c# - 无法加载文件或程序集 'Microsoft.Framework.Logging.ILoggerFactory' 或其依赖项之一

Question

在我新的 asp.net 5 应用程序中，我有这个错误:

Could not load file or assembly 'Microsoft.Framework.Logging.ILoggerFactory' or one of its dependencies. The system cannot find the file specified

System.IO.FileNotFoundException Could not load file or assembly 'Microsoft.Framework.Logging.ILoggerFactory, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

但是我已经在 project.json 中添加了引用

我错过了什么？

奇怪的是它会构建!

您应该更新到最新版本(撰写本文时为 Beta 7，尽管 Beta 8 将于下周发布)。 Beta 4 现在有几个版本已经过时并且非常不稳定。

正如@Geerten 所建议的，您还需要添加 Microsoft.Framework.Logging。您可以从官方 announcement 了解有关升级到 Beta 7 的更多信息.请注意，Beta 7 也有新版本的工具，因此您需要安装它。
