Asp.net mvc 4 移动到Web API RC，获取：未找到方法：'；System.Web.Http.Services.DependencyResolver System.Web.Http.HttpConfiguration.get#u servicesolver（）'；

我将一个站点从WebAPI Beta移动到WebAPI RC，现在加载该站点时出现错误：

未找到方法：“System.Web.Http.Services.DependencyResolver System.Web.Http.HttpConfiguration.get_servicesolver（）。

第一次尝试注册我的

AutoFacWebApiDependencyResolver

（按照说明）时发生错误：

stacktrace显示以下内容：

[MissingMethodException: Method not found: 'System.Web.Http.Services.DependencyResolver System.Web.Http.HttpConfiguration.get_ServiceResolver()'.]

基于此，该错误似乎发生在静态GlobalConfiguration类的初始化过程中。当我深入到该类的源代码时，我看到以下内容：

[MissingMethodException: Method not found: 'System.Web.Http.Services.DependencyResolver System.Web.Http.HttpConfiguration.get_ServiceResolver()'.]

  return local_0;

private static Lazy<HttpControllerDispatcher> _dispatcher = new Lazy<HttpControllerDispatcher>((Func<HttpControllerDispatcher>) (() => new HttpControllerDispatcher(GlobalConfiguration._configuration.Value)));

public static HttpConfiguration Configuration
{

    return GlobalConfiguration._configuration.Value;
  }
}

private static Lazy\u配置=new Lazy（（Func）（（）=>

私有静态惰性_dispatcher=new Lazy（（Func）（（）=>newhttpcontrollerdispatcher（GlobalConfiguration._configuration.Value））；
公共静态HttpConfiguration

这里的第四行似乎是问题所在-它试图调用一个get_servicesolver（）方法，该方法在

HttpConfiguration

类中不再存在（应该是

DependncyResolver

）

这只是RC for WebAPI的一个bug吗？有什么办法可以让我绕过这件事吗？或者我被困在某个DLL/Nuget地狱中（如果是这样，我如何才能脱身）？

依赖解析已完全用RC重新编写。最好是卸载测试版DLL，然后您的问题很可能会消失

只需卸载windows“卸载程序”中标记为“（bundle）”的程序即可。

确保包含正确的nuget软件包（RC！），并在生成软件包的计算机上安装新的mvc4rc。

卸载屏幕中没有任何内容包含“（bundle）”唯一的mvc4条目是我今天安装的RC。从计算机上卸载了所有nuget软件包和mvc4，并重新安装了它们，然后它工作了。一定是剩下什么东西了。
