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

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：

  *    1.0.0-beta5-11624    clr     x86          <mypath>\.dnx\packages       default

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 .
