ASP.NET vNext - MissingMethodException:找不到方法:Microsoft.CodeAnalysis.Diagnostic> EmitResult.get_Diagnostics()'

Dot*_*att 6 .net c# asp.net-core-mvc vs-2015-preview dnvm

我今天早上升级到VS2015 RC,我使用ASP.NET 5模板 - 网站创建了一个新项目.我有一个错误,我无法解决:

处理请求时发生未处理的异常.

MissingMethodException:找不到方法:'System .Collections.Immutable.ImmutableArray`1 Microsoft.CodeAnalysis.Emit.EmitResult.get_Diagnostics()'.

Microsoft.AspNet.Mvc.Razor.RoslynCompilationService.Compile(RelativeFileInfo fileInfo,String compilationContent)

这是完整的错误堆栈:

我也尝试使用1.0.0-beta5-11596和1.0.0-beta4 clr,但我得到了相同的结果.

任何的想法？

谢谢.

我认为大卫是对的，我也遇到了同样的问题，我能够通过以下方式解决它：

  • 打开 %USERPROFILE%\.dnx 目录
  • 删除包目录中的所有内容
  • 从运行时目录中删除 beta5 目录
  • 更改别名目录中 defaults.txt 的值以指向 beta4 运行时之一

一旦我这样做了，我就打开了项目备份，包成功恢复，并且我能够运行该应用程序。无论出于何种原因，defaults.txt 都被指向 beta5 运行时，假设这是在使用命令行工具时设置的。

希望这也适合你！
