Question

使用Visual Studio Performance Explorer和Cassini，我正在尝试在我的（Orchard CMS 1.4.0）ASP.NET MVC3应用程序上启动性能分析，但是我收到此错误：

无法正确配置网站;获取ASP.NET进程信息失败。请求http://localhost:30320/OrchardLocal/VSEnterpriseHelper.axd返回错误：远程服务器返回错误：（404）Not Found。

所以我搜索了一个解决方案，发现this article不适用，因为我使用的是Visual Studio的开发服务器（Cassini）而不是IIS - 不过IIS 6.然后我读了this article和this article;在所有这些建议中，唯一有所作为的是将location部分添加到我的web.config中，以授予对VSEnterpriseHelper.axd的访问权限。但正如其中一篇文章预测的那样，我的404错误只是变成了500：

无法正确配置网站;获取ASP.NET进程信息失败。请求http://localhost:30320/OrchardLocal/VSEnterpriseHelper.axd返回错误：远程服务器返回错误：（500）内部服务器错误。

这些不同文章中的尾随评论对我不起作用。有什么建议？我想我会在这里发布我的（Orchard 1.4.0）web.config，以防有人发现罪魁祸首：

Answer 1

就我而言，我有

    <validation validateIntegratedModeConfiguration="true" />

在我的web.config中设置。当我把它改成

    <validation validateIntegratedModeConfiguration="false" />

事情神奇地开始起作用了。三个小时下来......

Answer 2

我遇到了类似的问题，我找到了一个解决方案。我发现我得到了404错误，因为VSEnterpriseHelper.axd通过MVC路由，并且它发生在我Web.config中设置的任何内容中。所以我发现我应该正确地路由它。所以我添加了路由来处理这个文件，我写了处理程序：

<强>处理程序：

public class DefaultRouteHandler : IRouteHandler
{
    public IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        return new DefaultHttpHandler();
    }
}

internal class DefaultHttpHandler : IHttpHandler, IRequiresSessionState
{
    public void ProcessRequest(HttpContext context)
    {
        string contentPath = context.Request.PhysicalPath;

#if DEBUG
        if (contentPath == context.Server.MapPath("VSEnterpriseHelper.axd"))
        {
            var assembly = AppDomain.CurrentDomain.GetAssemblies().SingleOrDefault(a => a.GetName().Name == "Microsoft.VisualStudio.Enterprise.AspNetHelper");
            if (assembly == null)
            {
                if (File.Exists(@"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Enterprise.AspNetHelper.dll"))
                {
                    assembly = Assembly.LoadFrom(@"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Enterprise.AspNetHelper.dll");
                }
                if (File.Exists(@"C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Enterprise.AspNetHelper.dll"))
                {
                    assembly = Assembly.LoadFrom(@"C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Enterprise.AspNetHelper.dll");
                }
            }
            var type = assembly.GetType("Microsoft.VisualStudio.Enterprise.Common.AspNetHelperHandler");
            var handler = (IHttpHandler)Activator.CreateInstance(type);

            handler.ProcessRequest(context);
            return;
        }
#endif
        [...]
    }   
}

路线定义：

DefaultRouteHandler defaultHandler = new DefaultRouteHandler();
routes.Add(new Route("{*resource}", new RouteValueDictionary(), new RouteValueDictionary(), defaultHandler));

Answer 3

我修正了相同的500错误，这是您需要做的事情（部分借用here借用我自己的评论）：

确保您对web.config文件具有写入权限
如果您的网站已锁定根文件夹的安全性（使用其中任何一个）表单或Windows身份验证等），请确保添加[location]标记以允许完全访问vsenterprisehelper.axd文件，如下所示：
```
<location path="VSEnterpriseHelper.axd">
    <system.web>
        <authorization>
            <allow users="?" />
        </authorization>
    </system.web>
</location> 
```
确保在IIS中为您的站点配置了AXD扩展
如果您的AppSettings存储在单独的配置文件中，并且您的web.config使用configSource属性引用它们，则会出现问题

Answer 4

我终于（4小时后）通过将我的默认.axd route handler从RouteConfig.cs移到主Global.asax.cs来解决此问题：

AreaRegistration.RegisterAllAreas();
// Register .axd route ahead of WebApiConfig
RouteTable.Routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);

因为我使用的是WebAPI，所以WebApiConfig路由正在接收对AXD的调用，因为它们在RouteConfig.RegisterRoutes之前注册，默认情况下.axd exception。
