 VS-2019 时，我在服务器中遇到了同样的问题。 我通过将程序集复制到GAC_MSIL(C:\\Windows\\Microsoft.NET\\assembly\\GAC_MSIL)文件夹来纠正它。
