C# Microsoft.VisualStudio.Services.WebApi错误

我有一个ASP.net MVC Web应用程序运行在.net Framework v4.6.1上，它指的是库项目，而库项目又指的是Nuget软件包“Microsoft.TeamFoundationServer.ExtendedClient”v14.89.0。此软件包依赖于Nuget软件包“Microsoft.VisualStudio.Services.Client”v14.89.0等

今天，我将“TeamFoundationServer.ExtendedClient”升级到了v15.112.1（最新版本），这反过来又将“VisualStudio.Services.Client”更新到了相同的版本

升级后，我在运行web应用程序时遇到以下错误：

System.TypeLoadException occurred
  HResult=0x80131522
  Message=Could not load type 'Microsoft.VisualStudio.Services.Extension.InstalledExtension' from assembly 'Microsoft.VisualStudio.Services.WebApi, Version=15.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

该错误不是在WebApiConfig.Register方法中发生的，而是在控件返回到应用程序\u Start（）方法之后发生的。在检查程序集时，我注意到更新版本中确实缺少类型“Microsoft.VisualStudio.Services.Extension.InstalledExtension”

我试图跳过将文件复制到web应用程序的bin文件夹，但这导致“Microsoft.VisualStudio.Services.WebApi.dll”出现FileNotFound异常

---

如果我需要继续使用更新的Nuget软件包，有没有关于如何解决此错误的建议？

删除bin和obj文件。然后进行全面重建，看

我已经做了，但没有帮助。虽然我无法理解这会有什么帮助，因为“Microsoft.VisualStudio.Services.Extension.InstalledExtension”类型在“Microsoft.VisualStudio.Services.WebApi.dll”中缺失。

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    GlobalConfiguration.Configure(WebApiConfig.Register);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}
