無法啓動升級後的應用程序Asp.net beta8

最近升級從ASP.NETβ7的到beta8以下這些優秀說明我的應用程序：http://wildermuth.com/2015/10/20/Upgrading_from_ASP_NET_5_Beta_7_to_Beta_8 無法啓動升級後的應用程序Asp.net beta8

不幸的是我仍然無法啓動我的應用程序。如果我嘗試使用Kestel（web）啓動，則在調試之前，我會收到500內部服務器錯誤，甚至會在Startup.cs中觸發我的斷點（它仍然會觸發我的斷點）。如果我嘗試在IISExpress推出我得到以下錯誤：

Could not load type 'Microsoft.Dnx.Host.Clr.EntryPoint' from assembly 'Microsoft.Dnx.Host.Clr, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. 

[TypeLoadException: Could not load type 'Microsoft.Dnx.Host.Clr.EntryPoint' from assembly 'Microsoft.Dnx.Host.Clr, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.] 
System.Web.HttpRuntime.HostingInit(HostingEnvironmentFlags hostingFlags, PolicyLevel policyLevel, Exception appDomainCreationException) +303 

[HttpException (0x80004005): Could not load type 'Microsoft.Dnx.Host.Clr.EntryPoint' from assembly 'Microsoft.Dnx.Host.Clr, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.]

System.Web.HttpRuntime.EnsureFirstRequestInit(HttpContext context) +90 
System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +261

我到處找，並與其他beta8例子無濟於事。爲什麼我無法再啓動應用程序？這裏是我的適用文件 -

運行dnvm列表時選擇了哪個運行時？我想知道它是否意外地指向beta7？您是否還安裝了最新的Web工具以及beta 8安裝？ –

像@ armen.shimoon說的，看看你的項目的屬性，看看是否設置了正確的DNX版本。此外，請確保您安裝了Visual Studio的最新版本的DNVM和WebTools。 – Epiplon

我知道我已更新dnvm以使用beta8，並指向項目屬性中的beta8。我也使用.net 4.5.1而不是核心，因爲並不是所有的庫都可以與核心（react.net，signalr）一起工作。我很確定我更新了VS web工具，但會在我能的時候檢查。 –

首先，請確保您的項目配置爲以Beta8（項目屬性）運行，並且您的dnvm list顯示您擁有beta8 inst alled。

然後，請確保您沒有AspNetLoader.dllwwwroot\bin中的任何地方。

準備好了嗎？

Microsoft.Dnx.Host.Clr.EntryPoint是ASP.NET 5和IIS之間的Helios填充（AspNetLoader.dll）的入口點。下面是你應該做的，使其工作：

確保Startup.cs:Configure方法具有以下行頭：app.UseIISPlatformHandler()
確保你沒有以下環境變量設置：WEBPROJ_ENABLEBETA7RENAMES
更新global.json爲最新的運行時版本。

這應該讓你去。告訴我你是否有不同的錯誤信息。

這是我的source。
