Question

这个问题是关于过时的测试版，可能会被删除

在安装DNX beta7和用于Beta 7的ASP.NET Visual Studio工具后，在Visual Studio 2015中打开时，基于“ASP.NET 5预览模板”（现在称为ASP.NET Core）的小应用程序提供了以下内容错误：

---------------------------
Microsoft Visual Studio
---------------------------
Cannot find DNX SDK version 'dnx-clr-win-x86.1.0.0-beta6-12256' required by 
your solution. Do you want to install it now? If you select No, 
‘dnx-clr-win-x86.1.0.0-beta7’ will be used as the solution DNX SDK version
for this session.
---------------------------
Yes   No   
---------------------------

选择Yes会在DNVM输出窗格中导致以下消息框和以下错误输出：

---------------------------
Microsoft Visual Studio
---------------------------
DNX SDK version 'dnx-clr-win-x86.1.0.0-beta6-12256' failed to install. 
The solution will use DNX SDK version ‘dnx-clr-win-x86.1.0.0-beta7’ for 
this session.
---------------------------
OK   
---------------------------

DNVM输出面板：

有趣的是，当我运行dnvm命令列出DNX运行时，从我的PowerShell中，它列出了1.0.0-beta5，beta6，beta7已安装并出现在我的c:\Users\USERNAME\.dnx\runtimes文件夹中。

发生了什么以及如何解决这个问题？

解决此问题（使用RC测试）：

dnvm update-self
dnvm upgrade

将早期beta版ASP.NET核心项目升级到另一个早期测试版时，在Visual Studio 2015中打开时会出错
